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.
FEATURES
Single-mode fiber output: Pf=1 mW
Side mode suppression ratio: 30 dB
Includes monitor PD for power control
Built-in optical isolator
Wide operation temperature range
Multi-quantum-well (MQW) structure
APPLICATIONS
Optical transmission systems
Optical subscriber loops
Optical measurement systems
