This Vertical Cavity Surface-
Emitting Laser is designed for Fibre
Channel, Gigabit Ethernet, ATM and
general applications. It operates in
multiple transverse and single longi-
tudinal mode, ensuring stable cou-
pling of power and low noise.
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.
The chip is isolated from the case.
