Big Bear Raises $18 M for 10/40 Gbps Photonic Signal Processing

Big Bear Networks, a start-up based in Sunnyvale, California raised $18 million in a third round of private venture funding for its next-generation 10 and 40 Gbps optical system products. Big Bear said its electronic dispersion compensation technology automatically corrects for the fiber impairments (e.g., modal dispersion, chromatic dispersion, polarization mode dispersion) that become more severe as systems move toward greater speeds and transmission distances. Its Photonic Signal Processor (PSP) could be used in electrical-optical interfaces in equipment such as Ethernet switches, DWDM transmission systems, IP/MPLS routers and SONET/SDH cross-connects. The new funding was led by Menlo Ventures. Other participants include previous investors Accel Partners, Austin Ventures, Oak Investment Partners, and Sequoia Capital.
