Fiber optic networks having a self-supporting optical terminal along with methods of installing the optical terminal are disclosed. The fiber optic network comprises an optical terminal having a housing and a tether cable attached to the housing. The tether cable is aerially supported by the tether cable of the optical terminal using a cable clamp. The fiber optic networks can aerially deploy the self-supporting optical terminal without the use of a support strand and lashing like conventional optical terminals since the optical terminal is light-weight and has a small form-factor. The tether cable may be attached to one or more mounting features of the housing and the cable clamp grips a portion of the tether cable for the aerial installation.

An optical fiber feed-through connector for optically coupling an end portion of an optical fiber cable with a non-feed-through optical fiber connector includes a feed-through duct engaging portion having a body member and a compression fitting portion configured to radially compress a portion of the body member around the free end portion of the duct and a feed-through housing portion configured to be operatively coupled to the feed-through duct engaging portion so as to allow the end portion of the optical fiber cable to be slidingly fed through the feed-through housing portion. The feed-through engaging portion is configured to permit the end portion of the optical fiber cable to be slidingly fed through both the duct and the feed-through duct engaging portion, and the feed-through duct engaging portion and the feed-through housing portion are configured to permit the optical fiber cable to be pushed or pulled through the duct and the feed-through housing portion after the feed-through duct engaging portion is operatively coupled to the feed-through housing portion.

A terminal enclosure with a terminal base with a hole; a terminal lid with an adapter mounting face and a mounting hole in the mounting face; a right angle transition body with first and second ends; an adapter which passes through the mounting hole and is mounted to the mounting face; and a fiber optic cable, attached to the second end of the right angle transition body, with an optical fiber with a connector at one end. The mounting face is formed at an angle α, between 0 and 180 degrees, from a plane formed where the terminal lid and base meet. The optical fiber connector is connected to the adapter. The first end of the right angle transition body passes through the terminal base hole. The terminal base and terminal lid are configured to be attached together.

The present disclosure relates a telecommunication enclosure having a compact configuration. In one example, the telecommunication enclosure supports both optical splicing and connectorized patching.

Disclosed is a TMS for an optical fiber remote control submersible, including an upper cylinder equipped with a counterweight and a lower cylinder equipped with a buoy; the upper cylinder and the lower cylinder are sleeved with each other, and matched electromagnets and iron plates are respectively installed in the two parts; the upper cylinder is connected with a mother ship through a light armoured optical power cable, and the light armoured optical power cable may provide electric power for the electromagnets, and the lower cylinder is connected with a submersible through a light load-bearing optical fiber cable; and an end of the light armoured optical power cable inside the upper cylinder is optically connected with an end of the light load-bearing optical fiber cable inside the lower cylinder.

An optical shape sensing (OSS) system includes a launch fixture configured to receive and secure an optical fiber within a flexible OSS enabled instrument, where the launch fixture includes a docking interface; a launch fixture base configured to be connected to a support structure; and a docking device configured to secure the launch fixture onto the launch fixture base. The docking device includes a launch fixture slot passing through the docking device, and the launch fixture slot is configured to receive and secure the docking interface of the launch fixture through both a top side of the docking device and an opposing bottom side of the docking device.

A fiber optic tray system includes a tray. The tray includes a tray body, the tray body extending along a longitudinal axis between a front and a rear and extending along a lateral axis between a first side and a second side. The tray further includes a plurality of alignment rails, each of the plurality of alignment rails protruding from the tray body along a transverse axis. The tray further includes a plurality of retainer features disposed at the rear of the tray body. The fiber optic tray system further includes a fiber optic module, the fiber optic module including an outer housing and at least one retainment feature. The at least one retainment feature is interfaced with at least one of the plurality of retainer features to retain the fiber optic module on the tray.

A module for optical fiber installation and storage at customer premises has a base, and a fiber supply spool mounted for rotation on the base. An elongated adapter plate has a front end portion for mounting a connector adapter. A rear end portion of the adapter plate has first hinge parts at one side of the plate, and the fiber supply spool has second hinge parts for engaging the first hinge parts of the plate to define a hinge axis. The adapter plate can swivel about the hinge axis between a position where the plate lies flush on the supply spool and the spool can turn as fiber unwinds, and a position where a port of a connector adapter mounted on the plate is accessible for connection to an outside device when the module is closed, and the plate engages the module base to restrain the spool from rotation.

Certain types of fiber termination enclosures include an enclosure and at least one of a plurality of plate module mounting assemblies. Example plate module mounting assemblies include a termination panel plate assembly; a splice tray plate assembly; a cable spool plate assembly; and a drop-in plate assembly. Example cable spool plate assemblies include a cable spool arrangement rotationally coupled to a mounting plate, which fixedly mounts within the enclosure housing. A stand-off mount element may be disposed on the front of the cable spool arrangement to rotate in unison with the cable spool arrangement. The stand-off mount element may include one or more termination adapters.

A fiber optic splice enclosure includes a basket. The basket includes an outer shell, the outer shell including an outer sidewall defining at least a portion of a periphery of the basket. The basket further includes an insert disposed within the outer shell, the insert including a first sidewall and a second sidewall spaced apart from each other along a transverse axis and each extending along a longitudinal axis to define an inner channel therebetween. The first sidewall and the second sidewall are each further spaced apart from the outer sidewall along the longitudinal axis to define a first outer channel and a second outer channel. The fiber optic splice enclosure further includes a splice tray assembly including at least one splice tray, the splice tray assembly disposed within the inner channel.
