Comnet FDX72M1 Universal Data Drop & Repeat Data Transceiver

Universal Data Drop & Repeat, 1 Fiber, MM. The ComNet FDX72M1 Drop-Insert-Repeat Transceiver unit is a fully-digital modem designed for implementing RS232, RS422 or RS485 2 or 4-wire data communications networks of the highest possible reliability. A network of FDX72 units can support one full-duplex or two half-duplex data channels. These transceivers also feature data translation to convert between data protocols. Data re-clocking and regeneration permit an almost unlimited number of transceiver/controller units to be used within the network. These environmentally hardened transceivers are ideal for use in unconditioned out-of-plant or roadside installations and, unlike many competing designs, only one optical fiber is required between units. Combine these units with the ComNet FDX72M1 product as an end link to create a linear Drop-Insert-Repeat chain. Plug-and-play design ensures ease of installation, and no electrical or optical adjustments are ever required.

• Meets EIA RS232 and RS422/RS485 (2 or 4-wire) specifications (Simplex or Duplex Operation)
• Two Data Channel Capability: One full duplex or two half-duplex channels
• Only one optical fiber required between units
• Full data re-clocking and regeneration: no limit to the number of transceiver units used within the network
• Supports supervised multiple master architecture for unparalleled network reliability
• Remote Fault Indication allows the user to determine when a fiber break or loss of prime operating power has occurred, or a transceiver in the field has failed
• LED status indicators provide rapid indication of all critical operating parameters, including the location of fiber breaks or failed transceivers
• May be used to provide serial data protocol conversion between nodes (consult factory)
• Designed to meet full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment
• Robust design assures extremely high reliability in unconditioned out-of-plant/roadside environments
• NTCIP compatible
• Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events
• Wide optical dynamic range: optical attenuators are never required
• Hot-swappable rack modules
• Interchangeable between stand-alone or rack mount – ComFit package
• Units may be DIN-Rail mounted by the addition of ComNet model DINBKT1 or DINBKT4 adaptor plate
