DP Seals has developed special high-performance seals and boots for a
range of sub-sea optical fibre/hybrid cable connectors manufactured by
Seacon Europe (www.seaconeurope.com). This novel cable gland arrangement
has been developed to provide both anchorage and sealing for each layer
within the cable construction, including outer sheath, steel tube and
individual optical fibres. The seals and boots are made from a specially
formulated hydrogenated nitrile material, chosen for its high tensile
strength, salt water tolerance and effectiveness at high pressure and low
temperature. Two nitrile sealing glands seal the outer sheath and steel
tube, locked into place with tapered sleeves to ensure that controlled
compression is maintained at all times. additional boots provide
secondary sealing to the individual optical fibres and prevent the
ingress of pressure compensating fluid from the connector into the steel
tube.
