OL3201N-40, OL3204N-40
1.3 mm High-Power Laser-Diode DIP Module
GENERAL DESCRIPTION
The OL3201N-40 and OL3204N-40 are extremely high power, 1.3 mm laser-diode DIP modules
with single-mode fiber pigtails. The OKI laser chips achieve single-mode fiber output of over
40 mW. These modules are optimal light sources for optical measuring instruments and other
systems that require high power.
FEATURES
• High output power (single-mode fiber output): Pf=40 mW
• Single-mode fiber
• Hermetically-sealed, 14-pin Dual-In-line Package (DIP)
• Includes thermoelectric cooler for temperature control
• Includes monitor photodiode (OL3201N-40)
APPLICATIONS
• Optical measuring instruments
• OTDRs
