Abstract

Embodiments of the invention provide an optical module and an optical signal output control method. The optical module comprises a laser source, a semiconductor laser amplifier, and a drive circuit of the semiconductor laser amplifier. The optical module further comprises a switching circuit of which one end is connected with the bias current output end of the drive circuit of the semiconductor laser amplifier, and a controller which is used for making the switching circuit connect the bias current output end of the drive circuit to the semiconductor laser amplifier after receiving an optical signal transmission instruction, and making the switching circuit disconnect the bias current output end of the drive circuit from the semiconductor laser amplifier after receiving an optical signal stop instruction. According to the technical scheme of the invention, the on time and off time of optical signal output of the optical module can be shortened greatly, and quick start and cutoff of optical signal output of the optical module is realized.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular, the present invention relates to an optical module and an optical signal output control method. Background technique [0002] Currently, a Passive Optical Network (PON) has been widely deployed as an optical access system. PON usually includes: an optical line terminal OLT (Optical Line Terminal) set at the central office, an optical network unit ONU (Optical Network Unit) set at the terminal, and an ODN (Optical Distribution Network, optical distribution network) connected between the OLT and the ONU. network). The OLT is usually provided with several optical modules, and the optical modules in the OLT are connected to the ODN through optical fibers for transmitting downlink optical signals or receiving uplink optical signals. An optical module is generally arranged in the ONU, and the optical module in the ONU is connected to the ODN through an optical fib...
