1.55 mm High-Power Laser-Diode DIP Module
GENERAL DESCRIPTION
The OL5201N-25 and OL5204N-25 are 1.55 mm, extremely high-power laser-diode DIP modules
with single-mode fiber pigtails. The Multi-Quantum-Well (MQW) structure laser diodes
achieve a single-mode fiber output of over 25 mW. The modules are optimal light sources for
optical measuring instruments and other systems that require high-power.
FEATURES
• High output power: Pf=25 mW
• Single-mode fiber
• Hermetically-sealed,14-pin Dual-In-line Package (DIP)
• Includes thermoelectric cooler for temperature control
• Includes monitor photodiode for power control (OL5201N-25)
APPLICATIONS
• Optical measuring instruments
• OTDRs
