abstract: optical transceiver is a short twisted-pair electric signals and optical signals over long distances to swap the Ethernet transmission media conversion unit, also known as the photoelectric converter at many places.Enterprise based on the informatization construction, we usually pay more attention to routers, switches, and network card and so on network equipment for the node data exchange, are often ignored medium convert this kind of network core but indispensable equipment.
the function of optical transceiver fiber optic converters of the basic characteristics of optical transceiver
the role of the optical transceiver
optical transceiver commonly used in Ethernet cable can't cover, optical fiber must be used to extend the transmission distance of actual network environment, at the same time help the last kilometer in the fiber optic lines connected to the man and the outer also played a big role in the network.With optical transceiver, also for the need to upgrade to the optical fiber system from copper wire, but lack of money, manpower, or time the user provides a cheap solution.In order to guarantee card with other manufacturers, Repeaters, hubs and switches and other network equipment fully compatible, fiber optic transceivers products must strictly conform to the 10 base-t, 100 base - TX, 100 base - FX, IEEE802.3 u and IEEE802.3 Ethernet standard.In addition, in terms of EMC electromagnetic radiation shield should comply with the FCC Part15.Nowadays due to the major domestic carriers are vigorously construction of community network, campus network and enterprise network, therefore the dosage of the optical transceiver products are also constantly improve, in order to better meet the needs of the access network construction.
optical transceiver is a short twisted-pair electric signals and optical signals over long distances to convert the exchange of Ethernet transmission media unit.Commonly used in Ethernet cable can't cover, optical fiber must be used to extend the transmission distance of actual network environment.Mainly applied to some big companies and units, the construction of the monitoring network, optical fiber broadband and so on, to build long-distance network.
the structure of the optical transceiver
optical transceiver includes three basic function modules: medium photoelectric conversion chip, optical signal interfaces and electrical signals (RJ45), if equipped with network management functions include network information processing unit.The basic characteristics of optical transceiver
1.To provide low delay of data transmission.
2.Completely transparent to the network protocol.
3.Dedicated ASIC chip was adopted to realize data line speed forward.Programmable ASIC will be a number of functions to focus on a single chip, it has a simple design, high reliability, less power consumption, the device can get a higher performance and lower cost.
4.Frame type device can provide hot drawing function, easy to maintain and continuously upgrade.
5.Network equipment can provide network diagnosis, upgrade, status reports, abnormal situation report and control and can provide complete operation log and alarm log.
6.Equipment use 1 + 1 power supply design, more support super wide power supply voltage, to realize automatic power protection and switching.
7.Support the super wide working temperature range.
8.Support the complete transmission distance (0 ~ 120 kilometers)
