This Vertical Cavity Surface-

Emitting Laser is designed for Fibre

Channel, Gigabit Ethernet, ATM and

general applications. It incorporates a

photodiode to monitor the optical

power and allow for feedback control.

Note 1: Fiber: 50/125 Graded Index, NA=0.2 or 62.5/125 Graded Index, NA=0.275. An external glass

ball lens with 2 mm diameter is required.

WARNING: Laser Radiation, avoid exposure

to beam. Class 3B laser product, potential

eye hazard. Warning labels in each box.
