    Abstract: A method for preparing a ferrule assembly avoids polishing while providing adequate control over fiber end protrusion and co-planarity. A distal end of the fiber is prepared before securing the fiber in a ferrule, and before or after inserting the fiber into the ferrule. The prepared fiber is manipulated to provide a desired spatial relationship between the fiber end and the ferrule's end face, and then secured to maintain the desired spatial relationship. Preferably, the fiber end is prepared using a laser cleaving technique to provide a suitable end without abrasive polishing. An interferometer may be used to obtain measurements, during manipulation of the prepared fiber within the ferrule, that indicate whether the prepared fiber is satisfactorily positioned. In accordance with other aspects of the invention, a ferrule assembly prepared in accordance with the method, and a connector or other optical package including such a ferrule assembly are provided.

  • Patent number: 8917966
    Abstract: An enclosure system for receiving a cable includes an enclosure having an inner chamber and an open position exposing the inner chamber and a closed position covering the inner chamber. A cable receiving port in a wall of the enclosure extends along a longitudinal axis from outside of the enclosure into the inner chamber. The cable receiving port is configured to receive a cable therein when the cable is advanced axially into the port without rotation of the cable when the enclosure is in the closed position. A mating member is associated with the cable receiving port that limits rotation of the cable when the cable is advanced axially into the port. An axial retention member is associated with the cable receiving port that limits axial movement of the cable out of the port when the cable is advanced axially into the port to a lock position.

  • Patent number: 8894298
    Abstract: A fiber optic connector has a connector outer housing and a connector inner housing. The connector inner housing has a projection to interact with a latch on an adapter into which the connector is inserted. The force required to move the connector outer housing relative to the connector inner housing is less than the force to remove the connector inner housing from the latch. A groove or opening may also be formed in the connector outer housing to effectively shorten the connector outer housing and prevent interaction of the latch with the outer housing, reducing debris.

  • Patent number: 8894296
    Abstract: The invention provides a plug (100) which is adapted to be connected to a cable, such as an Ethernet cable, the plug (100) having a generally rectangular cross section and being dimensioned and arranged to be received by an aperture in a socket. On opposite lateral faces of the plug a region, or layer, of conductive material (24, 26) is provided for the transmission of electrical current to/from the cable. Use of the invention therefore permits cabling that has conventionally been used to supply data to also supply power, typically in excess of 200 Watts or so. Such amounts of power are sufficient for operating most equipment that also requires a data connection.
