The ComNet FDC1 single-channel and FDC2 dual-channel modems are designed to detect and report a breakage or the loss of optical signal in either multimode or single- mode fiber plants. Featuring a self-contained transmitter and receiver, these units provide an optical output that is transmitted continuously through a customer-furnished fiber loop, where it returns to the internal receiver section. Should the optical path be lost through a deliberate or unintentional breakage of the fiber, relay contacts in the modem immediately change their state and report the loss of optical signal. These contacts are user-configurable as either normally open (NO) or normally closed (NC), and may be utilized for either a local or remote indication of cable plant tampering, damage, or failure. The dual-channel version contains two independent transmitter and receiver units in one compact package, and is ideal for continuously monitoring the optical status of two separate fiber loops.

Features

  • One or two fiber loop units available
  • Instantaneously reports optical fiber breakage or damage locally or remotely
  • Dry relay contacts may be configured for NO or NC operation
  • Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.
  • Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events.
  • Standard ComFit models are hot-swappable.

Applications

  • Fencing and Perimeter Surveillance: Optical fiber woven into fencing or other structures
  • Solar Panel/Photovoltaic Array (PVA) Theft Protection
  • Protection of High-Value Assets and Facilities
  • Continuous Status/Continuity Monitoring of Mission-Critical Fiber Optic Trunk Cables
