T-FI350
SKYCOM
The SKYCOM T-FI350 Optical Fiber Identifier is designed to identify the direction of transmitted optical fiber and display relative core power without damaging the bent fiber. When traffic is present, the instrument activates an intermittent audible tone so technicians can recognize an active line during maintenance.
In addition to traffic direction, the T-FI350 recognizes modulation signals at 270Hz, 1kHz and 2kHz. When a modulation frequency is detected, a continuous audible tone is activated. This combination of direction indication, power display and frequency recognition allows one instrument to support several common live-fiber identification tasks.
Four replaceable adapter heads are supplied for Ø0.25, Ø0.9, Ø2.0 and Ø3.0 fiber or cable. The metal housing is designed for repeated field use, while the sunshade improves visibility during measurement. Power is supplied by a 9V alkaline battery.
Easy-to-use “ONE KEY” operation.
Identifies traffic direction and 270Hz, 1kHz and 2kHz frequency tones with audible warning.
Displays relative core power during live-fiber identification.
Sunshade supports more accurate field testing under bright conditions.
Easy-to-replace adapter heads for multiple fiber and cable diameters.
Durable metal housing and quality construction.
Low-power indication for battery status.
