There are many broadband Internet access methods. For enterprises, ADSL and optical fiber are currently popular. The full name of ADSL is an asymmetric digital user line. It is a popular broadband Internet access method and a technology that provides broadband data services through copper telephone lines. Optical fiber is short for optical fiber. Optical
In various technical means to achieve broadband access, the optical fiber access network is the most suitable for future development solutions, especially the ATM Passive Optical Network (ATM-PON) it is almost an economical and effective way to integrate broadband access. Outside China, china Southern Bell, France Telecom, British Telecom, CNET, Japan NTT, Germany Telecom, KPN, SwissCom, SBC, Telecom Italia CSELT and other international institutions h
Wiring system in the link floor of the trunk, due to the number of small, currently widely used multimode quartz fiber, and in the horizontal direction, there is not a suitable medium can not only provide enough bandwidth, but also has both a convenient installation, low cost, strong anti-interference ability and so on. The new fiber-optic networks with plastic optical fibers (POF) have all the advantages.
Introduction
In recent years, with the rapid development of Internet and information technology, people on the capacity of communication, transmission rate of higher requirements, now to the basic transmission of the physical layer of the media, in the information high-speed access to the electronic devices, resulting in the so-called "bottleneck", and as the network continues to extend, Anti-electromagnetic interference of the network in special place, anti-radiation, security and confidential
In the past two years, with the decrease in optical fiber costs and the wide application and upgrade of 1000Base and 10G Ethernet, optical fiber communication has gradually become an important part of LAN cabling and FTTx network construction. Due to the electromagnetic interference immunity of optical fibers, we do not need to consider the location Design of electromagnetic radiation devices such as power
