Big Bear Solves Optical Impairment With EDC-Based Solutions
Big Bear Networks, delivering intelligence into the Optical/Electrical
interface for enterprise, metro and carrier networks, announced a solution to
the challenge of optical impairment in high-speed networks with its patented
electronic dispersion compensation (EDC) technology and it has successfully
delivered its products into multiple high-speed datacom and telecom markets.
During the last 24 months, Big Bear Networks has tightly integrated its
patented EDC technology, called Photronic Signal Processing (PSP), with
optical components to deliver the highest performance, cost-optimized modules
for high speed network applications. At 10 Gigabit and higher transmission
speeds, the bandwidth requirements in optical devices and limitations of the
fiber channel have made it difficult to develop economically feasible modules
that achieve system performance requirements.
Solving the OE interface issue with EDC and delivering the resulting
performance benefits requires the tight coupling of three very different
engineering disciplines; mixed-signal IC design, optical channel and component
expertise, and a system integration team to bring together the complete
solution. The absence of other EDC-based modules shipping in the market today
attests to the difficult engineering challenge of developing such high-speed
modules and sub-systems.
"Our talented engineering staff, which includes experts in mixed-signal IC
design, optical components, and system integration, has successfully developed
world class technology and products," said Mark Thompson, president and CEO of
Big Bear Networks. "We have completed the development of our PSP technology,
we've engineered it into market-leading products, and we've won significant
customer business, shipping products into three application segments."
Big Bear Networks is currently shipping for revenue into three markets, with
additional products planned for market introduction later this year. All of
the products are based on Big Bear Networks' PSP technology:
- Big Bear Networks announced 10GBASE-ZR XENPAK modules, targeted at
long-reach, single-mode (80-120 km) 10G Ethernet metro applications. This is
the first single-mode 10G transponder on the market to incorporate EDC.
- Big Bear Networks has successfully had its EDC-based ICs designed into 10G
Telecom line cards, which resolve optical impairment issues over single-mode
fiber transmission links.
- Big Bear Networks has also developed its 40/43G transponders, which have
been shipping for more than one year. The company supplies most of the early
adopter 40G transponder business, primarily with test equipment manufacturers
and Tier-1 system OEMs.
