20090022460Factory Spliced Cable Assembly - A telecommunications cable including a main cable having a central buffer tube enclosed within a cable jacket and a ribbon stack positioned within the buffer tube. The main cable includes a cut region where a slot has been cut through the cable jacket and the buffer tube to provide access to the ribbon stack during manufacture of the telecommunication cable. A tether branches from the main cable at the cut region. The tether includes an optical fiber that is optically coupled to an optical fiber of the ribbon stack.01-22-2009
20090123115Drop Terminal Releasable Engagement Mechanism - A terminal for mounting to a fiber distribution cable includes a base and a cover releasably engaged to the base by a releasable engagement mechanism. The releasable engagement mechanism includes a resilient latch having a base end and a free end. The free end defines a plurality of openings. The releasable engagement mechanism further includes a plurality of protrusions having a lip and a sloped surface. The plurality of protrusions is adapted for engagement with the plurality of openings of the resilient latch.05-14-2009
20090148118Mini Drop Terminal - A terminal for mounting to a fiber distribution cable includes a housing having a base and a cover. The cover is connectedly engaged with the base. The terminal further includes a plurality of adapters disposed on the cover. A fiber routing tray having a top panel and a bottom panel is disposed in an interior cavity. The fiber routing tray includes a storage space defined between the top and bottom panels for storing a length of optical fiber. A method for installing a terminal includes providing a terminal having a housing defining an interior cavity. A cable is pulled from the interior cavity of the housing. The cable is spliced to a fiber distribution cable with a splice. The cable is inserted back into the interior cavity. A spliced end of the cable, a spliced end of the fiber distribution cable and the splice are inserted in a retention device.06-11-2009
20090202214WALL BOX ADAPTED TO BE MOUNTED AT A MID-SPAN ACCESS LOCATION OF A TELECOMMUNICATIONS CABLE - The present disclosure relates to a wall box adapted to be mounted at a mid-span access location of a fiber optic telecommunications cable. The wall box includes an enclosure having a main body with an open front side. The enclosure also includes a front cover for opening and closing the open front side of the main body. The wall box defining first and second cable entrance/exit openings positioned at opposite sides of the enclosure. The main body defines an open region through an exterior wall of the main body. The open region extends from the first cable entrance/exit opening to the second cable entrance/exit opening. The enclosure also includes a cable cover that is mounted to the main body to cover the open region. The cable cover is a separate component from the front cover.08-13-2009
20090238531WALL BOX ADAPTED TO BE MOUNTED AT A MID-SPAN ACCESS LOCATION OF A TELECOMMUNICATIONS CABLE - A wall box includes an enclosure having a base and a cover connected to the base. The base and the cover enclose an interior region. The wall box further includes a plurality of fiber optic adapters mounted to the enclosure. The fiber optic adapters include an inner port positioned inside the interior region and an outer port positioned at an outer surface of the enclosure. A tray stack is mounted within the interior region. The tray stack includes a tray mount pivotally connected to the enclosure. The tray mount includes a top surface and an oppositely disposed bottom surface. A first splice tray mounting area is disposed on the top surface and a second splice tray mounting area is disposed on the bottom surface. A plurality of trays is disposed in the first splice tray mounting area. A tray is disposed in the second splice tray mounting area.09-24-2009
20090269020DROP TERMINAL WITH ANCHOR BLOCK FOR RETAINING A STUB CABLE - The drop terminal includes a plurality of fiber optic adapters having outer connector ports that are accessible from outside the drop terminal. The drop terminal receives a fiber optic cable having a plurality of optical fibers. Fiber optic connectors are positioned at the ends of the optical fibers. The fiber optic connectors are inserted into inner connector ports of the fiber optic adapters. The drop terminal also includes an anchor block for securing the fiber optic cable to a main housing of the drop terminal. The anchor block can be secured to the main housing of the drop terminal by a mechanical interlock. The drop terminal may also include a transparent interior shield or liner that retains fibers in position within the drop terminal during assembly of the drop terminal.10-29-2009
20090297112FIBER ACCESS TERMINAL - A fiber access terminal for mounting to the end of a fiber distribution cable and configured to be extended through a buried conduit. The fiber distribution cable may include a plurality of optical fibers and enters a housing of the terminal through a base. The terminal also includes a plurality of fiber optic connectors or adapters extending through the housing in generally the same direction as the fiber distribution cable for connecting to optical fiber customer drop cables. The terminal includes a cover and the housing defining an interior and the interior includes a cable slack storage arrangement providing bend radius protection for the optical fiber cables within the interior. A method of assembling a fiber access terminal. A fiber access terminal assembly including a pedestal mounting arrangement.12-03-2009
20100027954Cable Enclosure with Sealed Cable Entry Port - This disclosure describes a fiber optic enclosure in which a cable entry port is sealed using a wedge that compresses a gasket that surrounds a fiber optic cable. As described herein, a fiber optic enclosure may include one or more entry ports through which fiber optic cables pass. As one of the fiber optic cables passes through one of the entry ports, the fiber optic cable passes through a gasket located in a receptacle behind the cable entry port. A wedge compresses the gasket, thereby compressing the gasket. When the gasket is compressed, the gasket exerts radial pressure on the fiber optic cable. In this way, the gasket forms a seal around the fiber optic cable.02-04-2010
20100303433DROP TERMINAL WITH ANCHOR BLOCK FOR RETAINING A STUB CABLE - The drop terminal includes a plurality of fiber optic adapters having outer connector ports that are accessible from outside the drop terminal. The drop terminal receives a fiber optic cable having a plurality of optical fibers. Fiber optic connectors are positioned at the ends of the optical fibers. The fiber optic connectors are inserted into inner connector ports of the fiber optic adapters. The drop terminal also includes an anchor block for securing the fiber optic cable to a main housing of the drop terminal. The anchor block can be secured to the main housing of the drop terminal by a mechanical interlock. The drop terminal may also include a transparent interior shield or liner that retains fibers in position within the drop terminal during assembly of the drop terminal.12-02-2010
