network cable disconnected

The access network system is widely used and has been well developed in various fields. It also plays an important role in cable TV return. After more than 20 years of development, China's cable TV network line is now more than 3 million kilometers in length, the optical fiber trunk line reaches 0.26 million kilometers

If you want external devices to access the local website, use the network cable to access the network connected by the route. if you want to ask a non-wireless network adapter, the local server will be connected by a wireless network card, an external device can access a loc

Ask a question, the local server, with the wireless network card network, the external device can be automatically generated by IP access to the local site, and through the network cable routed through the network, IP becomes 192.168 ... , the external access is not, how to

With the rapid development of broadband multimedia service and optical fiber communication technology, optical fiber communication technology has been used more and more widely in the access network. In the past, optical fiber network is mainly to meet the needs of transmission network construction, access to the layer of fiber optic
