Vitesse and CyOptics demonstrate interoperability

Oct. 11, 2001--CyOptics Inc., a developer of Indium Phosphide based active optical components, and Vitesse Semiconductor Corporation announced interoperability of their 10Gbps optical and electronic components.

CyOptics Inc., a developer of Indium Phosphide based active optical components, and Vitesse Semiconductor Corporation (NASDAQ: VTSS) announced interoperability of their 10Gbps optical and electronic components. The companies demonstrated optical transmission using the Vitesse VSC7991 10Gbps modulator driver and the CyOptics 10Gbps Electro-Absorption Modulator (EAM) at the European Conference on Optical Communications (ECOC) in Amsterdam.

The CyOptics 10Gbps EAM is a highly compact, low-cost optical modulator, targeted to replace the traditional Lithium Niobate modulators in metro and long reach applications. Fabricated using mature semiconductor processing technology, its Indium Phosphide (InP) based design provides excellent manufacturability, a crucial advantage in an industry striving to lower cost while improving performance. Pricing of the 10Gbps EAM is $1,500 in quantities of 1,000.

The Vitesse VSC7991 is a single chip 10Gbps EAM driver with bandwidth sufficient to accommodate Forward Error Correction (FEC). Its 3Vp-p drive voltage enables excellent EAM eye characteristics. It also performs seamlessly with Vitesse's extensive line of 10Gbps SONET/SDH multiplexer ICs. For design flexibility, the VSC7991 is available in die form, with known good die tested at speed, or a low-cost 32-pin 5mm CQFXP package. In die form, the VSC7991 is priced at $126 in quantities of 1,000. In the CQFXP package, the VSC7991 is priced at $151. Both are in full production now.
