Irvine, CA----- A new Ethernet, Phone & Data multiplexer from TC Communications optimizes fiber optic cable usage by multiplexing one 10/100M Ethernet, four Telephone and, optionally, four channels of data over single mode or multimode fiber. A “one fiber,” two-way communication option doubles existing fiber usage. Rate control is optional on the Ethernet Port for Data Service Providers. The TC8520 converts 2-wire FXS to fiber optics on the telephone side with ring down capability and FXO on the PBX side. Because the TC8520 digitizes the analog signals (PCM), voice quality does not degrade over extended distances. 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 offers rate control in increments of 32Kbps. It is IEEE 802.3/802.3u/802.3x compliant. Setup, diagnostics and control is accessed via Serial Terminals, Telnet or SNMP management ports. It supports distances to more than 100 km and offers Redundant power and optics, including automatic switchover features for maximum reliability. It is available “Industrial Hardened” (-40o to 80o) for extreme environments.Typical applications include multiplexing Ethernet, Telephone & Data circuits to maximize use of existing fiber optic networks.Specializing in Process Control, SCADA, Manufacturing & Traffic Control communications networks, TC Communications, Inc. designs, manufactures and sells a wide variety of specialty and general purpose Fiber Optic Connectivity Devices---including all types of Ethernet Switches, Ethernet Media Converters, Modems, Multiplexers, Telephone/Data Multiplexers and Telephone Extenders.
