We Want Fast Internet

Bifrost has developed a cost and energy efficient, flexible and scalable method for Optical Transceivers to increase the transmission distance and capacity of fiber based networks. Service Providers can expect to save millions of dollars of both Opex and Capex expenses. With Bifrost technology, it is possible to transmit optical signals over distances  4 x longer (from 10 to 40 km) than possible with current (PiN photodetector based) technology. At the same time, it is possible to configure 8 x more users (256 instead of 32) on the same fiber, thereby allowing for improved economics of operations and investments for the telco / internet providers. It has been shown to have a global potential, and is compatible with existing fiber technology installed in networks around the world.

The heart of the technology is a  channel selective receiver capable of picking out 10 times weaker light than standard receivers can do today. With this, for the first time, multiple channel fiber-based internet to the home is possible with complete flexibility for the internet provider and without the use of costly optical filters. Bifrost can do this with low-cost standard lasers, and is fully compatible with deployed fiber. It presents the following advantages of transceivers for the Fiber-Internet (access) market

  • Light detection at least 10 x better than that from competitors
  • Simplified electronics
  • Tunable without optical filters (channel selection just like FM radio)
  • Based on standard high volume components to keep costs low
  • Platform technology also applicable to any competitor’s solution
  • Disruptive and patented design

4 x Distance – 8 x number of users - 10 x less Central Offices

With Bifrost Transceiver for the Fiber-Internet Access Market

$50 Billion in lost revenue for operators

Internet service providers today agree that fiber-based Internet to the home or to the mobile mast is the only solution that can deliver sufficient bandwidth.

Unfortunately, service providers struggle to make profit on their operations due to the inefficient way fiber is used today.

The Central Office needs to be within 10 km of the end user or mast for mobile backhaul purposes, and only one optical channel can be put on each fiber.

The result is that service providers need too many fiber cables and too many central offices that use too much energy, while failing to generate sufficient revenue to be really profitable.

Fewer central offices – More business

Our solution increase the distance to the central office  by a factor 4, and allows for 8 times more end users on the same fiber, thereby enabling the Internet Providers to decommission 90% of the central offices, thus making their business case much more attractive.

Superior performance – standard components – low cost – patented*

The product is developed by the Danish company Bifrost Communications ApsIt is an  optical transceiver module consisting of a combination of Bifrost proprietary technology and standard components; all integrated in a standard form-factor module. This secures interoperability with existing infrastructure.

The optical front-end and the high-speed integrated circui (IC) chipsets for signal processing are developed by Bifrost Communications. The optical front end includes transmitter output and receiver input. They are constructed by standard components, but put together in a new way e.g. by the inclusion of a local oscillator (LO) laser in the receiver. The proprietry IC performs high-speed signal processing.

All data switching and traffic processing is handled by standard chipsets that are available on the market today. By combining proprietary innovations with standard tech in a standard form factor, we ensure full interoperability with legacy equipment, thereby enabling the Internet Providers to gracefully migrate to the Bifrost technology platform.
