What is the capacity (number of fibers) of Ausvigor’s Fiber Optic Enclosures?
A: The capacity of Ausvigor’s Fiber Optic Enclosures is governed by two factors. It depends on the type adapter panel used in the enclosure and the maximum number of connectors for SC or ST. The are a number of different adapter panel options for each enclosure.

What type of cable is used in the horizontal cabling system?
A: Three types of cables are recommended for use in the horizontal cabling system:

Four-pair 100 Ohm unshielded twisted-pair (UTP) or screened twisted pair (ScTP) cables.Two or more optical fiber multimode cable, either 62.5/125 μm or 50/125 μm. One single mode cable.

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.

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.

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).

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.

Ausvigor offers pre-terminated fiber solutions for installers from dual fiber jumpers.

How do you classify fiber optic cable?
A: By NEC & UL – flame retardancy

By cable types (tight buffer/distribution/breakout/loose tube)
By fiber types (multimode/singlemode/hybrid)
Whether it has fiber and wire (composite cable)

What is an MT?
A: MT stands for mechanical transfer. It is a multi-fiber ferrule in which fiber alignment is critical for high performance. The key elements for fiber alignment are: 1) high precision molding. 2) high precision guide pins.

What is an MPO?
A: MPO stands for Multi-fiber Push On connector designed by NTT for the MT ferrule. The MPO connector family is defined by two different documents (or standards). Internationally, the MPO is defined by IEC-61754-7 and in the USA by TIA-604-5 (also called FOCIS 5).

What is an MTP?
A: The MTP is an improved MPO connector design trademarked by US Conec Ltd. The MTP is fully compliant with all MPO standards (FOCIS 5 and IEC-61754-7) and is therefore fully intermateable to any other MPO connector.

What is unique about the MTP connector?
A: The connector housing is removable: - Allows easy transition from male to female (gender change) Allows re-polish & re-work.

What are the benefits of the RoHS Directive?
A: The extraction and disposal of hazardous raw materials can cause damage to both the environment and to human health. The removal and or reduction of these types of materials at the production level will help reduce health risks associated with exposure and especially so for children and the elderly and pregnant women.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

What is affected by RoHS?
A: RoHS will affect anyone who manufactures in the European Union (EU) and sells electrical and electronic equipment under their own brand. It will also affect resellers in the European Union (EU) who sell products under their own brand or products produced by other suppliers.
