Optical transceiver, is a short twisted-pair cable signals and long-distance optical signal exchange Ethernet transmission media conversion unit, in many places is also called "Fiber Converter. Products commonly used in Ethernet cable cannot cover, must use of optical fiber to prolong the transmission distance to the actual network environment, and usually located in broadband intracity networks of the access layer applications. At the same time help the optical fiber last kilometer lines connected to intracity networks and the more the outer layer of network also play a large role.
Informationization construction by leaps and bounds, people for data, speech and image multimedia communication demand increasingly vigorous, Ethernet broadband access way therefore mentioned a more and more important position. However, the traditional category five line cable will only Ethernet signal transmission 100 meters and on the transmission distance and coverage has already can not adapt to the need of the actual network environment. Meanwhile, optical fiber communication with its information capacity big, the secrecy good, light weight, small volume, WuZhongJi, the transmission distance advantages of long a wide range of applications, optical transceiver exploits the fiber this high-speed medium good solved Ethernet in transmission problems. In some larger scale of enterprises, the network construction for direct use of optical fiber transmission medium build backbone, and internal LAN transmission medium is commonly wire, how to realize the LAN connected with the fiber optic network? This needs in different port, different linear, the conversion between different fiber and ensure the link quality. Optical transceiver, will appear twisted-pair signals and light signals converts mutually, insure the packets in two network between smooth transmission network, and it will limit the transmission distance from copper wire of 100 meters expanded to 100 km (single-mode optical fiber). Enterprise in carrying on the information infrastructure, we usually pay more attention to the routers, switches and interfaces, etc for node data exchange network equipment, but often ignored media translations this kind of network core essential equipment. Especially in some requirements informatization degree is high, data flow larger government institutions and enterprises, the network construction need when connected to directly on of fiber-optic transmission medium, and the backbone enterprise internal LAN transmission medium for wire, ensure general packet in different network media translations between smooth transmission equipment become essentials.
Optical transceiver application
Optical transceiver normally used in Ethernet cable cannot cover, must use of optical fiber to prolong the transmission distance to the actual network environment, at the same time help the optical fiber last kilometer lines connected to intracity networks and the more the outer layer of network also play a large role. A optical transceiver, also need to will system from copper wire for upgrading to optical fiber, but lack of funds, manpower or time of users provide a cheap scheme. In order to guarantee and other makers nic, Repeaters, hubs and switches of network equipments fully compatible, optical transceiver products must strictly comply with the maximum distance that 10base-t, 100Base - TX, 100Base - FX, IEEE802.3 and IEEE802.3 u etc Ethernet standard. In addition, in the EMC preventing electromagnetic radiation aspects should comply with the FCC Part15. Nowadays due to the major domestic operators are to build community nets, campus network and enterprise nets, so the dosage of optical transceiver product also is rising ceaselessly, in order to better satisfy the access network construction needs.
Optical transceiver basic features:
1. To provide ultra-low delay the data transmission.
2. The network protocol are completely transparent.
3. Using special ASIC chip realize data speed forwarding. Programmable ASIC will multiple functions to focus on a chip, it is simple in design, high reliability, power consumption etc, can make the equipment to get higher performance and lower cost.
4. Frame type equipment can provide hot pull interpolation function, easy to maintain and uninterrupted upgrade.
5. Can network equipment can provide network diagnoses, upgrades, a status report, abnormal situation report and control functions, can provide the complete operational log and alarm log.
6. Equipment is used more 1 + 1 power design, support power supply voltage, realize extra-wide power protection and automatic switching.
7. Support exceed wide range of operating temperatures.
8. Support the complete transmission distance (0 ~ 120 kilometers)
