Optical transmitter having analog/digital mixed-mode temperature compensation function

摘要: Disclosed herein is an optical transmitter having analog/digital mixed-mode temperature compensation function. The transmitter, when detecting the output power of a laser diode, which outputs logic levels “1” and “0” as signals, through monitoring photodiode, controlling bias current drive circuit to maintain at constant values, includes programs for modulation based on variation in temperature, configured such that digital control unit using programs, so operation can be adjusted only by modification distal unit.
