Q: What is the difference between backbone and horizontal cabling?

A: A horizontal cabling extends directly from the horizontal cross-connect in the telecommunication room to the workstations. A backbone cabling connects the telecommunications room with outside services, or connects telecommunications rooms together, or between buildings.

Q: What is structured cabling?

A: Structured cabling is a building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements called subsystems. These subsystems are the Work Area, Horizontal Cabling, Telecommunications Room, Backbone Cabling (Riser), Equipment Room, and Entrance Facility. A structure cabling can have a cabling infrastructure based on optical fiber, copper or a combination of both media.

Q: What is Return Loss (Fiber Optic)?

A: The Return Loss is the loss of signal power resulting from the reflection caused at a discontinuity in an optical fiber. This discontinuity can be a mismatch with the terminating load or with a device inserted in the line. It expressed in decibels (dB).

Q: What is Insertion Loss (Fiber Optic)?

A: The Insertion Loss is the loss of signal power resulting from the insertion of a device in an optical fiber and is express in decibels (dB).

Q: What are MPO and MTP?

A: MPO has been designed by NTT for the MT ferrule. These connectors are fully compliant with IEC-61754-7 and TIA-604-5.

Q: What is Keystone?

A: Keystone is the term use to define the standard rectangular profile in connectors and jacks, patch panels, faceplates, surface mount boxes and other outlets that connect different part of a network together. They are interchangeable between different Keystone product manufacturers.

Q: What is the difference between 568A and 568B wiring scheme?

A: T568A and T568B are both wiring schemes used today for terminating pairs in networks. It is important to ensure that the workstation connectors and patch panels are wired to the same pattern. There is no difference in performance between the two standards as long as the same scheme is used across the cabling system. T568A wiring scheme is widely used in Canada in contrast with the USA where the T568B is favored.

Q: What is the difference between the small foot print and regular foot print BNC connectors?

Wirewerks’ small foot print BNC connector is a 50 Ohms and is for analog video applications. Wirewerks regular foot print BNC connectors is a 75 Ohms and is for digital video applications

Q: Can Wirewerks modular connectors CAT5e run up to 350MHz?

A: The Wirewerks CAT5e modular connectors are capable to run up to 350MHz even through there is no standard requiring to run at that level. Nor is there any performance requirements established at that frequency.

Q: What does USOC means, and how the connections are wired?

A:USOC’s expanded acronym is Universal Service Ordering Code. This an old Bell system identifying a particular service or equipment offered under tariff. USOC specifies the order in which wires are connected in a 4, 6, 8 position modular connector/jack.

Q: What is the difference between Keywerks patch panels and Wirewerks 110-Type patch panels?

A: Keywerks patch panels are a series of independent Keystone jack/connectors each to be terminated individually. Wirewerks 110-Type patch panels present modular blocks of 6 unified jacks with 110-type termination block at their rear.
