In the past, two main termination specifications were used. One was for UTP data cable infrastructure and the other for phone cable infrastructure. Today, structured cable systems are in use. 568A is one such standard. 568A is a standard for the pin arrangements of RJ-45 connectors on Unshielded Twisted Pair (UTP) wire. The cryptic number …
An Ethernet fiber media converter is a device that allows a connection to be made between an Ethernet and a fiber optic cable. This type of connection is important in situations where both cable types are used in a single household or office. Because telephone companies often use fiber optic cables to deliver telephone and …
DWDM stands for Dense Wavelength Division Multiplexing. DWDM is a technology used to increase the capacity of fiber optics that results in faster transfers of data. What are fiber optics? Fiber optics are very thin and small fibers that are used to transmit data and light throughout a computer and network. How does DWDM affect …
RG-6 cable is one of the more common types of coaxial cables used for commercial and household purposes. The term RG-6 is a generic label that can be used to describe a whole range of cable designs. In fact, all cable designs described under RG-6 may well differ from one another in center conductor composition, …
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 Subscriber Connector (SC) is a fiber optic connector with a push-pull latching mechanism that provides quick insertion and removal while ensuring a positive connection. The SC is also available in a duplex configuration. It has a benefit in keyed duplex capability to support send/receive channels. This connector is commonly used for most modern network …
When an error message saying, “Network cable is unplugged” is displayed, it generally means that the computer can detect that there is an ASDL and/or Cable Connection pre-configured on the computer, but an Ethernet cable and/or a cable that is supposed to be plugged into the modem is unplugged. In the case that all of …
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 …
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 …
Attenuation is a reduction in signal strength over distance. Attenuation is a common problem of telecommunication cables that causes a decrease in data speeds on longer cables. Attenuation is also known as “loss” and can be countered by data repeaters and amplifiers. While attenuation is a problem for long cables, short cables do not usually …
