Model TC2400 High Speed Self-Healing (Ring) Multi-Drop Fiber Optic Modem TC2400S  Stand Alone/Wall Mount unit Features Product or Application Questions (click here) Async Data Rates up to 1 Mbps Sophisticated Tx Rx Upstream, Downstream Fault Detection Multimode & Single Mode (850/1300/1550nm) Distances up to 100km Single or Dual RS-232, RS-422, RS-485 Ports  Anti-Streaming (Anti-Jabber) Built-In Power Redundancy Local Dry Contact Alarm Relay Rackmount or Standalone Extend telephone lines with TC1900 RS-232/Fiber Phone Extenders Description Intended for self-healing ring topologies, the TC2400 High Speed Multi-Drop Fiber Optic Modem links monitoring devices (RTUs or PLCs) fitted with RS-232, RS-422 or RS-485 interfaces to a Host controller or CPU. The Self-Healing Ring scheme is sophisticated, i.e. it detects upstream and downstream failures on both Tx and Rx, and automatically re-routes any cable or equipment failure to insure uninterrupted operation. Asynchronous data rates can be up to 1 Mbps*.  The RS-485 electrical port can be multi-dropped. A special version, Model TC2400T, is available for extreme temperature (-20°C to 70°C) applications. Each unit comes standard with two pair of fiber interfaces and either one RS-232, RS-422 or RS-485 interface.  Units with a second RS-232, RS-422, and RS-485 interfaces are optional.  "Anti-Streaming" capability is standard.  Anti-streaming prevents a single node failure (e.g. "babbling") from bringing down the entire network. Diagnostic LEDs are provided for "Tx", "Rx", "Fault", and "Power" and more.  Diagnostic functions include local & remote loopback and a built-in signal generator. The TC2400 is compatible with all popular types and sizes of fiber optic cable and is available multimode (850/1300nm) or single mode (1300/1550nm).  Fiber optic connectors are ST or FC.  Electrical connectors are RJ-11 female.  Power is 12VDC; optional 24VDC, -48VDC, or 115/230VAC with an external power cube. A Self-Healing ring consists of two data paths, Ring A and Ring B, with each data path running in an opposite direction to the other.  Under normal operation only the primary data path (Ring A) is used.  When there is fault (cable or failed device), the data path will turn around before it reaches the fault or failed unit and use the secondary data path to complete the link.  In this manner, the data path will remain intact. *Data rates vary according to interface.  See specifications.
