SA Photonics has launched the first 'all optical switch' called Compact Scalable Matrix Optical Switch (COSMOS), specifically designed and developed for communication networks related to space.
SA Photonics introduces optical switch for space-based communication networks
COSMOS serves as a platform for satellite-based optical communication networks that contribute to lower crosstalk and increased bandwidth when compared to radio frequency (RF) communication.
The CEO of SA Photonics, Jim Coward sayid that the higher bandwidth of satellite communication systems has been provided by the COSMOS switch. The optical communication mesh networks across space and within satellites can also be achieved using the COSMOS switch. It is a unique all optical switch that can accomplish the space qualification testing.
COSMOS is a modular architecture that was specifically designed to endure extreme environmental conditions in space such as complex temperatures and radiation. It is capable of complying with any latest satellite and requires only minimal power for satellite applications. COSMOS employs a solid state switching mechanism derived from readily available integrated components. This facilitates the benefits of COSMOS such as zero power switch latching, lower insertion loss, simple integration into communication sub-systems and zero drift for extended operation.
At the test, COSMOS achieved a number of results based on its performance, including vibration of 19.1Grms all axes, average switch speed up to 15 ms, switch component radiation tolerance of 150 kRad Gamma, 150 kRad Proton, average insertion loss measuring 1db, Pyroshock from 10-10,000 hz 2 to 865g's, and temperature cycling ranging from -20°C to 700°C
Under a Small Business Innovation Research (SBIR) contract, SA Photonics developed the COSMOS for the U.S. Air Force.
