Paper Abstract

We present results from the development of a dual channel Optical Fiber Amplifier (OFA) that consists of two copropagating low noise EDFAs at 1565 and 1545nm. The two channels have separate outputs but can also be combined via an optical switch to a common output channel for an increased output signal power. The OFA produces up to 35dB gain at low signal input powers and a total of over 350mW optical signal power combined from both EDFA channels with a 5mW signal input. The OFA was tested with input signals between 0.1 – 20 mW over the C-band and with pump power varying from 0 – 100% of the maximum operating pump power. The OFA module has total mass of 583 g including all electrical and optical components, as well as optical and electrical bulkheads, and a total module volume of 430 cm3. The module was also radiation tested via gamma irradiation up to 100 krad TID, validating the robustness of the optical amplifier against RIA effects and its suitability for LEO and GEO satellite missions.
