Hight Temperature Operation 1.3 mm Laser-Diode Coaxial Module
GENERAL DESCRIPTION
The OL391N, OL392N, OL397N, OL3492N, and OL3497N are 1.3 mm, MQW InGaAsP/InP laser
diode coaxial modules with single-mode fiber pigtails. These modules are optimal light sources
for high-capacity long-haul optical transmission systems.
