What Is a Fiber-Optic Network?

An optical fiber network is a light transmission tool that uses the principle of total reflection of light in fibers made of glass or plastic to connect to a company or home or computer room. Use a switch or other terminal to convert to an ordinary RJ45 network cable and connect it to the computer, also called LAN. The switch or other terminal automatically assigns an IP. The internal network IP needs to be set in the terminal background. The default is automatic and no dialing is required.

FTTH (Fiber-to-the-Home) is the direction for the further development of fiber-optic communications, and it is recognized as an ideal broadband access network. So-called

The fiber is easily broken. The texture is brittle, the mechanical strength is low, the connection is difficult, the technical requirements are high, the shunting and coupling are not convenient, and the bending radius should not be too small. In addition, whether it is fiber optic cabling or fiber optic equipment, the price is still too expensive. ^[2]

According to theoretical calculations, the capacity of the wavelength windows of 1.3 micrometers and 1.55 micrometers commonly used in optical fiber communication is at least 25000 GHz. I naturally think of using multi-wavelength

Optical fiber access generally refers to the exclusive use of optical fiber at the access end. If an enterprise uses optical fiber to access the Internet, the internal network generally does not need to be changed. After the fiber is received by the operator, a key device is used here- ---- The photoelectric converter can convert the optical signal into an electrical signal after conversion. After it comes out, it is the RJ45 interface, which is the interface of our usual network cable. It can be directly connected to the company's router or switch. The public network ip can access the Internet normally. This device photoelectric converter is provided by the operator. ^[2]
