Optical port self-adaptive Ethernet network fiber optical transceiver and self-adaptive approach thereof

Abstract

The invention provides an optical port self-adaptive Ethernet network fiber optical transceiver, comprising an electrical interface unit, an optical interface unit, an actinodielectric translation unit, a configuration unit, a detection unit and a resetting system; wherein the actinodielectric translation unit comprises an internal register, the detection unit and the configuration unit are electrically connected, the actinodielectric translation unit is electrically connected with the electrical interface unit, the optical interface unit, the configuration unit and the resetting unit respectively. The invention further provides the self-adaptive approach of the optical port self-adaptive Ethernet network fiber optical transceiver and provides the possibility of using fiber optical transceivers with different optical interface unit speeds in the same optical fiber link; the optical port self-adaptive Ethernet network fiber optical transceiver of the invention has wider application range than ordinary fiber optical transceivers, thus avoiding operating at low speed due to access to high-speed optical link; in addition, after the fiber optical transceiver at the other end of the optical fiber link is updated, namely the speed is increased, mutual communication among the fiber optical transceivers can still be carried out.

Description

【Technical field】 [0001] The invention relates to a network technology, in particular to an optical port self-adapting Ethernet optical fiber transceiver and an self-adapting method thereof. 【Background technique】 [0002] Ethernet fiber optic transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted-pair electrical signals (Ethernet data) and long-distance optical signals. Its main function is to extend the connection distance of Ethernet. Breaking the distance limitation that twisted pair can only transmit 100 meters. Ethernet fiber optic transceivers are generally used in actual network environments where Ethernet cables cannot be covered, and optical fibers must be used to extend the transmission distance if the distance is greater than 100 meters, and are usually located in the access layer application of broadband metropolitan area networks. [0003] Driven by the increasing demand for network bandwidth and the diversification...

Problems solved by technology

However, whether it is an optical switch or a high-speed transceiver, its optical interface is only fixed at 10M, 100M or 1000M, because the encoding methods of optical ports at different rates are different (100M is 4B / 5B encoding, 1000M is 8B / 10B encoding), so that two LANs with different optical port speeds cannot communicate with each other through optical fibers, which causes inconvenience in communication
