mm Coaxial DFB Laser Module
GENERAL DESCRIPTION
The OL4492L, OL5492L/A, and OL5492L/B are MQW-DFB laser diode coaxial modules with
optical isolator and single-mode fiber pigtails. These modules are optimal light sources for
WDM supervisory channel in SDH system with optical in-line amplifier.
FEATURES
Single-mode fiber output: Pf=2 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
WDM supervisory channel in SDH system with optical in-line amplifier
