The NDL7408P Series is a 1310 nm laser diode coaxial

module with single mode fiber. It has a strained Multiple

Quantum Well (st-MQW) structure and a built-in InGaAs

monitor photo diode. It is recommended for junction or access

network systems. The series is available in two types of output

power: 1.0 mW and 0.2 mW.
