TC8520
Telephone, Data & 10/100 Ethernet Multiplexer (1-9 Ch.)

The TC8520 Ethernet, Phone & Data multiplexer optimizes fiber optic cable usage by multiplexing one 10/100M Ethernet, 4 Telephone and, optionally, 4 channels of serial data over single mode or multimode fiber. A “bi-directional 1-fiber” option doubles existing fiber optic cable usage.

It converts 2-wire FXS to fiber optics on the telephone side with ring down capability and FXO on the PBX side. Serial data interface options are RS-232, RS-422, TTL and Dry Contact. It also supports 2/4-wire analog (600ohm).

The Ethernet port auto-negotiates at 10/100M with full 10Mbps throughput and enables rate control in increments of 32Kbps. It supports distances to more than 100 km and offers redundant power/optics, including automatic switchover, for maximum reliability. It is available “Industrial Hardened” (-40C to 80C) for harsh environments.
