      ST Connectors

      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

    • Network Cable is Unplugged

      Network Cable is Unplugged

      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

    • Wavelength Division Multiplexing

      Wavelength Division Multiplexing

      Wavelength Division Multiplexing (WDM) is a technology found in fiber optic communications. WDM uses a single fiber to transmit multiple optical signals. It does this by breaking up the signal into different frequencies or wavelengths of color. The various wavelengths indicate that different amounts of data are being transmitted simultaneously. This results in an increase

    • RG-6

      RG-6

      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,

    • Subscriber Connectors (SCs)

      Subscriber Connectors (SCs)

      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

    • 568B

      568B

      568B, or more formally EIA/TIA 568B, is one of the International standards which include the definition for how the pins or wires in a RJ-45 cable are arranged or terminated. The termination of the cable can occur at several locations which include an individual cable connecting a computer to an Ethernet port, the ending socket

    • Multilayer PCB

      Multilayer PCB

      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

    • MTRJ Connectors

      MTRJ Connectors

      An MTRJ connector is a type of fiber optic cable that has an endpoint similar to the RJ-45 connector endpoint found in Ethernet connections. MTRJ connectors are designed to snap into the Ethernet port of a computer, modem, or wireless router and provide that computer or network with extremely fast data transfer rates. MTRJ connectors

      What is a Rollover Cable?

      A rollover cable is a network cable that connects a computer terminal to a network router’s console port. It is also referred to as a Cisco console cable and is normally flat and light blue so as to distinguish it from other network cable types. The pin-outs on one end of the cable are reversed
