A device for making optical connections comprising a shell, at least one connection port, and at least one rotating securing feature is disclosed. In one embodiment, the at least one connection port is disposed on a device with at the least one connection port comprising an optical connector opening extending from an outer surface of the device into a cavity of the device and defining a connection port passageway.

Provided is an optical fiber which has exceptional heat resistance and is highly safe. This optical fiber has a core, and a sheath of a least one layer around the outside circumference of the core, the sheath including a polymer that contains a repeating unit (A) derived from a fluoroalkyl (meth)acrylate having a specific structure.

The present disclosure provides a pitch reducing optical fiber array or a multicore fiber including at least one chiral fiber grating incorporated therein that is operable to couple the modes in different fiber cores within a spectral range determined in some instances by the helical pitch of the corresponding chiral fiber grating.

Also described are radiation curable coating compositions possessing reduced thermal sensitivity, methods of coating such radiation curable coating compositions to form coated optical fibers, and optical fiber cables comprising the coated optical fibers and/or radiation curable coating compositions elsewhere described.

Tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a corrosion resistant metallic alloy. However, pumping during the installation of tubing encapsulated cable is required to overcome the capstan effect of the tubing encapsulate cable inside the coil tubing as the tubing encapsulated cable travels through the coiled up wraps of coil tubing. In an embodiment of the invention the tubing encapsulated cable consists of one or more electrical conductors and possibly one or more fiber optic cables sheathed in a fiber reinforced composite sheath. Because there is little drag between the fiber encapsulated cable and the coil tubing, conventional pumping operations used to install braided wireline into coil tubing may not be required when installing fiber encapsulated cable into coil tubing. Additionally, the smooth outside surface and relatively small diameter of the fiber encapsulated cable are desirable attributes for well intervention work because the smooth surface is more resistant to chemical attack than braided wire while the smooth surface and relatively small diameter provide little viscous drag while fluids are pumped through the coil tubing in the course of intervention operations.

Methods, systems, and apparatuses that facilitate installation of a communications cable, e.g., an optical fiber cable, are disclosed. The system may include a communications cable and an adhesive for securing the cable to a surface. The method may include the use of an adhesive to secure the communications cable to a surface. The apparatus may include a pathway to avoid over-bending of the communications cable, which may otherwise result in transmission loss and compromise the performance of the cable.

Embodiments include an optical fiber cable comprising a length extending between a first end and a second end, a central cooling tube, a plurality of optical fibers disposed radially around the cooling tube, each optical fiber comprising a fiber core and a cladding disposed around the fiber core, an outer protective cover, and an inner thermal filler disposed between the outer protective cover and the central cooling tube and surrounding each of the optical fibers, wherein each of the central cooling tube, the outer protective cover, the inner thermal filler, and the plurality of optical fibers extend the length of the cable. Various systems and methods for removing imperfections from individual optical fibers and for distributing power across long distances using the optical fiber cable are also provided.
