Optical Transceiver Extend Gigabit Links To 100 km

The GBE1250ELX extended, long-haul optical transceiver enables Gigabit Ethernet and Fibre Channel networks to reach lengths of 100 km and puts them in the metropolitan-area network class. Conforming to the Gigabit Interface Converter (GBIC) specification Rev. 5.3, the hot-swappable module is designed to immediately reduce the costs of maintaining remote connectivity through traditional telecommunication service options.The transceiver reliably transmits data across optical networks at gigabit speeds over "dark fiber," thereby eliminating the need for costly T-carrier lines from local exchange carriers. A distributed feedback laser and its decreased chromatic dispersion characteristics are the key to the module's long-haul performance. The electrical-to-optical serial transceivers operate at 1062.5 and 1250 Mbaud rates.
