This Vertical Cavity Surface-
Emitting Laser is designed for Fibre
Channel, Gigabit Ethernet and ATM
applications. For eye safety, the opti-
cal power is attenuated to comply
with IEC Laser Class 1 requirements.
Note 1: Fiber: 50/125 Graded Index, NA=0.2 or 62.5/125 Graded Index, NA=0.275.
Note 2: Complies with laser Class 1 when operated at max 12 mA; Class 3 above 12 mA.
Class 1 Laser Product
The chip is isolated from the case.
