METHODS, OPTICAL TRANSMITTER, OPTICAL MODULE, AND OPTICAL COMMUNICATION SYSTEM FOR IMPROVING THE MONITORING AND/OR REPORTING ACCURACY OF A LASER TRANSMITTING POWER

摘要

Disclosed are methods, optical transmitter, optical module, and optical communication system for improving the monitoring and/or reporting accuracy of a laser transmitting power. In the methods, the output power of an optical transmitter is measured at 25℃ and at N individual temperatures to obtain N tracking error (TE) values corresponding to the N individual temperature values, then a lookup table covering an operating temperature range of the transmitter is created based on a line fitting process, wherein the line fitting process is created based on a one-to-one mapping relation between the TE values and the N individual temperatures. The transmitter output power is reported at an interface of the transmitter according to the TE value at the transmitter operating temperature in the lookup table. The present method and transmitter effectively improve the monitoring and/or reporting accuracy of the transmitter output power.
