Product Description

The Fathom Tether is a high quality tether cable designed specifically for ROVs and other subsea applications. It is neutrally buoyant, has 350 lb breaking strength, and is embedded with water-blocking fibers to seal any leaks. With diameters of 4mm and 7.6mm, these tethers are slimmer than the vast majority of comparable ROV tethers.

The tether carries one or four unshielded twisted pairs (UTP) of 26AWG wire. These pairs are colored and arranged in the same fashion as a Cat5 networking cable including cross-talk resistance.

The core of the cable contains Kevlar strands for strength and Dacron fibers for space filling. Both fibers are impregnated with waterblocking compound to block any leaks caused by nicks or rips in the cable. The high-visibility yellow polyurethane foam jacket resists abrasion and provides neutral buoyancy.

The stiffness of the cable is designed to be flexible enough to give plenty of freedom to your ROV, but stiff enough that it does not become tangled easily.

The capabilities of this tether are meant to provide design flexibility and a wide variety of uses.
