From Supernet--PMD will gettcha (beyond OC-192/10Gbps) www2.marketwatch.com YAFO Says PMD is Single Biggest Challenge Facing 40 Gbps Networks; Chairman Henry Yaffe Tells SuperNet Audience PMD is Potential `Show Stopper' TUESDAY, JANUARY 16, 2001 9:52:00 AM EST SANTA CLARA, Calif., Jan 16, 2001 (BUSINESS WIRE) -- SuperNet-- YAFO Networks Chairman and CTO Henry Yaffe told SuperNet attendees that polarization mode dispersion (PMD) is the single biggest challenge facing systems vendors and carriers as they attempt to deploy 40 Gbps optical networks. Speaking on a SuperNet panel that included representatives from Corning GLW, Zaffire and Coppercom, Yaffe said PMD is a problem not only for 40 Gbps networks, but also for carriers attempting to move from 2.4 Gbps to 10 Gbps. "PMD is a difficult, dynamic problem that up till now has made it impossible to implement reliable high-speed optical networks in many places," Yaffe said. "As carriers and systems vendors try to cross the chasm to 40 Gbps networks, PMD will be a show-stopper--without new, innovative solutions." Polarization mode dispersion occurs when different planes of light inside a fiber travel at slightly different speeds, making it impossible to transmit data reliably at high speeds. Massive growth in Internet traffic is driving more systems vendors and service providers to implement high-speed optical networks that move data at speeds of 10 Gbps, with 40 Gbps networks expected to arrive later this year and next year. The Yafo10 PMD compensator uses adaptive optical networking technology to alter the character of the bit-stream of light in real-time and overcome the PMD problem. "We believe the Yafo10 and Yafo40 represent crucial solutions for carriers and system vendors, and demonstrate the vision and world-class skills of our engineering team. "The Yafo10 will enable carriers to utilize thousands of miles of existing fiber, that is currently underutilized at speeds below 10 Gbps," Yaffe added.
