Vitesse Launches Transponders with Small Form Factor, Low Power, Price

6/11/2003 - Vitesse Semiconductor Corp. (Nasdaq:VTSS) announced the availability of its small form factor (SFF) 10 Gbps, 300-pin MSA compatible transponders for short, intermediate and long reach applications: the VIT5020, VIT5040 and VIT5080, respectively.

These SFF (2.2 x 3 x 0.53 inches) transponders achieve dramatic power and size reduction by incorporating Vitesse developed, highly integrated, CMOS ICs within each module. The principal device is the VSC8473 CMOS transceiver, which combines both Mux and Demux functions into a single IC. It allows the transponders to attain an all-time industry low of four watts (4W) of power under typical conditions for both IR and LR applications and assists in meeting the size requirements of the SFF specification. The advanced features of the transceiver also enable diagnostic and line loopback capabilities along with excellent jitter and dispersion performance. Another Vitesse component in the device is the VSC7983 10 G EML laser driver.

By replacing many of the high-priced, size prohibitive optics with advanced electronic components, Vitesse gains a competitive advantage in delivering transponders to Metro equipment providers. The small size, low cost and lowest power allows OEMs to deliver a higher density of 10 Gbps transponders on line cards; three key requirements needed for the migration to 10 G technology.

"By integrating advanced, high-performance CMOS ICs into the VIT5020, VIT5040 and VIT5080, Vitesse achieved the lowest power consumption currently available in the industry, met smaller size specifications and reduced the cost of 300-pin MSA compliant SFF transponders without sacrificing performance," stated Amit Jain, vice president of the Optical Systems Group, from Vitesse's Transport Product Division. "With this product introduction, the industry has hit a turning point where smarter electronics will marginalize the importance and cost of optics in transport links."

SFF 10 Gbps Transponders

In addition to the new functionality, the SFF transponders include all of the industry-recognized features of Vitesse's 10 Gbps transponder product family: an I2C interface for configuration, monitoring and alarms; an optional jitter filter; and compliance with Telcordia GR-253, ITU-T G.691 and IEEE 802.3ae specifications. Vitesse ensures standards compliance in its family of 10Gbps transponders by incorporating the requirements sanctioned by the 300-pin MSA and Serial Optical Internetworking Forum (OIF-SFI4-01.0) specification.

The VIT5020, VIT5040 and VIT5080 are sampling now with production scheduled for the third quarter of 2003. Pricing varies by distance with the VIT5020 below $1500 and the VIT5080 below $3500 in volume pricing.
