55 mm Coaxial DFB Laser Module
OL592L, OL5492L
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
