Polatis Trials Optical Switch

CAMBRIDGE, U.K. -- Polatis Ltd, the fibre optic switch developer, today announced first performance details of a 64 port all-optical switch demonstrator at the OFC2001, conference, Anaheim, California 19th,March.

Chief executive, Andrew Dames, stated " Our 64x64 all-optical switch card is the first demonstrator of a product range of scalable all-optical switches. What we find particularly exciting is that the intrinsically low insertion loss of these units will enable network service providers to roll out new levels of 'point & click' provisioning and protection for the next generation of intelligent optical mesh networks. This will assist the opening up of new market opportunities based on VPN's and bandwidth on demand. It's an extremely exciting time."

The Polatis switch offers ‘any-to-any’ optical connectivity between all input ports and all output ports. The proprietary 3D switch core that uniquely characterises the Polatis design is based on innovative direct beam switching technology. Switching times are in the millisecond regime, for circuit provisioning applications. This highly scalable approach enables high port count switches to be fabricated with very low, path independent insertion loss and cross talk. This is particularly beneficial for network service providers as any unnecessary signal loss is extremely costly.

re: Polatis Trials Optical Switch Hey,

Anyone at OFC check into this item? Any details? Size of unit? Loss? Control structure?

re: Polatis Trials Optical Switch photonman - thanks for the details. Any idea of what termination is on the end of their fiber bundles. Also, is the system exactly 64 ports or are there some spares floating about?

re: Polatis Trials Optical Switch Counted 128 fiber connectors in total , MU type, angled for fiber management

re: Polatis Trials Optical Switch Interesting. 2 bundles of 64 then. no spares.

What sort of electrical connectors? Are the mirror controls on the subsystem or from elsewhere? Or did Polatis say there will be a controller and SW onboard?

Thanks,
Manoflalambda

re: Polatis Trials Optical Switch To manoflalambda,

Not sure about electrical connectors. Regarding your question of mirror controls, Polatis would not comment in detail , but did state it is not MEMS, so is mirror control the right question to ask here?

I believe there is an on board controller.

re: Polatis Trials Optical Switch Does anyone know what the primary
switching technology is (liquid
crystal or MEMS or holographic
crystal or ....)?

re: Polatis Trials Optical Switch Polatis have stated publicly that they are not using MEMS technology

re: Polatis Trials Optical Switch Also, an article I ran across via opticalkeyhole.com (I think), mentioned hiring 2 ppl with Ink Jet experience. Have they beaten Agilent to the punch?
