Reliability Testing of 28Gbps/channel Fiber Optics Transceivers for Space Applications

Smiths Interconnect manufactures fiber optic multi-channel parallel optical transceivers. The transceiver product families consist of 4-channel and 12-channel versions with each channel capable of supporting data rates of up to 28Gbps independently. The optical interface is an integrated industry standard 1x12 MT ferrule optical fiber interface. The transceiver modules provide excellent optical intra-satellite high-speed communication links with a single +3.3V power supply and case operating temperature range from -40°C to +85 °C. The devices are extremely light weight (3.0g), low power consumption and resistant to radiation effects and Electro-Magnetic Interferences (EMI). The transmitter channels are based on 850nm wavelength Vertical Cavity Surface Emitting Lasers (VCSELs) offering the best possible performance stability over a wide range of temperature without the need for power-hungry temperature controllers. In this talk, results from space and environmental qualification tests will be presented and more specifically, single event effect (heavy ions), total ionizing dose (gamma rays) and total non-ionizing dose (proton) radiations, live vacuum thermal cycling (TVAC) and outgassing. In addition to space qualification tests, further environmental qualification tests were completed to validate the mechanical integrity of the product, including live random vibration, mechanical shock, thermal shock, rapid decompression, temperature cycling, lifetime, and damp heat tests. The transceivers are built on the same manufacturing platform used for Smiths Interconnect's 10Gbps transceivers which are currently flying in space. Based on space qualification and environmental qualification test results, Smiths Interconnect's 28Gbps/channel transceivers have been proven to be well designed for the harsh space atmospheric environment and to be radiation tolerant.
