DESCRIPTION
The NDL7401P 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 and
access network systems. The series is also available in FC-
PC and SC-PC connectors.
