  • Composite grounding communication optical cable

    Composite grounding communication optical cable

    An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and telecommunications. An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire. The. HistoryAn OPGW cable was patented by BICC in 1977 and installation of optical ground wires became widespread starting in the 1980s. In the peak year of 2000, around 60,000 km of OPGW was installed worldwide. Asia, especially. Several different styles of OPGW are made. In one type, between 8 and 48 glass optical fibers are placed in a plastic tube. The tube is inserted into a stainless steel, aluminum, or aluminum-coated steel tube, with some slack lengt.

  • Communication between two optical port switches

    Communication between two optical port switches

    Can two switches with fiber ports be directly connected through fiber ports? The answer is yes. Moreover, when it comes to bandwidth, no currently available technology is better than single-mode fiber. It can provide significantly higher bandwidth and carry more data. Switch optical port intercommunication means that the optical fiber ports of two switches are connected to each other to achieve the purpose of network connection. The connection between two or more Ethernet switches in a certain way (Uplink port, etc. Optical switching is the process of controlling the destination of individual optical information signals. We have existing core switch model C9300-NM-8X, we are extended small office same building in different floor.
