Marine fiber optic spools
The RBOB fiber optic spools are ideal to remotely control underwater tethered vehicles that have to operate in conditions where it is dangerous or impossible to have an onboard human presence, and where radio frequency signals cannot be transmitted.
These disposable* systems are built in very compact and lightweight packages where the optical fiber is reinforced by a custom design cable and spooled with a high precision, offering a high speed and detwisted deployment of the optical fiber over long distances.
The deployable side of the spool is equipped with an ST connector to the control station on a support vessel or on land, while the opposite fiber end is pigtailed with a 1.8 mm standard jacket to be directly connected to the underwater robot with a hermetically sealed interface.
These spools, also called “tapes”, can be made with either singlemode or multimode optical fibers.
Please contact us to discuss your specific requirements.
*there is no possibility to re-use the fiber after deployment; the fiber is dumped into the sea.
