Prizm LightTurn Assemblies – Cables

prizm light turn

Computer Crafts has developed a number of PRIZM® LightTurn® assemblies in conjunction with our customers and have proven the products reliability and performance. Designed as a miniature detachable connector for high speed board mounted parallel optic modules, the PRIZM® LightTurn® connector provides passive alignment and novel retention features allowing multiple re-matings perpendicular to the printed circuit board. The PRIZM® LightTurn®connector consists of a multi-fiber ferrule with a photonic turn TIR lens array accepting cleaved fibers with an accompanying connector housing. The termination is simple and low cost requiring no polishing of fibers and easy testing, yet providing excellent coupling to high bandwidth mini-parallel optic modules.

The use of the PRIZM® LightTurn® connector in combination with US Conec’s MTP® brand MPO style connector provides a significant increase in card edge port density compared to using SFP transceivers, conventional array transceivers, or parallel active optical cables on the card edge. The connector is suitable for use across multiple applications including telecom, datacom, and the emerging high speed computercom markets and is available in a number of configurations.
