1.55
mm Coaxial DFB Laser Module
GENERAL DESCRIPTION
The OL592L, and OL5492L are MQW structured, 1.55 mm coaxial DFB laser modules with
single-mode fiber pigtails. Having a good side-mode suppression ratio and a wide operating
temperature range, these devices are optimal light sources for high-capacity long-haul
transmission systems.
FEATURES
Single-mode fiber output: Pf=1 mW
Side mode suppression ratio: 30dB
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
