XKL's New DarkStar(TM) In-Line Fiber Amplifiers Move Data at the Speed of Light

Compact, Energy-efficient 1U Devices Deliver Excellent Latency for Businesses
with Time-Sensitive Data Needs

REDMOND, Wash., Oct. 29 /PRNewswire/ -- XKL, LLC, a leading-edge provider of
enterprise fiber optic networking equipment, announced today that it has
launched a new family of in-line fiber optic amplification products that can
achieve unprecedented latency speeds.

In a realistic test bed running 40 channels of 10Gb/s data, XKL achieved a
one-way latency of just 6.071 milliseconds (fiber plus equipment latency) over
1231 kilometers of fiber - roughly the distance between Chicago and New York
City. This test was done using the new XKL DRA line amplification units with
1231 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 100Gb/s," said Len Bosack, CEO of
XKL and co-founder 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 optics
infrastructure by maximizing data throughput to create fast and reliable fiber
optic networks for enterprise data transmission. These compact 1Usub systems,
located along the fiber, move data with lower latency and cost than previous
solutions. The low latency and cost savings delivered by XKL's DarkStar fiber
optics amplification units make for a high return on investment, particularly
for businesses that rely on high speed data transfer to capitalize on market
opportunities.

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