An apparatus has a chassis having a base. A first wall extends substantially perpendicularly from the base at a first edge of the base. The first wall is configured to be a first attachment point for an optical cable comprising one or more optical sensors. An opposing second wall extends substantially perpendicularly from the base at a second edge of the base. A mobile attachment point is configured to be a second attachment point for the optical cable. A spring is coupled to the second wall and the mobile attachment point. The spring is configured to provide a specified force as the mobile attachment point moves.

The invention relates to an optical light guiding system, comprising an interface for coupling in and/or an interface for decoupling data and at least one data channel for transmitting data, and a method for transmitting data in optical systems, comprising the steps of coupling data into an interface of a beam guidance element; the transmission of the data by means of a first and/or a second data channel, which are arranged within the beam guiding element (or the casing), wherein the data channels can also be used for the fractional monitoring of the beam guiding element; and decoupling the data from an interface.

An optical fiber cable is composed of an optical fiber core, a tension member, an outer sheath, and so forth. The optical fiber core includes a glass wire and a resin-coated part, which is further coated by a transparent member on its outer periphery. The transparent member is, for example, urethane acrylate, PVC, nylon, and so forth. The transparent member preferably has a total light transmittance, defined by JIS K7361-1, of 60% or higher. The reason is that when the total light transmittance is less than 60%, the color tone of the optical fiber core (transparent member) becomes intense and stands out. Additionally, it is preferable that the total light transmittance of the transparent member is 80% or more.

An indoor cable is composed of an optical fiber core, tension members, an outer sheath, and so forth. The optical fiber core and the tension members are integrated by the outer sheath. The outer sheath is composed of a transparent material. The optical fiber core includes a glass wire and a resin coating (a primary resin layer and a secondary resin layer). The optical fiber core does not have a colored layer that is conventionally formed on the outer periphery of the resin coating layer. That is, the optical fiber core is composed entirely of transparent materials. On both sides of the optical fiber core, separate from the optical fiber core, is arranged a pair of tension members. The tension members are composed of transparent materials.

A polymer composite wireline cable comprising: a polymeric matrix material; at least one reinforced fiber embedded in the polymeric matrix material; and at least one optical fiber disposed in the polymeric matrix material, the at least one optical fiber having at least one pair of Bragg grating sensors, wherein one of the pair of Bragg grating sensors is configured to experience loading strain and the other of the pair of Bragg grating sensors is configured not to experience loading strain.

This application relates to a fibre optic cable structure suitable for use as a sensing fibre optic for distributed acoustic sensing and having an improved sensitivity to transverse pressure waves. The application describes a fibre optic cable (300) having a longitudinal cable axis and comprising at least one optical fibre (301). The cable also comprises a compliant core material (303) mechanically coupled to the optical fibre(s), possible via a buffer (302) such that a longitudinal force acting on the compliant core material induces a longitudinal strain in the optical fibre(s). At least one deformable strain transformer (304) is coupled to the compliant core material and configured such that a force acting on the strain transformer in a direction transverse to the cable axis results in a deformation of the strain transformer thereby applying a longitudinal force to the compliant core material.

Embodiments of the present invention address aliasing problems by providing a plurality of discrete acoustic sensors along a cable whereby acoustic signals may be measured in situations where the fiber optic cable has not been secured to a structure or area by a series of clamps, as described in the prior art. Acoustic sampling points are achieved by selectively enhancing the acoustic coupling between the outer layer and the at least one optical fiber arrangement, such that acoustic energy may be transmitted selectively from the outer layer to the at least one optical fiber arrangement. The resulting regions of acoustic coupling along the cable allow the optical fiber to detect acoustic signals. Regions between the outer layer and the at least one optical fiber arrangement that contain material which is acoustically insulating further this enhancement since acoustic waves are unable to travel through such mediums, or at least travel through such mediums at a reduced rate.

A cable adapter or connector for an ATEM camera converter includes a bracket secured to at least two holes on a bottom of the ATEM camera converter. Also included is at least a Neutrik opticalCON® fiber chassis connector secured to a cut-out in the bracket by at least two rivets. Two dual ST chassis connectors or dual FC chassis connectors are installed in the cut-out of the bracket using one or more wide nuts with one or more lock-washers. There is also one or more fiber optic cables that terminate with at least one of the Neutrik opticalCON® or dual ST or dual FC chassis connectors. The fiber optic cables terminated with either Neutrik opticalCON®, dual ST or dual FC connectors may be used with the camera converter.

A cable (10) includes a cable body (11) that is formed from a plurality of wires (14) that are integrally bundled; and a pair of sockets (12) to which both end portions of the cable body (11) is separately affixed; at least one of the plurality of wires (14) being a fiber-containing wire (16), which is formed by an optical fiber (17) that extends in a cable length direction (D) and that is protected by a protective tube (18); wherein the optical fiber (17) protrudes from the protective tube (18), in the cable length direction, further outside than the socket (12); and each of the pair of sockets (12) is provided with a spool (30) that removably holds the optical fiber (17) and imparts an initial tensile strain to the optical fiber (17).

A terminal connector or two-part connector comprising male and female parts having respective contact pins and contact receivers (10,15) of a construction generally known in the art. In the body (1) of the or at least one part, closely juxtaposed a terminal block (9), there is provided a conductor management device (8) adapted to receive conductors (12) as they are unbundled from the connected cable or reel and support the unbundled or individual conductors through the transitional region of the connector part to where they are secured at the terminal block (9). The conductor management device (8) has through body apertures defining each conductor path (14) to align each conductor with its respective receiver (13). In a different configuration, the conductor management device provides strain relief to the conductors, provides support and conductor rigidity, provides a locking means and is a bore modifier.
