Fibre optic tethers can be used to remotely control different types of vehicles, bringing back video signal or other sensor information as well as transmitting commands.

This disposable spool offers in a very compact and lightweight package a precision wound, untwisted optical fibre for long distance pay out avoiding heavy, bulky and expensive cable tethers.

The deployable side of the spool which is connected to the control equipment is equipped with a connector directly mounted onto the extruded overcoated fibre. The distal fibre end which is connected to the vehicle with a hermetic feed-through is pigtailed with a 1.8mm standard jacket.

The fibre spool is disposable. It is not possible to reuse the fibre after deployment.
