OL4128N-180
High-Power Laser Diode Butterfly Module
INTRODUCTION
Oki Semiconductor's OL4128N-180 is a 180 mW, 1480-nm, high-power laser diode and is available in a
14-pin "butterfly" package designed for high-performance fiber-optic applications. The OL4128N-180
diode has a built-in thermo-electric cooler, thermistor, and isolator, and has a single-mode fiber pigtail.
The OL4121N-180 diode can be used as a pumping source for Er- (erbium) doped fiber-optic amplifiers
in Dense Wavelength Division Multiplex (DWDM-EDFA) systems and long-haul terrestrial networks.
