Marking the end of its first major field trial, Optinel Systems says Adelphia Communications Corp. has wrapped the trial of its PLEXiS MFX transport system.
The trial tested the long-distance optical transport of live digital video signals over Adelphia's Northern Virginia ring. Optinel's Functional Optical Multiplexer enables all-optical sharing of traffic among several sites, according to Optinel.
The system is designed as an alternative to SONET-based systems. "Optinel's system yielded several improvements over traditional systems, including better picture quality and lower error count," said Abe Naghibi, Adelphia's regional corporate director of engineering.
Optinel debuted its optical transport system for the cable market at the SCTE Cable-Tec Expo 2002 in June.
The company's transport system is a scalable system that enables information to remain in its hybrid fiber/coax-compatible format, thus reducing the cost and improving the performance of existing networks, according to the company. The "bolt-on" solution seamlessly interfaces with existing cable plant equipment, according to Optinel.
