Abstract: The present disclosure relates to a fiber optic network configuration having an optical network terminal located at a subscriber location. The fiber optic network configuration also includes a drop terminal located outside the subscriber location and a wireless transceiver located outside the subscriber location. The fiber optic network further includes a cabling arrangement including a first signal line that extends from the drop terminal to the optical network terminal, a second signal line that extends from the optical network terminal to the wireless transceiver, and a power line that extends from the optical network terminal to the wireless transceiver.

Abstract: An optical fiber testing device (300) being plugged into a port at which optical signals including communication and test signals within different wavelength bands being received, comprises an optical connector (304) including a plug body surrounding a ferrule holding an optical fiber (301) and a reflector component (326) carried with the optical connector (304). The reflector component (326) is optically coupled to the rear of the optical fiber and reflects the test signal. A method for testing an optical fiber, comprises removably securing a reusable ruggedized optical fiber testing device to a ruggedized port of an optical fiber terminal to optically couple to an optical fiber under test, transmitting a test signal over the optical fiber under test, and using the reflector component to return the test signal over the optical fiber under test when receiving the test signal.

Abstract: The present disclosure relates to a fiber optic connector for use with a fiber optic adapter. The fiber optic connector includes a connector housing having an end defining a plug portion. A ferrule assembly is mounted at least partially within the connector housing. The ferrule assembly includes a ferrule located at the plug portion of the connector housing. A sealing member is mounted about an exterior of the connector housing for providing a seal between the connector housing and the adapter. The fiber optic connector further includes first and second separate retaining mechanism for retaining the fiber optic connector within the fiber optic adapter.

Abstract: The present disclosure relates to a splice arrangement. The splice arrangement may include an elongate splice protection housing that defines a channel that extends lengthwise through the elongate splice protection housing from a first end of the splice protection housing to an opposite second end of the splice protection housing. The splice arrangement may also include a first fiber optic cable and a second fiber optic cable. First optical fibers of the first fiber optic cable and second optical fibers of the second fiber optic cable may be coupled together at a splice location positioned within the channel of the elongate splice protection housing.

Abstract: Optical connector arrangements terminate at least seventy-two optical fibers. The optical connector arrangements include multiple optical ferrules that each terminates multiple optical fibers. Some example optical connectors can terminate about 144 optical fibers. Each optical connector includes a fiber take-up arrangement and a flange extending outwardly from a connector housing arrangement. The fiber take-up arrangement manages excess length of the optical fibers. A threadable coupling nut can be disposed on the connector housing arrangement to engage the outwardly extending flange. Certain types of optical connector arrangements include furcation cables spacing the connector housing arrangement form the fiber take-up arrangement.

Abstract: The present disclosure includes a fiber optic cable having a conduit including a conduit wall defining a conduit passage that extends longitudinally through the conduit. The conduit also includes an adhesive injection port defined through the conduit wall and at least one optical fiber within the conduit passage. The cable further includes a fiber lock including an adhesive volume in communication with the adhesive injection port. The adhesive volume includes a main adhesive volume positioned within the conduit passage and bonded to the optical fiber. The main adhesive volume is fixed to prevent longitudinal movement relative to the conduit.

Abstract: A fiber optic cable assembly includes a fiber optic cable and a fiber optic connector. The cable includes a jacket having an elongated transverse cross-sectional profile that defines a major axis and a minor axis. Strength components of the cable are anchored to the connector. The fiber optic connector includes a multi-fiber ferrule defining a major axis that is generally perpendicular to the major axis of the jacket and a minor axis that is generally perpendicular to the minor axis of the jacket. Certain types of connectors include a connector body defining a side opening that extends along a length of the connector body; a multi-fiber ferrule configured for lateral insertion into the connector body through the side opening; and a cover that mounts over the side opening after the multi-fiber ferrule has been inserted into the connector body through the side opening.

Abstract: A fiber optic network architecture for distributing service to local subscribers is disclosed. The architecture includes a plurality of high-fiber count cables connected end-to-end at connectorized coupling locations to form a main cable trunk. The connectorized coupling locations include high-fiber count pass-through connections for optically connecting optical fibers of adjacent ones of the high-fiber count cables end. The connectorized coupling locations also including high-fiber count branch connections for optically connecting optical fibers of the high-fiber count cables to branch locations.
