Abstract: A fiber optic adapter includes a mounting block having a first opening and a through opening extending into the mounting block from the first opening with a seat for receiving a body portion of a fiber optic connector and at least one flexible projection with a first end defining an aperture that is smaller than the first opening. The at least one flexible projection is configured to flex away from a rest position and away from a longitudinal axis of the through opening to allow the body portion of the fiber optic connector to reach the seat and configured to return toward the rest position when the fiber optic connector reaches the seat and to substantially prevent the removal of the fiber optic connector in a direction opposite its insertion direction when the at least one flexible projection is in the rest position.

Abstract: Fiber adapter modules for use as interfaces at both ends of multi-fiber trunk cables position the channels of plural fiber optic transceivers onto fibers of the trunk cables in an efficient manner, such that normally dark fibers of a trunk cables are utilized. The fiber adapter modules include trunk-side ports for receiving adapters of multi-fiber trunk cables and transceiver-side ports for receiving adapters carrying both transmit channels and receive channels of fiber optic transceivers. Optical interconnections are provided within the fiber adapter modules to place at least one transmit channel or at least one receive channel of a first fiber optic transceiver at a first trunk-side port and to place at least one transmit channel or at least one receive channel of a second fiber optic transceiver at the first trunk-side port.

Abstract: Push-pull fiber optic connectors and cable assemblies having a latch that is actuated by a cam surface are disclosed. The fiber optic connectors include a ferrule and a housing having the latch. A shroud fits over a portion of the housing and allows the craft to grab the shroud and push the shroud and hence the fiber optic connector into a suitable adapter or the like. Likewise, the craft can grab the shroud and pull on the same to remove the fiber optic connector out of the adapter or the like. The cam surface is disposed on a decoupling member, wherein the decoupling member is attached to the shroud so the components can move together. Methods of making the push-pull fiber optic connector are also disclosed.

Abstract: An optical fiber distribution enclosure includes a housing defining an interior, a first fiber distribution area disposed within an upper portion of the interior, a second fiber distribution area disposed within a lower portion of the interior and a signal splitting area disposed between the fiber distribution areas. A splitter module secured within the signal splitting area has a connectorized splitter input optical fiber and connectorized splitter output optical fibers. A fiber parking area is movably disposed within the lower portion adjacent the second fiber distribution area for temporarily storing splitter output optical fibers that are not routed to the fiber distribution areas. An input fiber distribution area disposed within the interior interconnects an optical fiber of a feeder cable with the splitter input optical fiber. The splitter output optical fibers are eventually routed to a fiber distribution area and interconnected with a corresponding optical fiber of a distribution cable.

The connector also includes first and second opposed splice members extending lengthwise from a first end proximate the end of the ferrule to an opposite second end, and the ends of the stub fibers extend between the opposed splice members at the first end thereof and are disposed in fiber-aligning grooves formed in the first splice member. The splice members are arranged with a fiber-receiving space therebetween to allow the optical fibers of the fiber optic ribbon to be inserted through the fiber-receiving space such that the optical fibers engage the grooves and are guided by the grooves into optically connected relation with the ends of the stub fibers.
