Light transmit-receive integrated module for myriad million light line terminal

Abstract

The invention discloses a 10 Giga optical link terminal optical transmitter and receiver integrated module, which includes a module optical interface, a module electrical interface and a kilo mega transmitter and receiver integrated optical component, also includes a 10 Giga optical transmitter component, and a 10 Giga transmitter drive circuit for driving the component. The 10 Giga transmitter drive circuit is composed of a signal transformation circuit, a laser drive circuit and a matching circuit, wherein the signal transformation circuit input terminal is connected with the electrical signal to be transmitted, the signal after being transformed by the signal transformation circuit is inputted into the laser drive circuit, the modulated signal, which is outputted from the laser drive circuit and is modulated by the matching circuit, is inputted into the electroabsorption modulator input terminal of the 10 Giga optical transmitter component, for driving 10 Giga optical transmitter component transmitter emitted light signal. The optical receiver and transmitter integrated module has signals with 10Gbps and 1.25Gbps down transmission rate, and signals with 1.25Gbps upward transmission rate, thereby realizing asymmetric transmission of upward signal and down signal for meeting the need of high-speed bandwidth.
