mm 2 mW Coaxial Module
GENERAL DESCRIPTION
The OL592N-2, OL597N-2, OL5492N-2, and OL5497N-2 are 1.55mm, MQW InGaAsP/InP laser-
diode modules with a 2mW output, pigtailed with single mode fibers. These modules are
optimal light sources for high-capacity long-haul optical transmission systems.
FEATURES
• Single-mode fiber output: Pf=2 mW
• Includes monitor photodiode for power control
• Wide operating temperature range
• Multi-quantum-well (MQW) structure
APPLICATIONS
• Optical transmission systems
• Subscriber loops
• Optical measuring equipment
