1. DESCRIPTION
The OL4450L-2-Wnnn, OL4451L-2-Wnnn, OL4453L-2-Wnnn, OL5450L-2-Wnnn,
OL5451L-2-Wnnn, OL5453L-2-Wnnn, OL6450L-2-Wnnn, OL6451L-2-Wnnn,
OL6453L-2-Wnnn series consist of an MQW-DFB laser diode, a monitor PD, a single-stage
optical isolator, a single-mode fiber and a coaxial package.
These modules are coaxial DFB Laser Diode Modules for CWDM 2.5Gbit/s transmission with
high power at high temperature.
