May 1999TC Communications Inc.Request Info
TC Communications Inc. has unveiled its TC8000X, a 4- to 24-channel analog/intercom fiber optic multiplexer that supports voice bandwidths from 300 to 3400 Hz. It provides intercom and analog interfaces in four-channel increments; the intercom interface is for four-wire voice communication, and the analog is 600-(omega) transformer-coupled. The multiplexer digitizes the analog and voice signals so that voice quality does not degrade. Distances to 30 km are typical over single-mode fiber and 4 km over multimode fiber.
