OPTICAL MODULE, BURST TRANSMISSION METHOD THEREOF, LASER AND OPTICAL NETWORK SYSTEM

摘要

An optical module, a burst transmission method of the optical module, a laser and an optical network system are provided by the embodiments of present invention. By adding a switch in the transmitter of the optical module, when the burst enable signal inputted from the control end of the switch is invalid, the switch is switched to a bias mode to provide a bias current for the optical module; by improving the prior burst transmission method of the optical module and the structure of the laser, underpower caused by the usage of seed source by the prior laser is solved, and it is ensured that the data is modulated and transmitted rapidly if there exists data to be transmitted; and if not, a lower bias current is provided to the optical module to reduce the time for restarting burst and improve the transmission efficiency of the entire optical network system.
