Fiber optic patch panel, also known as the fiber distribution panel, is used mainly in fiber optic cable management. It helps network technicians in minimizing the clutter of wires when setting up fiber optic cables. It terminates the fiber optic cable while providing access to the cable’s individual fibers for cross connection. They are also …
A printed circuit board (PCB) is a thin board "printed" with electrical wires and made from fiber glass or similar material. PCBs are commonly used in computer devices such as motherboards, network interface cards, and RAM chips. They are relatively cheap and quite fast. When the PCB is fabricated with several layers placed over one …
The RG-59 cable is a type of coaxial cable that is used to generate low-power video connections. The cable works on two conductors that are based on a single common axis. It is also used for RF signal connections. The RG-59 cable conducts video and radio frequencies at an impedance of around 75 ohms. The …
Coaxial cables are necessary for rooftop antennas and dish antennas in order to provide crystal-clear sound and audio input. RG-11 bands typically have 75-ohm wires made of copper. Polyethylene dielectric makes sure that there is minimal loss of picture and sound while the antenna receives audio or video feeds. Most users of the RG-11 have …
Multi-mode fiber is a type of fiber optic cable which is thick enough for light to follow several paths through the code. Multi-mode fiber is best suited for use in short lengths, such as those used in Local Area Networks (LANs) and Storage Area Networks (SANs). Multi-mode fiber comes in two standard widths, 62.5 micron …
UTP (Unshielded Twisted Pair) is a regular copper wire that joins many home and many business computers to the telephone company. UTP is the most common form of twisted pair wiring, because it is less expensive and easier to work with than STP (Shielded Twisted Pair). It is used in Ethernet 10Base-T and 100Base-T networks …
An Ethernet crossover cable can be used to directly connect two network devices through Ethernet. These can either be single computers or they can be networks. Ethernet crossover cables are commonly used for temporarily networking two devices in the absence of a network router, switch, or hub. The principle is the same, but the connection …
Cat 3, short for Category 3, is a UTP (Unshielded Twisted Pair) cable designed to carry voice and data up to 10 Mbps (mega bits per second), with possible transmission frequencies up to 16 MHz. Cat 3 cable is part of a family of copper cabling standards defined jointly by the Electronic Industries Alliance (EIA) …
The plenum is hidden space within a building which is used for HVAC (Heating, Ventilation, and Air Conditioning) and to run cables. Plenum space is normally above a suspended ceiling or under a raised floor. Buildings without plenum spaces will have cabling and HVAC ducts within plain view. The plenum space is normally used to …
The ST (Straight Tip) connector is a fiber optic connector which uses a plug and socket which is locked in place with a half-twist bayonet lock. The ST connector was the first defactor standard for fiber optic cabling. It was first developed by AT&T. ST connectors were leading connectors in the late 80s and early …
