Abstract

The invention discloses a 40G CFP optical module for long-distance transmission, which mainly comprises an optical receiving unit, an optical transmission unit, a control unit and a power supplying unit, wherein the optical receiving unit is for converting the received optical signal into an electrical signal through a detector and outputting the electrical signal; the optical transmission unit is for converting the electrical signal at an interface unit into the optical signal to output through a modulation laser DML; the control unit is connected with the optical transmission unit, the optical receiving unit and the interface unit respectively for communicating with a host computer, intelligently controlling parameters and reporting the monitoring information; and the power supplying unit is for supplying power to the optical transmission unit, the optical receiving unit and the control unit, and controlling on / off of each unit. Through the optical module, the application requirement on long-distance (more than 40km) transmission of the CFP optical module at present can be well met.

Description

technical field [0001] The invention relates to an optical transceiver integrated module of optical communication transmission technology, in particular to a 40G CFP optical module used for long-distance transmission (above 40km). Background technique [0002] With the increasing transmission capacity in the communication field, it is difficult for traditional transmission technologies to meet the requirements of transmission capacity and transmission speed. In order to prevent serious shortage of broadband resources in the core network, operators and service providers plan a new generation of high-speed network protocols. is deployed. In order to meet the requirements of large-capacity network bandwidth, high-speed WDM transmission technology has become the focus of problem solving. The Institute of Electrical and Electronics Engineers (IEEE) has formulated IEEE 802.3ba, a unified specification for 40G and 100G for metropolitan area networks and access networks. [0003...
