  • Patent number: 8652287
    Abstract: An apparatus for positioning an optical device includes (i) a holder assembly for holding an optical device and for limiting movement of the optical device within the holder assembly to movement in the Z-direction and (ii) a housing for permitting limited movement of the holder assembly in the X-direction, for supporting and optionally permitting movement of the holder assembly in the Y-direction, for supporting and for substantially preventing movement of the holder assembly in the Z-direction. When the holder assembly optionally holding the optical device is positioned within the housing to obtain a desired position of the optical device, a bonding material may be used for fixing the location in the X-direction, and optionally the Y-direction, of the holder assembly within the housing. A method of operating the apparatus for obtaining a desired position of an optical device is further provided.

  • Publication number: 20140029909
    Abstract: A fiber optic harness assembly includes first through sixth groups of optical fibers and first and second connector sets. The groups of optical fibers are arranged in data transmission pairs such that one group of each pair is configured to transmit data and the other group is configured to receive data. The pairs of the groups are organized such that a first pair includes the first and second groups, a second pair includes the third and fourth groups, and a third pair includes the fifth and sixth groups. The optical fibers of the groups are sized and routed to facilitate low-skew and efficient parallel optics connections for high-speed data transmission.

  • Patent number: 8639082
    Abstract: A fiber optic cable assembly includes a connector that has a mating end and a cable end. A fiber optic cable is terminated to the cable end of the connector. A cable director is coupled to the fiber optic cable rearward of the connector. The cable director includes a flexible support sleeve and a clip extending from the support sleeve. The support sleeve includes a raceway that receives the fiber optic cable. The support sleeve has a first end segment and a second end segment. The support sleeve has a first attachment point proximate to the first end segment and a second attachment point proximate to the second end segment. The support sleeve is held in a bent shape when the clip is attached to both the first attachment point and the second attachment point. The support sleeve is configured to be straightened to a loading position in which the raceway is substantially linear when the clip is removed from at least one of the first or second attachment points.

  • Patent number: 8634689
    Abstract: A telecommunications module includes a main housing portion and a cover, the main housing portion defining a first sidewall, a front wall, a rear wall, a top wall, and a bottom wall, the cover defining a second sidewall when mounted on the main housing portion. An optical component located within the module receives an input signal from a signal input location of the housing and outputs an output signal toward a signal output location on the front wall. The telecommunications module is configured such that the signal input location can be selected to be either on the front wall or the rear wall of the main housing. The cover defines a protrusion extending from the second sidewall toward the main housing portion, the protrusion being selectively breakable to expose a recess on the front wall of the main housing portion that defines a signal input location.

  • Patent number: 8625952
    Abstract: Fiber optic cable mounting adapters and related fiber optic cable assemblies and methods for attaching an external mounting device to the fiber optic cable are disclosed. The fiber optic mounting adapters can be configured to be secured to a portion of a fiber optic cable. The fiber optic mounting adapters can also be configured to be secured to external mounting devices compatible to be secured to fiber optic equipment, to secure the fiber optic mounting adapter, and in turn the fiber optic cable, to the fiber optic equipment. Securing a portion of a fiber optic cable can reduce or prevent bending strain from being propagated along the fiber optic cable. Undesired bending strain of a fiber optic cable can cause undesired optical attenuation. Bending strain can also risk damaging optical fibers, such as furcated legs, exposed from the end portion of the fiber optic cable.

  • Patent number: 8625953
    Abstract: An optical fiber ribbon holding member capable of readjusting a position of an optical fiber ribbon without requiring a heating operation is provided. A holding member main body that has a U-shaped cross section and a space to which a plurality of optical fiber ribbons can be accommodate in a laminated state, and a lid body an opening surface of which has a reverse U-shaped cross section are employed. A latch structure is formed on wall portions of a lid body and a holding member main body, and engages to each other when the lid body covers the holding member main body. Heating operation is not required, and the optical fiber ribbons are held by only a simple operation of covering the lid body, so that the operation of holding the optical fiber ribbons is easily performed and readjustment of the position of the optical fiber ribbons can be performed.
