  • Description

    The TC8800 4-to-28 channel Telephone & Data Fiber Optic Multiplexer links or extends data & telephone lines in campus networks. In many instances the TC8800 can replace expensive channel banks.

    Users can mix or match telephone channels or RS-232, RS422 TTL, Dry Contact Closure, Dry Contact Detector and 2/4-wire 600 Ohm Analog Lines in increments of four channels. For example, a user could multiplex 20 telephone channels & 8 RS-232 data channels. It supports Telephone channels from 300Hz to 3.4Khz & asynchronous data rates to 19.2 Kbps.

    The TC8800 converts 2-wire FXS to fiber optics on the telephone side with ring down capability and FXO on the PBX side. Distances up to 80km are typical over single mode fiber, 4km over multimode fiber. Because it digitizes the analog signals (PCM), voice quality does not degrade over extended distances.
