Commercial-off-the-shelf photonic components designed for datacenter or industrial applications do not typically satisfy the environmental ruggedness requirements of aerospace applications. In order to reduce costs and schedule risk for insertion of photonic components into these harsh-environment applications, we developed ruggedized fiber-optic transceiver and optical amplifier modules to support both on-board fiber-optic datalinks as well as inter-satellite free-spaceoptical (FSO) communications systems. Parallel-optical transceiver components were developed to support data rates up to 25 Gbps per fiber, for high-density spacecraft onboard datalinks over the -40C to +85C temperature range, based on a novel hermetic opto-electronic hybrid construction. These components utilize MTP 12-fiber optical and high-speed electrical connectors for ease of installation and removal and survive extremely high levels of shock and vibration. The extremely efficient heatsinking the lasers, photodiodes and integrated amplifier circuits permits operation up to 85C case temperature while maintaining low device junction temperatures required for high reliability. Dense-wavelength-division-multiplexed (DWDM) transceivers were also developed to support multi-rate FSO systems from < 1 Gbps to 12.5 Gbps for FSO links on 60 ITU grid wavelengths. The transceivers permit user optimization of link parameters to attain highest performance in amplified systems. High-power Erbium-Ytterbium booster optical amplifiers up to 5W output power, and low-noise Erbium pre-amplifiers, in the 1540-1565 nm wavelength band, were also developed and tested in a space vacuum environment. We performed reliability and environmental testing to demonstrate that these modules meet or exceed many of the requirements of space applications. In this presentation we will show performance characteristics and results of reliability and environmental tests for these transceiver components.
