1.3 mm Coaxial DFB Laser Module
GENERAL DESCRIPTION
The OL392L, and OL3492L are 1.3 mm coaxial DFB laser modules with single-mode fiber
pigtails. Having good side-mode suppression ratio in a wide operation temperature range,
these devices are optimal light sources for high-capacity long-haul optical transmission
systems.
