  • Patent number: 8488935
    Abstract: It is determined that service is to be disconnected for at least a first subscriber of a video content network employing at least one fiber optic cable. The service to the at least first subscriber is provided from a cross-connect cabinet, over the at least one fiber optic cable, to a premises of the at least first subscriber. Sufficient macro-bending loss is induced in the at least one fiber optic cable so as to cause a signal-to-noise ratio at the premises to degrade such that the service is disconnected. The macro-bending loss is induced in a portion of the at least one fiber optic cable which services only the first subscriber. The macro-bending loss can be induced, for example, by winding about a single mandrel, two mandrels in a figure eight pattern, in a tortuous groove in a tray, and so on.

  • Patent number: 8355616
    Abstract: An installing method of an optical fiber communication conversion device is provided. The installing method includes the following steps. Firstly, a housing is provided. An opto-electronic converting module with a first cable winding structure is selectively accommodated and installed within the housing. An optical fiber wiring process is performed. If the opto-electronic converting module is provided and installed within the housing, an optical fiber cable managing function is implemented by the first cable winding structure. If the opto-electronic converting module is not installed within the housing, the optical fiber cable managing function is implemented by a second cable winding structure within the housing. The optical fiber communication conversion device using the installing method is also provided.

  • Patent number: 8340491
    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: 8331754
    Abstract: A fiber optic strain relief device is provided. The device has a base that attaches to a piece of equipment and/or hardware. A length of strap positions in the base and forms a loop. The loop is adapted to at least partially encircle a portion of a cable positioned at the base. A strap tightener incrementally shortens the length of the strap, reducing the loop and tightening the strap around the cable. The strap tightener may be a ratchet assembly comprising an actuator, a ratchet cap, a pin, a ratchet lock and a release. The length of strap inserts into a slot in the pin. The ratchet assembly operates to tighten the length of strap encircling the portion of the cable by incrementally rotating the pin. The release allows the strap to be loosened around the fiber optic cable.

  • Patent number: 8319120
    Abstract: A spillover fitting is positioned on an upstanding side of a lateral cable trough. The spillover fitting includes a first exit path having a first curved surface that extends at least partially over a base of the lateral cable trough, and a bottom wall having a second curved surface intersecting with the first curved surface. The first surface curves upward relative to the base of the lateral cable trough and defines a top surface of a cable path, and the second surface is convexly curved and defines a bottom surface of the cable path. The radius of curvature of the first curved surface is equal to the radius of curvature of the second curved surface.
