COMNET FDC2 Overview

The FDC2 Dual-Channel Fiber Optic Cable Breakage Monitor / Detector from ComNet is designed to detect and report a breakage or the loss of optical signal in multimode fiber plants. Featuring a self-contained transmitter and receiver, it provides 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. This dual-channel unit features two independent transmitter and receiver units in one compact package, and is suitable 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
-40 to 167°F ambient operating temperature range 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
Can be used standalone or mounted in a rack - thanks to ComFit
May be DIN-rail mounted via the DINBKT1 or DINBKT4 DIN-Rail Adapter Plates (sold separately)
Applications include 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
