Development of fiber optic transceivers and its new

Feb. 14, 2011 - PRLog -- First, the current fiber optic transceiver products is not enough intelligence. For example, when the fiber optical transceiver broken, the majority of the other side of the electrical interface products will still remain open, so the top equipment such as routers, switches and other remains or will continue to Electrical interfaces to the contract, resulting in data is not up. We hope that the equipment providers can be fiber optic transceiver automatically switches off when the light path DOWN, the electrical interface automatically upwards alarm, and to prevent the upper port to send data to the device to enable the redundant links to ensure Business is not interrupted. Second, fiber optic transceivers themselves should be better adapted to the actual network environment. In practical engineering, the use of fiber optic transceivers place mostly within the corridor or outside, the power supply situation is very complicated, which requires all manufacturers of equipment is best to support Wide supply voltage support to adapt to unstable power supply conditions. Same time, because there will be high in many parts of the domestic Super mild cold weather, lightning and electromagnetic interference impact is real, all of which transceiver the impact of all this outdoor equipment Very large, which requires equipment providers in the adoption of key components, circuit layout and structural design and welding must be carefully strict. In addition, network management control, the user mostly hope that all network devices through a unified network management platform to Remote management, fiber optic transceiver that is able to import the MIB database to the entire network management information database. Therefore, R & D in the network management information needed to ensure the standardization and compatibility. Fiber optic transceiver data transmission on the Ethernet cable meters to break the limitations of Nature, relying on the exchange of high-performance chips and large-capacity cache, in the truly non-blocking switching performance of transmission also provides a balanced flow, isolate the conflict and error detection functions to ensure data transmission security and stability of the high . Therefore, in a very long one Period of time, fiber optic transceiver products will continue to build the actual network is an integral part of, I believe the future will move toward fiber-optic transceivers high intelligence, high stability, network management, continue to develop low-cost orientation.
The face of the rapid progress of information technology, people data, voice, images and the increasing demand for multimedia applications, Ethernet broadband access are therefore referred to the increasingly important position. At the same time, its information capacity optical fiber communication, confidentiality Light weight, small size, no relay, and long transmission distance has been widely used, is the use of fiber optic transceivers that high-speed optical fiber transmission medium can solve the problem of Ethernet transmission.
Optical transceiver is a short distance to long distance twisted pair electrical signals and optical signals for transmission swap the Ethernet media conversion modules, in many places is also known as Media Converter. Enterprises in information technology infrastructure, they usually pay more attention to Routers, switches, network cards, etc. as well as data exchange for the nodes of network equipment, but often overlooked core of the network media conversion, but such non-essential equipment. Especially in a high degree of information required, the data flow of the larger government agencies and enterprises, network Directly on the building connected to the need for fiber optic backbone network for the transmission medium, and enterprise LAN transmission medium is usually copper, to ensure that data packets between different networks seamless transmission of media conversion equipment to become a necessity. Fiber optic transceivers include the three basic functions Module: Optical media converter chip, optical signal interfaces (optical transceiver module) and the signal interfaces (RJ45), if equipped with network management network management functions are also included information processing unit.

With the development of fiber optic transceivers to the rapidly increasing demand for network capacity, network operators manage the increasing demand, the continuing escalation of the Ethernet transmission speed, optical transceivers are the type and complexity of the development at an alarming rate . As optical fiber technology Cost reduction and capacity requirements increase, many telecommunications companies, local governments, and even large enterprise groups have begun to fiber-optic technology used in urban area network (MAN) applications. Therefore, once confined to remote and high-end fiber-optic backbone network link technology is Has been throughout every corner of the network infrastructure. However, the number of fiber link applications has also led to the rapid increase in variety, and sometimes even contradictory optical transceiver will usher in rapid development, according to market research firm forecasts the authority of 2014 40Gbps/100Gbps Ethernet Net transceiver market revenue will reach 545 million, of which 2 / 3 of the sales revenue from 40Gbps modules. As 40G/100G product standards will be completed in mid 2010, when the new products will enter the market, 40G/100G module development momentum will be at Interest emerged. 40/100 before the standard- setting supplier of transceivers, such as Avago, Finisar, Opnext, and Sumitomo, etc., the future development of the market plays an important role.
