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
