Optical fiber transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted pair electrical signals and long-distance optical signals. It is also called fiber converter in many places. The products are generally used in the actual network environment where Ethernet cable cannot cover and optical fiber must be used to extend the transmission distance, and are usually located in the access layer application of broadband man; For example, high-definition video image transmission of monitoring safety engineering, etc.

In the Internet era, we use optical signals for information transmission. Optical communication is a communication mode with light waves as carriers. Maybe you don't know what optical communication is, but you must be using optical communication. For example, when you make a phone call or open your browser to browse the web, you are already using optical communication. Optical communication has been integrated into everyone's life.

OTN is a transmission network based on wavelength division multiplexing technology and organizing the network in the optical layer. It is the next generation backbone transmission network. OTN is a new generation of "digital transmission system" and "optical transmission system" standardized through a series of ITU-T recommendations such as g.872, G.709 and g.798. It will solve the problems of poor scheduling ability, weak networking ability and weak protection ability of wavelength / sub wavelength services in traditional WDM networks. A series of problems are solved through a series of traditional OTN protocols. OTN spans the traditional electrical domain (digital transmission) and optical domain (analog transmission). It is a unified standard for managing electrical domain and optical domain.
