      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

    • RG-59


      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

    • Multi Mode Fiber

      Multi Mode Fiber

      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)

      UTP (Unshielded Twisted Pair)

      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

    • Plenum Cable

      Plenum Cable

      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

    • ST Connectors

      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

    • 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-8


      RG-8 is a 50-ohm coaxial cable that is used for radio transmission (for instance in amateur radio or CB). Recently, they have become an integral part of computer networks, as they can increase connectivity. One of the first things that someone will notice about RG-8 cables is that they are huge when compared to other

    • Attenuation


      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
