Description

VCSEL module, TOSA(Transmitter Optical Sub Assembly) consists

of reliable 850nm VCSEL, back monitor PIN PD and plastic SC or

LC receptacle. The power monitor PD can be used with appropriate

feedback control circuitry to set a constant power level for each

VCSEL. The parts of plastic SC or LC receptacle are actively aligned.

This module guarantees high coupling efficiency, high slope efficiency,

low operating current and low tracking error over wide temperature

range(0℃ to +85℃) and provides high optical performance.
