2B454
VCSEL Laser Diode
Datacom
T h i s Vertical Cavity SurfaceEmitting Laser is designed for Fibre Channel, Gigabit Ethernet, ATM and general applications. It incorporates a p h o t o d i o d e to monitor the optical power and allow for feedback control. For eye safety, the optical power is attenuated to comply with IEC Laser Class 1 requirements.
