Hi Eoin,
I like to discuss some of features and applications of a 1270 nm- 1610nm Series 18 Channels CWDM Laser Diode Modules:
FEATURES
Un-cooled 1270 nm – 1610nm DFB laser diode (LD) with MQW structure
High temperature operation without active cooling
Hermetically sealed active component
Single frequency operation with high side mode suppression ratio
Build-in high performance/speed InGaAs monitor PIN photodiode (PD)
For 9/125 mm SM fiber
PACKAGING
Fiber pigtailed with optional FC/ST/SC connector
Packaged in FC or ST Receptacle with fiber stub.
APPLICATIONS
Design for CWDM fiber optic networks
SONET OC-12/OC-48 / SDH /STM-4/STM-16
Gigabit Ethernet
Stable emitting source at specific wavelength
Thanks,
