Yamasaki TF916 optical fibre identifier

Friday, 14 January, 2011


Testing for traffic is essential when installing or maintaining optical fibre networks to avoid disrupting live communication. The Yamasaki TF916 clamps onto the outside of the fibre so users don’t have to disconnect the optical fibre to test for signals in the core of the fibre.

The clamp can be used to test from bare fibre through to thicker jacketed fibre cable of 3 mm. The optical fibre identifier can identify the traffic direction, frequency and optical power used over the fibre.

Fibre-optic sensors are clamped onto the outside of the optical fibre through a low insertion loss macrobending technique. Without overstressing or damaging the fibre, the optical fibre identifier allows the sensitive InGaAs photodetectors to clamp onto the fibre.

The direction of the traffic is indicated and displayed by the device when traffic is detected.

The device is equipped with audible tone indicators as well as visual displays to ensure that the product is capable of being used as a diagnostic tool in addition to a verification and troubleshooting tool for fibre-optic installations.

Suitable applications include: fibre identification; relative optical power comparison; tone detection (CW, 270 Hz, 1 and 2 KHz); high-loss point identification; splice and connector verification; optical signal comparisons; historical relative power comparisons.
