Fiber Optic Transceiver is a device indispensable in network data transmission, then what is the fiber optic transceivers, fiber optic transceivers have what composed it, fiber optic transceivers play what role in the data dissemination process?
Fiber optic transceiver includes three basic functional modules: the photoelectric media conversion chip, optical signal interface (optical transceiver module) electrical signal interface (RJ45), if equipped with a network management functions include network management information processing unit.
Fiber Transceiver, is a short distance twisted pair electrical signals and optical signals over long distances swap the Ethernet transmission media conversion unit, also called Fiber Optic Converter in many places. The general applicatioin can not be covered in the Ethernet cable, you must use optical fiber to extend transmission distance of the actual network environment, and is usually located in the broadband metropolitan area network access layer application; same time help last mile fiber line is connected to the city area network and the outer layer of the network has also played a huge role.
In some large enterprises, network construction directly when using optical fiber as transmission medium build backbone network, and internal LAN transmission medium is commonly copper wire, how to achieve LAN with fiber optic backbone connected? This needs in different port, different linear, different optical fiber links between conversion and ensure quality. The emergence of the optical transceiver, will double stranded wire electrical signal and light signal is mutual conversion, ensure the data packet in two network room smooth transmission, at the same time it will network transmission distance limit from copper wire of 100 meters expanded to more than 100 km (single-mode fiber).
The basic characteristics of fiber optic transceivers:
1.Is completely transparent to the network protocol
2.Ultra-low-latency data transmission
3.Support ultra-wide operating temperature range
4.Dedicated ASIC chip data wire-speed forwarding. The programmable ASIC concentrated in a number of functions on a single chip, has a simple design, high reliability, less power consumption, enabling the device to get higher performance and lower cost.
5.Managed devices can provide network diagnostics, upgrades, status reporting, exception reporting and control functions, provide a complete operating log and alarm log.
6.The rack device provides hot-swappable features, ease of maintenance and seamless upgrade
7.Support the full range of transmission distance (0~ 120 km)
8.The device is the use of the 1 +1 power supply design, support wide power supply voltage, power protection and automatic switching.
