The network ptach cord

Fiber optic transceivers and switches are very important in Ethernet transmission, but they are different in function and application. So, what is the difference between a fiber optic transceiver and a switch? This article explains in detail for you.What is the difference between a fiber optic trans

Optical access network is the optical transmission medium access network, instead of copper wire, used for access to every home.Optical access network An optical access network generally consists of three parts: optical line terminal OLT, optical network unit ONU, and optical distribution network OD

1. The optical port is low or there is no light, resulting in the abnormal operation of the user's optical transceiver. At this time, the signal lamp cannot receive optical signals from the optical cable or the power of optical signal transmission is too low, resulting in the abnormal handshake betw

To the ONU this problem, many friends may be relatively unfamiliar, do not know why in the installation of network cable will be more than a ONU, then what is the ONU?What's the use of ONU alone?Let's go to understand the next

For ONU is optical fiber into the cable network access to the device, commonly known as for modem, in fact, in today's OUN had light from the early single function, not only has the function of modem, also has the function of the router, but generally if the light above the ONU with the function of

Are the optical fibers in optical cables really afraid of water?When the optical cable is formed into a cable, there are two protection requirements for the optical fiber: one is that the optical fiber is less stressed; the other is that the optical fiber should be waterproof.,The outermost layer of

Bundled pigtails, also known as pigtail bundles, multi-core connectors, only have a connector at one end, and a broken end of an optical fiber at the other end, which is connected to other optical fiber cores by fusion splicing, and often appears in the optical fiber terminal box. Used to connect op
