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 Fiberoptic Amplifiers in Dense Wavelength Division Multiplex (DWDM-EDFA) systems and long-haul terrestrial networks. FEATURES High power output: Pf=120 mW (OL4121N-120) Pf=140 mW (OL4121N-140) 14-pin “butterfly” package Single-mode fiber Built-in isolator Includes photodiode for power monitoring Built-in thermo-electric cooler (TEC) APPLICATION WDM/DWDM systems Erbium-doped fiber amplifier Regener...
