General Instrument Corp., Hatboro, PA, and Fujitsu Network Communications Inc., Richardson, TX, will work together to market the latter`s N-Able Synchronous Optical Network technology to the North American cable-TV market. N-Able consists of a 2.5-Gbit/sec OC-48 add/drop transport system optimized for asymmetrical communications for broadcast video transport, plus duplex 44.736-Mbit/sec DS-3 modules for voice and data. The combination of N-Able with General Instrument`s video codec is expected to operate over hybrid fiber/coaxial-cable networks without affecting two-way communications.
