New Self-Healing Fiber Multiplexer Features Benefits of “Channel Mapping”

TC2850 Standalone/Wallmount Unit

IRVINE, CA-----A new Fiber Optic Self-Healing Ring Multiplexer from TC Communications features the potential benefits of Channel Mapping:

Two independent communications networks (e.g. SCADA networks) in one self-healing ring topology
Cost savings through flexible channel configurations
Faster polling rates.

Intended for SCADA, Traffic Control, Process Control, Power & Gas & Security networks, Channel Mapping enables users to configure specific channels from the Master to designated Slave units on a fiber ring. Designated channels could include both a dedicated virtual point-to-point channel and a broadcast poll-response channel on each Slave.

The Model TC2850 12-Channel Multi-Drop Multiplexer offers a sophisticated Self-Healing Ring scheme and is available with dual masters for maximum reliability. Fault conditions are detected both Tx and Rx, upstream and downstream of each unit, and automatically re-routed to maintain Ring integrity. Dry contact alarms can be connected to RTUs/PLCs to help pinpoint the location of a fault.

It is transparent to all protocols, supports data rates up to 120 Kbps and is compatible with RS-232, RS-422 or RS-485 (2- or 4-wire) interfaces over single mode or multimode fiber. Options include Hardened Temperature versions (-20°C to 70°C & -40°C to 80°C) for extreme environments and Conformal Coating to prevent corrosion, etc.
