PRODUCT INFORMATION
840nm
1A440
VCSEL Laser Diode
Datacom, General Purpose
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.
