摘要： The present disclosure relates to a fiber optic network architecture that uses outside plant fan-out devices to distribute optical signals between fiber distribution hubs and multi-service terminals. The network architecture can also include collector boxes positioned at selected locations of the network architecture. Additionally, patching systems can be used in facilitating upgrading the capacity of the fiber optic network.

摘要： A passive optical network includes a central office providing subscriber signals; a drop terminal; and a wave division multiplexer. A fiber distribution hub may split or separate out dedicated optical signals from subscriber optical signals between the central office and the drop terminal. The wave division multiplexer separates dedicated optical signals pertaining to a specific dedicated subscriber from other optical signals on the line received at the wave division multiplexer. The wave division multiplexer may be part of a cable or part of an intermediate service terminal.

摘要： A cable spool includes first and second curved flanges extending radially outwardly from first and second axial ends of a drum. The flanges have outer edges that cooperate to define an annular slot providing access to a passageway surrounding the drum. The slot has a width that is less than half the height of the drum. A cable is wrapped around the drum. A closure having an environmentally sealed interior may receive an end of the cable. A second cable can be deployed from a second spool and coupled to the end of the cable within the closure. The second spool can be mounted with the cable spool. A cover can be placed over the spools for aesthetic or protection reasons.

摘要： Packaged dispensers mountable to optical network terminals (ONT) are disclosed. In some examples, the dispensers include coreless wound coils and excess storage areas. Additionally, fiber optic cable distribution systems and methods thereof utilizing the disclosed coreless wound coils are further disclosed. In one example, a length of telecommunications cable is wound into a coreless coil that includes a plurality of winding separators at least partially embedded within the coil, wherein the length of telecommunications cable alternately passes on one of the first and second sides of one winding separator and on the other of the first and second sides of an adjacent winding separator. In one example, an initially cylindrically shaped coreless wound coil, with or without winding separators, can be placed into a non-round package in which the wound coil is deformed and compressed by the sidewalls of the package such that the coreless wound coil conforms to the interior perimeter of the package to have a non-cylindrical shape.

摘要： The present disclosure relates to systems and method for deploying a fiber optic network. Distribution devices are used to index fibers within the system to ensure that live fibers are provided at output locations throughout the system. In an example, fibers can be indexed in multiple directions within the system. In an example, fibers can be stored and deployed form storage spools.

摘要： Systems and methods for delivering multiple passive optical network services are disclosed. One system includes a first optical transmission service comprising a common wavelength pair routed from a source to each of a plurality of subscribers and a second optical transmission service comprising a plurality of unique wavelength pairs, each of the unique wavelength pairs assigned to a subscriber among the plurality of subscribers. The system includes a splitter optically connected to first fiber carrying the first optical transmission service, the splitter including a plurality of outputs each delivering the first optical transmission service, and a wavelength division multiplexer connected to a second fiber, the wavelength division multiplexer separating each of the unique wavelength pairs of the second optical transmission service onto separate optical fibers. The system further includes a plurality of second wavelength division multiplexers optically connected to a different output of the plurality of outputs of the splitter and to a different one of the unique wavelength pairs from the wavelength division multiplexer, thereby combining a unique wavelength pair and a common wavelength pair onto a single fiber to be delivered to a subscriber.

摘要： 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.

摘要： A passive optical network includes a central office providing subscriber signals; a fiber distribution hub including an optical power splitter and a termination field; and a drop terminal. Distribution fibers have first ends coupled to output ports of a drop terminal and second ends coupled to the termination field. A remote unit of a DAS is retrofitted to the network by routing a second feeder cable from a base station to the hub and coupling one the distribution fibers to the second feeder cable. The remote unit is plugged into the corresponding drop terminal port, for example, with a cable arrangement having a sealed wave division multiplexer.
