ABSTRACT:
A fiber optic cable connection for high pressure environments utilizes a er optic cable having (i) a multiplicity of fiber optic strands extending axially therein, (ii) a strength member extending axially in spaced relationship thereabout, (iii) an outer jacket, and (iv) a filler matrix within the strength member and in which the strands are encased, a precision connector with an inner face having an axially extending recess and with axially extending passages extending from the transverse wall of the recess to the outer face of the connector member and through which the fiber optic strands extend. A preload insert member is disposed about the strands with its outer end extending into the recess of the connector and a peripheral shoulder abutting the inner face of the connector member. The strength member of the cable is disposed about extending the reduced diameter portion of the insert member. A body member is disposed about the insert member and has its outer end extending over the inner end portion of the connector. A nut threadably engaged on the inner end portion of the insert member and abutting the inner end of the body member is tightened on the insert member against the body member to tension the insert member above a predetermined value. A relatively rigid resin filler is provided in the insert member about the strands connector member, and a relatively compressible filler in the inner end of the insert member, and a sealing boot extending about the cable jacket over the strength member and nut and onto the body member.
