描述 Description

The High-Speed Isochronous Multiplexer integrated circuit multiplexes up to eight Serial Telecom (ST-BUS) links onto a single 20 MHz loop to facilitate point-to-point data transport requirements. The MT90710 connects easily with standard Fiber Optic interfaces to form a complete electric to photonic conversion circuit. Optical transmission allows large bandwidth inter-shelf or, in distributed systems, inter-node communication by eliminating multiple data buses, cable inter-connect and attendant driver interfaces. The final result is a simple physical interface free of the radiated emissions and background noise susceptibility problems encountered in copper-wired environments.
