Comnet FDC2M Two Channel Fiber Optic Cable Break Monitor

Two Channel Fiber Optic Cable Break Monitor, mm, 2 fiber.

The ComNet FDC1 single-channel modems are designed to detect and report a breakage or the loss of optical signal in multimode 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.

• Instantaneously reports optical fiber breakage or damage locally or remotely
• Dry relay contacts may be configured for NO or NC operation
• Automatic resettable solid state current limiters for modem protection
• Voltage transient protection on all power and signal input/ output lines provides protection from power surges and other voltage transient events
• Ambient operating temperature range: -40 degree C to +75 degree C for deployment in virtually any unconditioned out-of-plant or roadside environment
• Bi-color status indicating LEDs provide rapid indication of critical operating parameters
• Plug-and-play design for ease of operation – no optical or electrical adjustments required
• Hot-swappable rack modules
• Interchangeable between stand-alone or rack mount use – ComFit
