FCST FCST080701 Optical Fiber Identifier

$318.85

The FCST080701 is a handheld optical fiber identifier for non-intrusive traffic direction and tone detection on live networks. Using safe macro-bending, it displays core power and signal direction via LEDs without interrupting traffic. Featuring four interchangeable adapters, a sunshade, and a durable metal housing.

Non-Destructive Live Fiber Testing: Identifies traffic direction and relative core power without cutting the fiber or interrupting network services.
Tone Modulation Detection: Detects CW signals and 270 Hz, 1 kHz, and 2 kHz modulated tones with audible alert feedback.
Four Interchangeable Adapters: Includes head adapters for Ø0.25 mm bare fiber, as well as Ø0.9 mm, Ø2.0 mm, and Ø3.0 mm jacketed cables.
Integrated Sunshade Attachment: Shielding attachment minimizes ambient light interference during outdoor field testing.
Single-Key Operation: Streamlined single-button interface enables field technicians to perform fast, one-handed readings.
Metal Housing: Built with a durable metal casing to withstand daily field use.

Q: Will using this fiber identifier disrupt live active services?
A: No. The instrument uses micro-bending detection technology, allowing signal direction and core power measurements without cutting or interrupting active fiber links.
Q: What cable sizes are supported out of the box?
A: The standard package includes four swap-in adapter heads: Ø0.25 mm for bare fiber, plus Ø0.9 mm, Ø2.0 mm, and Ø3.0 mm adapters for standard pigtails and patch cords.
Q: Can this unit identify tone frequencies injected by an optical light source?
A: Yes, it recognizes 270 Hz, 1 kHz, and 2 kHz modulated signals and provides a continuous audible beep upon detection.
Q: How does the included sunshade assist during field work?
A: The sunshade clips over the adapter area to block intense ambient sunlight, ensuring consistent detection sensitivity during outdoor operations.
