Abstract
A transmitter optical module that implements with two or more laser diodes (LDs) therein is disclosed. The LDs are mounted on a common sub-mount independent of driving circuits and driven by the driving circuits in the shunt-driving mode. The cathode of the LDs are independently, namely, isolated from the ground of the neighbor LDs, connected to the ground within the driving circuits but floated from the chassis ground.
