Fiber-optic Transceiver And Its New Development

Faced with the rapid development of information construction

, the demand for data, voice, images and other multimedia applications is increasing. Ethernet broadband access also has been mentioned more and more important position. At the same time, the fiber-optic communications with its advantages of large capacity of information, confidentiality, light weight, small size, relay, long distance transmission has been widely used. Fiber-optic transceiver is the use of this high-speed fiber optic transmission media a good solution to the problem of Ethernet transmission.

The Optical transceiver is a short distance twisted pair electrical signals and optical signals over long distances, the Ethernet media conversion unit, interchangeable in many places, also known as the photoelectric converter. Enterprises in the information technology infrastructure, usually pay more attention to routers, switches, and even the card for the node data exchange network equipment, but often overlooked medium convert the network core but essential equipment. Especially when some of the information required in a high degree of government institutions and enterprises in the data traffic, network construction need to directly connect to the backbone network of fiber optic transmission medium, the internal LAN transmission medium typically copper wire, to ensure that packets in the smooth transfer between different network media conversion equipment to become a necessity. The fiber optic transceiver includes three basic modules: optical media converter chip, the optical signal interface (integrated optical transceiver module) and signal interface (RJ45), with network management functions include network management information processing unit.

The development of Fiber Optic Transceiver increases rapidly as the demand for network capacity, operators are increasing demand for network management, the continuing escalation of the Ethernet transmission speed, optical transceiver device types and complexity at an alarming rate . Due to the decline in the cost of optical fiber technology and capacity requirements increase, many telecommunications companies, local governments, and even large enterprise groups has begun to fiber-optic technology used in a Metropolitan Area Network (MAN) applications. Thus, once confined to the long-distance and high-end backbone network fiber-optic link technology is now available throughout every corner of the network facilities. However, the rapid increase in the number of applications of the fiber link also led to a wide variety of sometimes conflicting fiber optic transceivers will usher in high-speed development, according to the authoritative market research agencies predict 2014 40Gbps/100Gbps Ethernet transceiver market revenue will reach $ 545 million, of which 2/3 of sales revenue from the 40Gbps modules. And the 40G/100G product standards will be completed in mid 2010, when new products enter the market, the 40G/100G module development momentum will become increasingly apparent. 40/100 transceiver products supplier in the standards development, such as Avago Technologies, Finisar, Opnext and Sumitomo, the market in the future development plays an important role.
