XKL's DarkStar in-line fiber amplifiers achieve 6-s latency

OCTOBER 30, 2009 -- In a realistic test bed running 40 channels of 10-Gbps data, XKL achieved a one-way latency of 6.071 milliseconds (fiber plus equipment latency) over 1,231 km of fiber.

OCTOBER 30, 2009 -- XKL LLC, a provider of enterprise fiber-optic networking equipment, has launched a new family of in-line fiber-optic amplification products that it claims can achieve "unprecedented" latency speeds.

In a realistic test bed running 40 channels of 10-Gbps data, XKL achieved a one-way latency of 6.071 milliseconds (fiber plus equipment latency) over 1,231 km of fiber -- roughly the distance between Chicago and New York City. This test was done using the new XKL DRA line amplification units with 1,231 km of actual fiber.

"This milestone underscores my firm belief that our designs provide superior optical physics with an eye towards complex modulation formats of the future. Transmission development will not stop at 100 Gbps," claims Len Bosack, chief executive officer of XKL and cofounder of Cisco Systems. "By leveraging the inherent, but often untapped, physics of fiber-optic components, we can increase speeds with devices that use less power, less space, and require less cooling."

The new DRA and DBA line amplification units optimize existing fiber-optic infrastructure by maximizing data throughput to create fast and reliable fiber-optic networks for enterprise data transmission. The compact, 1-U subsystems, located along the fiber, reportedly move data with lower latency and cost than previous equipment.

XKL's DRA and DBA units are available and shipping now.
