OL392L,OL3492L
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
