Celestia STS Optical Modem for Free Space Optical Communication

The Optical Modem is designed to be multi-standard compatible and can be in-field reconfigured. The system is 19” rack mountable and is designed for use both in optical communication ground stations and in test / lab environments. When used in a lab environment, the Optical Modem can be used in the validation process for free space optical communication space terminals .

The system is highly flexible and scalable. It can be configured with several optical transmitter (Tx) outputs with programmable skew and wavelengths, and a receiver (Rx) channel for very low optical input powers. The system can be configured to work with external optical transmitters and receivers.

Celestia STS offers the client the choice of fibre-in, fibre-out or copper-in, copper-out, or any combination of these. Every optical ground station is different and our Optical Modem adapts to the needs of the ground station and client.

A raw data ingest configuration can be supplied where the hard-decision data bits from the receiver is saved directly to disc. This extremely powerful tool allows clients to examine and/or process the raw, unprocessed data bits, using Celestia STS’ or the client’s custom processing. This transparent recording of data allows the client to use non-standard offline processing, without losing any of the data during a satellite pass.
