Providing high-density port tap fiber optic modules can support greater connection bandwidth capacity to provide a migration path for higher data rates while minimizing the space needed for such fiber optic equipment. | 2018-06-07 |
20180157000 | FIBER OPTIC CABLE MANAGEMENT SYSTEM - A fiber optic cable management system includes a tray configured to reciprocate inside of an enclosure between an inserted position and an extended position. Optical fiber modules are located in the tray and retain optical fiber splitters or optical fiber multiplexer/de-multiplexers. The tray when moved to the extended position moves the optical fiber modules out of the front end of the rack enclosure. This allows a technician to access the back of the modules for maintenance operations without having to access the back end of the enclosure. A flexible cable guide allows the optical fibers connected to the modules to move with the tray into and out of the enclosure. Reflectors can be attached to the connectors to test fiber optic lines between a central office and the cell site location. | 2018-06-07 |
20180157001 | Optical Bridge Between Exterior And Interior Networks - A method includes receiving an optical signal from an external network at a first optical terminal affixed to an external side of a substantially transparent surface of a building. The first optical terminal includes a first fiber port configured to receive a first optical fiber and an output lens optically coupled to the first fiber port. The first fiber port is configured to route the optical signal from the external network to first optical terminal. The method also includes directing the optical signal through an optical link extending through the substantially transparent surface to a second optical terminal affixed to an interior side of the substantially transparent surface. The second optical terminal includes an input lens and a second fiber port optically coupled to the input lens. The input lens is configured to receive the optical signal from the first optical terminal through the optical link. | 2018-06-07 |
20180157002 | OPTICAL TERMINATION ENCLOSURE - The present disclosure relates to an optical termination enclosure having an enclosure housing containing a fiber management assembly. The enclosure housing can define sealed cable ports and can include cable anchor mounting locations in alignment with the cable ports. Cable anchoring and grounding units can be attached at the cable anchor mounting locations. The fiber management assembly can include a fiber break-out arrangement including a resilient grommet used to anchor a protective tube that carries optical fibers from the cable anchor mounting location to the fiber management assembly. | 2018-06-07 |
20180157003 | IMAGE FORMING APPARATUS - An apparatus includes a control portion. When a toner image formed on a first recording material is fixed onto the first recording material by the fixing portion, and then an image is formed on a second recording material of which width is larger than that of the first recording material, the control portion can execute a cooling sequence to cool a non-passing region of the fixing portion through which the second recording material passes but the first recording material does not pass, before the toner image formed on the second recording material is fixed by the fixing portion. The control portion sets an execution condition to execute the cooling sequence in accordance with information on the toner image in the region of the second recording material corresponding to the non-passing region. | 2018-06-07 |
