Abstract: A system for delivering multiple passive optical network services is disclosed. The system includes a first optical transmission service comprising a common wavelength pair routed from a source to each of a plurality of subscribers. The system further includes a second optical transmission service comprising a plurality of unique wavelength pairs, where each of the unique wavelength pairs is routed from the source to a subscriber among the plurality of subscribers. The system delivers the first optical transmission service and the second optical transmission service to the subscriber on a single optical fiber.

Abstract: An optical power detection system comprises a sensor and a reader. The sensor is configured to detect light in the cladding of an optical fiber. The sensor is positioned both within a ferrule of the optical fiber and proximate the cladding. The sensor is additionally configured to produce an output signal representative of the detected light. The reader is electrically coupled to the sensor and is configured to receive the sensor output signal. The reader is additionally configured to operation on the output signal to produce a corresponding visual and/or audible indication of the optical power in the optical fiber.

Abstract: A fiber optic and electrical connection system includes a fiber optic cable, a ruggedized fiber optic connector, a ruggedized fiber optic adapter, and a fiber optic enclosure. The cable includes one or more electrically conducting strength members. The connector, the adapter, and the enclosure each have one or more electrical conductors. The cable is terminated by the connector with the conductors of the connector in electrical communication with the strength members. The conductors of the connector electrically contact the conductors of the adapter when the connector and the adapter are mechanically connected. And, the conductors of the adapter electrically contact the conductors of the enclosure when the adapter is mounted on the enclosure.

Abstract: 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, spare ports can be providing in a forward direction and reverse direction ports can also be provided.

Abstract: 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.

Abstract: A telecommunications assembly includes a chassis and a plurality of fiber optic splitter modules mounted within the chassis. Each splitter module includes at least one fiber optic connector. Within an interior of the chassis are positioned at least one fiber optic adapter. Inserting the splitter module through a front opening of the chassis at a mounting location positions the connector of the splitter module for insertion into and mating with the adapter of the chassis. The adapters mounted within the interior of the chassis are integrally formed as part of a removable adapter assembly. A method of mounting a fiber optic splitter module within a telecommunications chassis is also disclosed.

Abstract: 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.

Abstract: An optical fiber cable management panel includes drawer assemblies, each including a drawer slidable within a chassis. The drawer assemblies are secured together by a bracket that includes an interlock arrangement with the chassis. Such an interlock arrangement includes a non-threaded stud engaging a hole. Radius limiters may be part of the drawer assembly and include a cable entry aperture have a closed perimeter and a flared cable guide surface around most of, and preferably all of, the closed perimeter to allow for the entry of cables from all directions. A control mechanism controls movement of the radius limiter relative to the drawer assembly. The control mechanism includes a rotating member that has an axis of rotation transverse to the slidable motion of the radius limiter and normal to the radius limiter.
