Optical transceiver and its new development

Face informatization construction make a spurt of progress, people for data, voice, image and other multimedia applications demand increases increasingly, Ethernet Broadband access way is therefore referred to a more and more important position. At the same time, optical fiber communication with its large information capacity, confidentiality good, light weight, small volume, no relay, long distance of transmission has been widely applied, fiber optic transceivers is the use of optical fiber the high-speed transmission medium well solves the problems in the transmission of ethernet.

Fiber optic transceivers is a short distance of the twisted pair telecommunications and long distance optical signal exchange Ethernet transmission media conversion unit, in many places, also known as the photoelectric converter. Enterprises in the information technology infrastructure, typically pay more attention to the router, switch and network card for node data exchange network equipment, but often neglect the medium converting the network core but essential equipment. Especially in some of the requirements for a high degree of information, the data flow of large government agencies and enterprises, network construction needs to directly connected to the optical fiber as the transmission medium of the backbone network, while the internal local area network transmission medium for copper wire, ensure that the data packets between different network smooth transmission medium conversion equipment necessary. Fiber optic transceiver includes three basic functional modules: OEMC, optical signal interface ( optical transceiver module ) and the signal interface ( RJ45 ), if equipped with network management functions include network management information processing unit.

With the development of fiber optic transceivers on the network capacity demand increase sharply, operator for the requirement of network management is increasing, the Ethernet transmission speed upgrade, an optical transceiver type and complexity are developing at an amazing speed. Because the optical fiber technology and the decline in the cost of capacity requirements increase, many telecommunications companies, local government, even for large enterprise groups have begun to optical fiber technology used in city area network ( MAN ) application. Therefore, once confined to remote and high-end backbone network optical fiber link technology is now available throughout the network facilities at each corner of the. However, the rapid increase of the number of optical fiber link application also caused a wide variety, sometimes even conflicting fiber optic transceivers will usher in rapid development according to authoritative market research agencies forecast, 2014 40Gbps/100Gbps Ethernet </a> transceiver market sales revenue will reach 545000000 yuan, of which 2/3 sales revenue from the 40Gbps module products. Because 40G/100G product standard in mid 2010, when the new product will enter the market, 40G/100G module development momentum will be shown increasingly. While the standard before the 40/100 transceiver product suppliers, such as Avago, Finisar, Opnext and Sumitomo, the market will play an important role in the development.
