OL592L,OL5492L

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
