Q: What types of mounting screws are used on ICC faceplates?

A: Majority of ICC faceplates (IC630, IC107F, IC107LF, IC107D, IC107S, IC106, and ICRDSV) come with Slotted Screws.  Only ICC stainless steel faceplates (IC107SF) come with Phillips Screws.

The deep slot on the Slotted Screwprevents the screwdriver from slipping and scraping the paint off during torque.   Slotted screwsare more expensive to manufacture due to extra milling step required to deepen the slot and are commonly used on electrical faceplates.   Phillips Screwsare designed for ease of use but tend to slip out easily damaging the head and paint.  Therefore, ICC only use it on stainless steel faceplate where there is no over paint on screws.


Q: Which of the two following terms support speed and which is correctly used for bandwidth; MHz and Mbps?

A: Mbps (mega bits per second) refers to the speed of data, whereas MHz (mega hertz) relates to the bandwidth.

Q: Should cable slack be included in installations?

Q: What are the key electrical parameters of the 10GBASE-T standard?

A: The IEEE has determined that Alien Crosstalk is the main electrical parameter limiting the performance of the structured cabling system when applied to 10transmission lines. Alien Crosstalk is a coupled signal in a disturbed pair arising from a signal in a neighboring cable. Additionally, IEEE has determined that all of the specified Category 6 electrical parameters are to be extended out to 500 MHz with Insertion Loss meeting Class F requirements.

Q: If you have a 50 µm fiber backbone, can you use 62.5 µm fiber jumpers on each end? Or vise versa?

A: From 50 µm fiber backbone to 62.5 µm fiber jumpers, it’s OK on the receiver end, but on the transmitter end, the larger core of 62.5 µm into smaller 50 µm fiber will have losses of 2~4 dB. From 62.5 fiber backbone to 50 µm fiber jumpers, the excess loss is at the receiver end, not at the transmitter end.

Q: What are the six banned substances?

A The six banned substances are Lead (Pb) Cadmium (Cd) Mercury (Hg) Hexavalent Chromium (Cr6+) Polybrominated Biphenyls (PBB) and Polybrominated Diphenyl Ethers (PBDE).

Q: Why and when to consider using Fiber?

A :If you have a run longer than 295 ft. (from 62.5 to Single Mode, Fiber allows transmissions from thousands of meters to several kilometers) (EMI) Electron Magnetic Interference is an issue. (Since Fiber uses light signal it is not susceptible to electrical signal interference) Security is a major concern. (Since Fiber uses a light signal it is impossible to tap into the signal unlike copper lines) Other things to consider: Cost – Tools, Connectors, Training, Testers, and material. Difficulty – May require special training and practice to learn termination. ICC offers pre-terminated fiber solutions for installers from dual fiber jumpers

Q: How do you classify fiber optic cable?

Q: What do PC and APC mean, with reference to Fiber Optic Connectors?

A: PC stands for Polished Connector. The end of the fiber is polished with a special polishing film to a crystal-clear finish. APC stands for Angles Polished Connector. The end of the fiber is polished with a special polishing film at an angle of approximately 8° for a superior quality finish. With this type of finish, reflected light will be absorbed in the cladding, reducing the back reflections.

Q: What is a hybrid cable?

A: A hybrid cable contains more than one fiber type in the same cable. For example, a private network application might call for both singlemode and multimode fibers. Placing both fiber types in the same cable would result in installation savings since there would be no need to install two separate cables. They can also include copper cables for Telco and /or data.

Q: Will a singlemode connector work on multimode cable?

A: Singlemode connector can be used on multimode cable but not the reverse. Singlemode connectors are made to tighter tolerance as is singlemode fiber. Multimode connectors have bigger holes for the fiber and will have high loss (>1dB) with singlemode. Also, multimode connectors may not be PC (physical contact) polish, which is terrible for return loss.

Q: Can I splice 62.5/125 µm fiber to 50/125 µm fiber? If so, what type of nominal loss would I be looking at?

A: If you splice it, you’ll get directional losses. Transmitting from 50 µm to 62.5 µm fiber, you’ll get virtually no losses but from 62.5 µm to 50 µm, you’ll get a minimum of 1.6~1.9 dB loss due to the size and NA (numerical aperture) mismatch.

Q: What are some of the uses of fiber optic cabling in the business world?

A: The biggest use is telephony, followed by CATV, then LAN backbones, connecting hubs. Next is connecting remote video cameras for security systems. The building management and security systems are switching to fiber in many buildings due to distance and EMI requirements. Fiber is not often used to the desk because it is perceived to be too expensive, but it allows a system without wiring closets, making the cost less in most instances.

Q: What applications will require 10 Gbps data rates?

A: The primary applications using 10 Gbps data rates are data centers, high-end workstations, and web-enabling applications.

Q: Is there a standard jacket color for fiber optic cables?

A: For premise cables, the jacket color is dependent upon the fiber type in the cable. For cables containing singlemode fibers, the jacket color is yellow. For cables containing multimode fibers, the jacket color is orange. For outside plant cables, the standard color is black; however, other customer preference can be accommodated as well.

Q: What is the difference between the ceramic and metal sleeve fiber adapters?

A: The metal sleeve works for multimode only where as the ceramic adapter works for single and multimode has better alignment performance.

Q: How does an optical fiber transmit light?

A: The light in fiber optic cable travels through the core (hallway) by constantly bouncing from the cladding (mirror-lined walls), a principle called total internal reflection. Because the cladding does not absorb any light from the core, the light wave can travel great distances. However, some off the light signal degrades within the fiber, mostly due to impurities in the glass. The extent that the signal degrades depends on the purity of the glass and the wavelength of the transmitted light.

Q: Should cable slack be included in installations?

A :Yes. Slack may be necessary to accommodate future cabling system changes. The recommended amount of slack is 10 feet, regardless of media, for the telecommunications closet. At the outlet, the recommended optical fiber slack is 3 feet, while one foot is recommended for twisted-pair cables.

Q: What is the difference between Singlemode and Multimode fiber optic cable?

A: Singlemode: Core size is 8.3 µm, for 1550 nm – 1300 nm wavelength range, for long distance transmission, and allows only one pathway (mode) of light. Multimode: Common core sizes are 50 µm and 62.5 µm, for 1300 nm – 850 nm wavelength range, for short distance transmission, and allow more than one pathway (mode) of light. Please Note: Although the core sizes are different, it is impossible to distinguish between the two with the naked eye.

Q: How far can I connect by using multimode or singlemode fiber optic cable?

A: Multimode fiber optic cable connects up to 2,000 meters when the network is operated in full duplex mode. It can connect up to only 200 meters in half duplex mode. Singlemode fiber optic cable can transmit from 15,000 to 60,000 meters, depending on hardware and configuration.

Q: What is insertion loss?

A: More commonly referred to as attenuation, insertion loss is the loss of signal power between two points. Items that lead to signal loss are excessive cable length, temperature, humidity, and excess return loss.

Q: What is return loss?

A: Return loss is the ratio of signal power transmitted into a system to the power reflected. An echo best describe return loss. Changes in or mismatched impedance causes signal reflection.

Q: What is the difference between Horizontal and Backbone Cabling?

A: Horizontal cabling extends directly from the horizontal cross connect in the telecommunications room to the workstations, with no splices, bridges, taps, or other connections. Backbone cabling connects the telecommunications room with outside services, or connects telecommunications rooms together within, or between buildings.

Q: What is the definition of fiber optics and what are its advantages over copper wire?

A: Fiber optics refers to the concept of transmitting information, in the form of light, through cable fibers composed of highly purified glass or plastic, clad in a reflective coating. This allows the light beam to travel the length of the cable by bouncing off the reflective sides of the fiber. The advantages of a fiber optic system are: Information carrying capacity is greatly increased, while overall size and weight of the cable is greatly reduced. Information can be transmitted at a much higher speed over long distances. Security is increased because information is transmitted in the form of light through a non-conductive media (glass), whereas, electricity traveling through wires can be tapped by an outside agent, or accidentally pick up transmissions from other sources of electro-magnetic radiation.

Q: How do I install the Fiber Optic Splice Trays?

A: Installation of the Fiber Optic Splice Trays (ICFOSTFM12 & ICFOSTFM24) is simple: Splice trays can accommodate 12 and 24 splices respectively. Select left or right angle splice holder as applicable. There are holders to accommodate Bare Fusion, Fusion with Sleeves, and Ribbon Fusion. Attach the holder to the base of the tray; ensure that access and minimum bend requirements are not compromised. Trim and clean fiber cable as mandated by policy. Secure buffer tubes using snaps or tie down wraps. It is common practice for the buffer tube stop within ¼” of attachment point. Make and secure splices to holders, ensure that fibers are not being crimped or pinched and that cover will not pinch fibers. Snap cover back onto base. Utilize Velcro® cable ties to secure tray onto mounting surface on fiber tray, if applicable.

Q: What is the purpose of the rip cord?

A The rip cord is a feature that is available for those stripping the jacket from the cable without tools. ICC recommends using either of the items: ICACSTSUCD, ICACSTSUS1, or ICACSCTRS instead to remove the jacket. Using these tools will reduce the amount of cable wasted when stripping the jacket. The rip cord feature is conveniently available with our CAT 5e UTP cable.

Q: What is the difference between CM , CMR , and CMP ratings on the UTP cable?

A These are different fire ratings that may be required by local authorities in different areas. In most cases CM is general purpose (typically used on same level cable installs), CMR (typically required for cable runs between floor levels though increasing required for use on floor level runs i.e between workstations), and CMP (typically required for cabling runs above ceilings and below floors) areas shared by air ducts. Each fire rating indicates the level of toxic fumes emiited when that cable is burned and self extinguishing features.

Q: I am having difficulty with cable snagging/kinking when pulling?

A :ICC premise cable are manufactured with patented REELEX® winding machine. The REELEX® winding method strives for wire dispersion from the pull box without twists, tangles, snags or overruns. While this is an effective method for facilitating cable pulls, its performance is susceptible to installation handling. To reduce the likelihood of pulling difficulties - Avoid shipping single cartons by courier services where the cartons may be carelessly tossed about, shifting the organized coiling within the box. Also, be careful when transporting the cartons to minimize turbulent movement impact on the inside coils. Once the box is over half-empty, the integrity of the coil is compromised and it is more prone to possible tangles when transported or moved. Avoid re-feeding wires back into the pull box which can disturb the inner coiling. Avoid stacking or pulling from the dispensing box with the dispensing opening face upward.

Q: What is the difference between CAT 6A UTP and FTP?

A :The type of twisted-pair cabling chosen makes a difference in how well a network functions. Electromagnetic and radio waves emitted by electronics or heavy machinery can affect the performance of signals traveling through network. • As a general rule, use FTP cabling in environments with high electromagnetic interference (EMI) or radio frequency interference (RFI) • In electrically quiet environments, opt for UTP cable • UTP cable offers cost savings over FTP cable due to the extra manufacturing process that is required for interference protection in a FTP cable

Q: What is the difference between stranded and solid cable?

A: Stranded cable has several small gauge wires in each separate insulation sleeve. Solid has one large gauge wire in each sleeve. Stranded cable is more flexible, making it more suitable for shorter distances and tight bends such as patch cords. Solid cable has better electrical performance.

Raceway (back to top)

Q: Does ICC manufacture clips or some other method of mounting raceways, without using sticky tape?

A: Raceways can be installed with screws on drywall or wood by drilling directly through the raceway without the need for pre-drilling.

Q: How many Category 5 cables can fit into a 0.75 inch raceway, a 1.25 inch raceway, and a 1.75 inch raceway?

Q: What's the difference between a Splitter and a Diplexer?

A: The main difference between a splitter and a diplexer is the frequencies that they handle. A splitter handles one frequency range between the two ports. Where as a diplexer has a separate frequency range on each port. Splitters main purpose is split the signal that is being fed into it. Splitters can be used as combiners, as long as the frequency stays within the spec of the splitter and will not conflict with the frequency being fed by the other port.

Q: What is the difference between a ICC splitter and other brands?

A Unlike the majority of inexpensive splitters commonly found at various electronics retailers ICC splitters are PCB based. That is, there is a sophisticated printed circuit board in every splitter to provide a very high level of isolation between signals. Better isolation means less chance for interference and distortion such as which is often caused by substandard splitters.

Q: What are the six banned substances?

A: The six banned substances are Lead (Pb) Cadmium (Cd) Mercury (Hg) Hexavalent Chromium (Cr6+) Polybrominated Biphenyls (PBB) and Polybrominated Diphenyl Ethers (PBDE).

Q: What does a splitter do?

A Splitter takes one RF or television signal and multiplies it to your desired number. ICC makes the highest quality RF splitters available. Please note: each time a coax cable is split the signal strength decreases. Additionally, the larger the splitter the more signal loss you will experience. Signal loss must be accounted for when designing an RF system.

Q :Insertion loss / dB loss when using the splitters

A: The insertion loss is measured in dB. The lower the number, the better are equally balanced and the outputs all have the same insertion loss. This is true of most splitters with two, four, or eight outputs. The average loss is 4.5 dB per split. (A two way splitter has one split, a four-way has 2, an eight way has 3.) Thus an average eight-way splitter should have about 12 to 13.5 dB insertion loss.

Q: What applications do ICC’s Category 5e products support?

A: ICC’s Category 5e products support any application that requires Category 5e, 5, 4, or 3 cabling. This includes, but is not limited to: 10Base-T 100Base-TX 100Base-T4 Token Ring 100VGanyLAN TP-PMD ATM-UTP

Q: Will ICC’s Category 5e system run 155 Mbps ATM?

Q: What is the difference between RG-59 and RG-6 cables, and can they be used on the F-Type Feedthrough Modular Connectors, IC107B5Fxx and IC107B5Gxx?

A: The difference has to do with the center pins, outer diameters, and RF loss. Both utilize 75 Ohm cable found in video applications like cable television. The center conductors are of different gauges; the RG-59 center conductor is 20-22 AWG, and RG-6 is 18 AWG. For RF loss, RG-6 performs better. The outer diameter of RG-6 is larger than RG-59, so a different size F-Type connector is needed on the individual cable ends.

Q: What are the uses for RG-6 and RG-59 cables?

A: RG-6 and RG-59 are two types of coaxial cables, and can be used with F-Type connectors for the distribution of RF signals for cable TV (CATV) and satellite (broadband), or BNC connectors for closed-circuit environments and data transmission (baseband).

Q: What does Network Topology mean?

A: 10BASE-T is the IEEE standard that defines the requirement for sending information at 10 Mbps on unshielded twisted-pair cabling, and defines various aspects of running Ethernet on this cabling. 100BASE-T is the IEEE standard that defines the requirement for sending information at 100 Mbps on unshielded twisted-pair cabling, and defines various aspects of running baseband Ethernet on this cabling. 1000BASE-T is the IEEE standard that defines the requirement for sending information at 1000 Mbps on unshielded twisted-pair cabling, and defines various aspects of running baseband Ethernet on this cabling.

Q: What is the wiring configuration for 10BASE-T?

A: Pair 1 = Pin 1(TD+), Pin 2(TD-) Pair 2 = Pin 3(RD+), Pin 6(RD-)

Q: When a second hub was installed in my network, the network no longer functioned. If the second hub is removed, the network functions properly. What are your recommendations for solving the problem?

A: The solution would be to provide a crossover cable between the two hubs. This cable should be configured so that on end is wired to T-568-A and the other end is wired to T-568-B. This configuration will cross receive-to-transmit lines and vise versa, allowing the hubs to talk to each other.

Q: What is network wiring?

A: Network wiring is any transmission path used for information rather than power. Information – in electronic form – can be voice, video, audio, or any form of computer data.

Q: What is the fire-rating or burn test rating for ICC residential enclosures?

A: The UL listing on our enclosures is based on the materials used for its construction. There are other fire ratings for enclosures such as the UL 72 which is for enclosures that store documents and so forth. Our enclosures are not designed for the storage of records our enclosures have not been tested to the UL 72 testing standards for insulated records protection equipment. Under that test the enclosures are assigned a time rating such as “One-Hour Rated Products - 1700°F”. This is mainly for products such as file cabinets, safes and so forth that is intended to help protect items such as paper records, microfilm, computer media, etc. Each has a different degree of tolerance to temperature, humidity and length of time such as during a fire. Our enclosures are designed to hold circuit boards and other connectivity products that do not require that type of protection. All of our enclosures and products within are UL listed meaning they are constructed with UL approved materials and independently tested for basic safety and flammability compliance.

Q: Can I use a coaxial splitter to distribute a satellite signal to two or more receivers?

A: No. A coaxial splitter is for CATV/CCTV use only. A device called a multi-switch is required for distribution of the satellite signal to multiple receivers. The multi-switch contains electronic circuitry that selectively routes the satellite signal from the LNB’s to each receiver. The signal routing is determined by a control voltage (and sometimes a combination of both voltage and tone frequency) that comes from the receiver, based upon channel selection. The multi-switch allows each receiver to view any channel independent of any other receiver. Coaxial splitters are passive devices, and cannot perform this type of selective signal routing.

Q: Why do LAN cables work at 10 Mbps, but not at 100 Mbps?

A: The most common problem is that Category 3 wiring may be somewhere in the system. All horizontal cabling, jack, patch cords, and equipment room cords need to be Category 5e to function properly at the higher transmission rate.

Q: What is Ethernet?

A: Ethernet is the most commonly used network protocol – a network language. With appropriate network software, any computer can understand and use it. This common protocol and its software enable computers and peripherals to communicate with each other, even if they are using different operating systems.

Q: What is the difference between a hub and a switch?

A: A hub is a device where bandwidth is shared among all devices connected to it. A switch; however, is a device where each port has it’s own dedicated bandwidth. Also, the linking maximum for a hub is two units while a switch can accommodate virtually an unlimited number of uplinked units.

Q: What is the benefit of a switch?

A: Since a hub shares all it’s bandwidth among its ports, it is generally slower and more susceptible to collisions and errors. A switch; however, with its own dedicated bandwidth, creates a separate collision domain by dedicating a full 100 Mbps line segment through each port. As well as making a switch faster and more stable, this feature provides virtually unlimited expansion, overcoming the hub uplink limitations in 10Base-T and 100Base-TX networks.

Q: How do you mount ICC’s Net Media Center enclosures (14”, 21” and 28” ) hinged doors?

A: Partially install two(2) hinged door mounting screws in either the two left or right holes on the side of the enclosure. Hang the hinged door on the two partially installed screws using the keyhole openings on the hinge. The door should fit up against the enclosure. Tighten the screws, The hinged door should overlaps ¾” over the installed enclosure to conceal any uneven drywall cuts or openings.

NOTE: Due to the hinged flange attached to either the two left or right holes on the side of the enclosure, the hinged door will surface approximately 0.15” from the drywall.

Warranty (back to top)

Q: What happens to lifetime warranty if Certified Elite Installer (CEI) is no longer in business?

A: ICC Lifetime Warranty (LW) is a joint warranty between ICC and CEI offered to the End User (EU). It is not a sole warranty from ICC to EU. ICC only provides hardware and does not sell the installation to EU, it is CEI who installs and sells the installation with labor. The lifetime warranty will become invalid when CEI is no longer doing business, However, ICC will go above and beyond to help the end user: EU can find another CEI to recertify the site and transfer the joint warranty to the new CEI. If there is an issue requiring repair, ICC will find a CEI to fix it and end user pay only a small labor cost.
