Objectives
The project was aimed at developing improved optical components for use in DBS distribution systems based on optical fibre technology.
Challenges
The project has addressed the issues associated with the use of semiconductor lasers and detectors in the analogue optical transmission of DVB-S signals over a fibre distribution network. In particular the issues associated with the impedance match of these components, and the associated gain ripple, whilst maintaining good electro-optic and RF performance has been addressed.

Current Status
The project has been successfully completed. New lasers and detectors are now available, and these have been designed into the next generation of optical LNB and receivers. Trial manufacturing runs of these new products are underway, and full scales production will be initiated following their successful completion.
