Abstract: A module and harness are described that allow for connectors in each to be mated with other connectors in a key up to key down orientation. The module and harness may also be a part of a larger optical assembly. The optical fibers in the module and harness connect a multi-fiber ferrule on one end with a plurality of connectors on the other end, at least some of adjacent optical fibers extending from the multi-fiber ferrule are not connected with adjacent connectors at the other end.

Abstract: A pinning system for use with prefabricated barriers and a method of assembling prefabricated barriers is disclosed. The pinning system permits custom-sized, prefabricated barriers to be arranged between adjacent barrier sections so that a continuous barrier can be obtained. The pinning system includes slideable elongate pins which are adapted to be selectively moved between a non-extended position at which elongate pins are located at least substantially within a passageway, and an extended position at which a portion of the elongate pins protrudes outside of the passageway beyond the exterior surface of the barrier section from which it is initially arranged.
