Based on indium phosphide compound semiconductor technology, signal-reshaping large-scale integrated-circuit (LSI) is designed to handle complex signal distortion caused by polarization mode dispersion with differential group delay of 22 psec. LSI enables upgrade to 40 Gbps-based wavelength division multiplexing (WDM) transmission systems using optical fiber networks already in use for 10 Gbps systems.
Tokyo, Japan, Mar. 03, 2006 - NEC Corporation today announced that it has succeeded in the development of a signal-reshaping large-scale integrated-circuit (LSI) that facilitates a 40 gigabit per second (Gbps) optical fiber transmission system. The new LSI significantly enhances the quality and length of 40 Gbps-based wavelength division multiplexing (WDM*) long-haul transmission as compared with conventional systems, due to its ability to compensate for signal distortion resulting from optical fiber impairments.
In its research, NEC has verified the capability of the LSI to compensate for signal distortion, proving that …
