Short for electronic dispersion compensation, EDC technology is supported by the Optical Internetworking Forum (OIF) – a group currently defining a 10 Gbps interoperability specification targeting optical links. The transmission distance of this specification supports up to 120 km (2400 ps/nm), however, the maximum distance currently supported is specified at up to 80 km. To achieve this reach extension and lower the cost of optics on existing fiber links, EDC technology, as offered in the new BCM8105 optical networking chip, provides customers a seamless upgrade on existing OC-48 trunks beyond 80 km to OC-192, while enabling the use of low-cost optics without the need to re-engineer the link.
