The ComNet 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 high reliability. 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. Plug-and-Play design ensures ease of installation, and no electrical or optical adjustments are ever required.

Key Features

  • 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
  • LED status indicators provide rapid indication of all critical operating parameters, including the location of fiber breaks or failed transceivers
  • Designed to meet full compliance with the environmental requirements
  • 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
  • Wide optical dynamic range - optical attenuators are never required
  • Hot-swappable rack modules
