摘要： The invention is directed to a system and method for troubleshooting in an optical data network that has a laser transmitter/receiver unit that outputs a data signal and an OTDR unit that produces an OTDR probe signal. The data and OTDR probe signals, typically at different wavelengths, are coupled into one end of a trunk fiber which is coupled at its far end to an optical circuit that includes a number of wavelength-selective optical switches and has multiple outputs that are directed to different end users. The optical switches are configurable so as to provide the OTDR probe signal to only one of the optical circuit's outputs while maintaining the data signal at the same output, while also maintaining the data signal, without the OTDR probe signal, at other outputs.

摘要： A gel sealing device includes a gel sealing block (5) which provides a sealing section (22) through which the elongate parts (13, 14) extend. The gel sealing block (5) includes an upper flange (11) and a lower flange (12) with a support section (11a, 12a, 12b) disposed therebetween. The upper and lower flanges (11, 12) sandwiches, in direction of extension of the elongate parts (13, 14), a gel inner ring (7) supported by said support section (2) and a gel outer ring (6, 10a) covering the gel inner ring (7) in a radial direction extending transverse to said extension direction. The gel inner ring (7) and the gel outer ring (6, 10a) are made of a gel sealing material.

摘要： A hybrid cable distribution system wherein a feeder cable is received by a box. The feeder cable can be a hybrid cable including optical fibers and copper wire (coax). The box may be used only for copper signal handling (such as coaxial signal handling), and then at a later date, the box may be used for receiving fiber signals. Customers can directly connect to the feeder fan out device by connecting a tail of a drop splice module that is spliced to an individual distribution cable to the feeder fan out device. This connection creates a point-to-point connection. The number of fan out devices in the system can be increased or decreased as needed. Alternatively, a splitter input can be connected to the feeder fan out device, such as through a pigtail extending from the splitter, wherein the splitter splits the signal as desired into a plurality of outputs. The outputs of the splitters can be in the form of connectors or adapters. The connectors or adapters are then connected to tails of drop splice modules that are spliced to individual distribution cables so that customers can receive a split signal. The cable distribution system allows for mixing of connection types to the customer(s) such as a direct connection (point-to-point), or a split signal connection. Further, the types of splitters can be mixed and varied as desired. Further, the types of fan out devices can be mixed and varied as desired.

摘要： A cable fixation bracket and methods for securing cables to a cable fixation bracket are disclosed. The cable fixation bracket can include a base portion extending between a pair of mounting structures. A plurality of t-shaped cable fixation projections extending orthogonally from the base portion can be provided, each of which is configured to support a cable and to accept a cable tie. In some examples, the fixation projections are tapered. The cable fixation bracket can also include a bridge portion supporting a plurality of bracket structures for anchoring aramid yarn of the cables. The bracket structures are configured such that aramid yarn of the cables can be wrapped around the bracket structures and returned to the fixation projections or such that the aramid yarn can be wrapped about a termination unit with the termination unit being mounted between a pair of adjacent cable structures.

摘要： A hinge structure (2202) for pivotally mounting a first telecommunications element (2256) to a second telecommunications element (2224/2210) includes a hinge pin (2203) provided on the first element (2256) and a hinge pin receiver (2204) provided on the second element (2224/2210). The hinge pin (2203) defines a notch (2206) separating the pin (2203) into two pin halves (2205). The hinge pin receiver (2204) defines two sets of opposing surfaces (2214), the two sets (2214) separated by a divider (2212), the divider (2212) configured to be accommodated by the notch (2206) when the hinge pin (2203) is inserted into the hinge pin receiver (2204), wherein each opposing surface set (2214) defines a slot (2213) for receiving each pin half (2205).

摘要： The present disclosure relates to a ruggedized/hardened fiber optic connection system designed to reduce cost. In one example, selected features of a fiber optic adapter are integrated with a wall (24) of an enclosure (22). The adapter comprises a sleeve port (26) into which an optical adapter subassembly is inserted. The subassembly comprises a sleeve part (44) which is inserted into the sleeve, a ferrule alignment sleeve (48) which is inserted into the sleeve part, a ferrule (55) with hub which is inserted into the alignment sleeve, and fixing clip (46) securing the ferrule with hub into the alignment sleeve and the sleeve part.

摘要： A clamp assembly includes a first clamp half-piece and a second clamp half-piece. In one example, the clamp half-pieces are identically shaped. In one example, each of the clamp half-pieces has at least one integral pin and at least one aperture. The first and second clamp half-pieces are pivotally connected to each other via a first snap-fit interface in which the integral pin of the first clamp half-piece snap-fits into the at least one aperture of the second clamp half-piece. The clamp assembly can also include a link arm connected to the first clamp half-piece via a second snap-fit interface. A lever arm can also be included that is pivotally connected to the link arm via a third snap-fit interface. The clamp assembly does not require separate link pins or other parts and only includes four components: the clamp half-pieces, the link arm, and the lever arm.

摘要： Example fiber optic connector systems have rugged, robust designs that are environmentally sealed and that are relatively easy to install and uninstall in the field. Some connector systems can be configured in the field to be compatible with different styles of fiber optic adapters. Some connectors include a first seal (90) on a release sleeve; and a second seal (88) between the release sleeve and a connector body. Other connectors include a seal (139) and a flexible latch (136) on a connector. Other connectors include a protective structure (228, 328, 428) that mounts over the fiber optic connector. Other connectors include a protective outer shell (528, 860) and a sealing and attachment insert (570, 570A, 876). Other connectors include a protective outer shell (728) and a fastener (780).

摘要： A system for monitoring a signal on an optical fiber includes a fiber optic connector having a housing couplable to a receptacle. An optical fiber that transmits a first optical signal has first fiber core at least partially surrounded by a cladding and has a first end terminating proximate the housing. The first optical signal is transmitted along the first fiber core. An optical tap has a first tap waveguide arranged and is configured to receive at least part of the first optical signal as a first tap signal. The first tap waveguide comprises an output port for the first tap signal for directing the tap signal to a detector unit. In other embodiments, a detector unit detects light from the optical signal that is propagating along the fiber cladding.
