Researchers at UCL, London, say that a new optical communications module they have developed could make slow internet speeds and the commonly-experienced drop in speed at peak times a thing of the past.

Consistent high-speed broadband connectivity is the UCL claim for its new receiver technology that enables dedicated data transmission rates of more than 10,000 megabits-per-second (equivalent to 1.25 gigabytes) for a super-fast but low-cost broadband connection,potentially to every home.

The new receiver retains many of the advantages of coherent receivers, but is simpler, cheaper, and smaller, requiring just a quarter of the detectors used in conventional devices. The simplification was achieved by adopting a coding technique to fiber access networks that was originally designed to prevent signal fading in wireless communications. This approach has the additional cost-saving benefit of using the same optical fiber for both upstream and downstream data.
