A clip-on coupler is available for bare fibre access where terminated ends are not available.
The FTS 20C allows bi-directional communication from a centre point on the fibre link or from an unterminated end. When used with a fibre talk set – such as the FTS2 – a user can access the intended talk fibre at a mid-point across the span, usually at the splice enclosure.
The FTS-20C can also be used in conjunction with a Laser Source and Tone Detector to inject or detect 2 kHz test tones. It works at 1310, 1550, or 1625 nm. Coupling efficiency is approximately 18 dB.
