Big Bear Netwoks unveils Photonic Signal Processing technology to automatically correct fiber-optic impairments

May 20, 2002--Big Bear Networks today introduced its Photronic Signal Processing (PSP), a new technology that the company claims overcomes signal-degrading fiber impairments, enabling telecom carriers to deploy longer and faster fiber-optic links with minimum capital and operational expenditure.

Big Bear Networks today introduced its Photronic Signal Processing (PSP), a new technology that the company claims overcomes signal-degrading fiber impairments, enabling telecom carriers to deploy longer and faster fiber-optic links with minimum capital and operational expenditure.

Applicable to next-generation 10- and 40-Gbit/sec optical system products, PSP combines low-cost electronics and digital signal processing (DSP) to automatically correct for common fiber impairments--a task which previously required expensive components and equipment as well as time-intensive manual intervention by carriers, explain company representatives. By improving equipment vendors' system design margins, PSP has the potential to significantly reduce carriers' costs in both the metro/regional and multi-wavelength long-haul markets.

PSP is the foundation for a line of highly integrated electrical-optical interface solutions that Big Bear will bring to market starting later this year in the form of 10-Gbit subassemblies and transponders for long-haul applications; 40-Gbit transponders for cross-office, metro core/inter-office facility, and regional networks; and 40-Gbit subassemblies optimized for long-haul transmission. The products will be deployed in equipment such as DWDM transmission systems, IP/MPLS routers and switches, SONET/SDH cross-connects and add/drop multiplexers, and optical cross-connects.

Big Bear Networks, founded in June 2000 with an initial core team from Lucent Technologies, Nortel Networks, and Texas Instruments, is headquartered in Milpitas, CA. For more information, visit the company's Web site at www.bigbearnetworks.com.
