Abstract: A modular undersea optical fiber telecommunication system includes a plurality of fiber optic cable segments each containing fibers of a fiber type different from at least some of the other cable segments. Each cable segment has a plug unit at one end and a receptacle unit at the opposite end comprising mating halves of an underwater connector. The connector units contain a plurality of optical fiber contact terminals, and each optical fiber in the cable segment is terminated to a respective one of the contact terminals in the plug unit at one end and to a respective one of the contact terminals in the receptacle unit at the opposite end.

Abstract: A cable system for installation on the ocean floor or under another body of water includes a plurality of sub-sea junction boxes installed at spaced locations throughout a predetermined sub-oceanic cable network. At least some of the junction boxes are located at a predetermined distance off-shore from a respective on-shore cable junction node. A single main, high fiber count conduit extends from each off-shore junction box to the respective on-shore cable junction node. Each off-shore junction box has plurality of ports for releasable connection to a selected offshore cable terminated at the junction box, and a fiber routing unit in the junction box connects at least some of the ports to fibers in the main conduit.
