High-Power Laser-Diode Butterfly Modules
INTRODUCTION
Oki Semiconductor's OL4121N-120/OL4121N-140 family of 1480-nm high-power laser diodes are avail-
able in a 14-pin "butterfly" package which is designed for high-performance fiber-optic applications. The
OL4121N-120 and OL4121N-140 diodes have a built-in thermo-electric cooler, thermistor, and isolator,
and have a single-mode fiber pigtail.
The OL4121N is available in two optional power levels: 120 mW or 140 mW. These laser diodes can be
used as a pumping source for an Er- (erbium) doped fiber-optic amplifier. The high power output of the
laser diodes in the OL4121N family supports the high-performance demands of Erbium-Doped Fiber-
optic Amplifiers in Dense Wavelength Division Multiplex (DWDM-EDFA) systems and long-haul terres-
trial networks.
