The CWDM(Aspherical Lens) TO LD laser diodes are uncooled multi-quantum-well DFB (Distributed Feedback) laser diodes for 2.5Gbps and 10Gbps transmission at 1310/1490/1550nm.
The laser diodes are packaged in a standard TO56 coaxial package with a photodiode for optical power monitor. Among these laser diodes, four products at 1270nm, 1290nm, 1310nm and 1330nm are suitable for 10Gbps transmission. The products are Telcordia GR-468 qualified, and in compliance with RoHS directives.
