Instant Mobile Diagnostic for Combined Audio and Video Lines

The Canare FCT Hybrid Fiber-Optic Cable Checker Kit is a professional diagnostic system that acts as an essential tool for maintaining an all-in-one audio cable and video cable combined infrastructure. In fast-paced live television production, tracking down a signal fault across long umbilical lines can take hours. This compact, battery-powered testing kit replaces racks of heavy bench-top scopes, letting engineering crews verify the integrity of camera-to-CCU lines right on the stadium floor or inside outside broadcast (OB) van staging areas.

Unified Optical and Copper Verification

Because SMPTE 304 and Japanese OC systems rely on a hybrid architecture to function, a single cable defect can disrupt your entire broadcast pipeline. The FCT tester checks both media paths simultaneously. Its 1310nm laser engine pinpoints optical power levels and decibel (dB) signal loss across delicate single-mode glass lines (carrying uncompressed 4K/8K video). At the same time, its electrical testing blocks map the internal copper conductors, immediately flagging short circuits or broken pins affecting intercom audio networks, microphone lines, and CCU power lines.

Field-Hardened Operational Protocol

Weighing under 600 grams combined, this two-piece diagnostic kit is built for smooth, one-man field operations. Technicians simply hook the compact loop-back unit to one end of the cable run and attach the main testing unit to the opposite end to get an instant system analysis. To ensure accurate readings and protect the sensitive testing diodes from damage, engineers should always touch the cable's outer metal shell to a ground source to discharge static electricity before connecting the loop-back hardware first.
