One or more spacers for installing an optical cable are disposed in a trench that extends along an axis. The optical cable includes one or more optical sensors. Each spacer includes a base configured to rest in a bottom of the trench. A first arm extends from the base. The first arm is adjacent to a first wall of the trench. An opposing second arm extends from the base. The second arm is adjacent to an opposing second wall of the trench. The optical cable is configured to extend along the axis.

A optical cable member includes an optical cable, a fixing member, a first housing tube, and a second housing tube. The optical cable includes an optical fiber and a tensile strength member. In the optical cable, a cable main body housing the optical fiber and the tensile strength member, and a cable exposure portion in which the optical fiber and the tensile strength member are exposed to an outside are provided. The fixing member fixes the tensile strength member. The first housing tube is disposed between the fixing member and the cable main body, houses the tensile strength member therein, and allows the optical fiber to extend therein. The second housing tube is disposed on a side opposite to the first housing tube of the fixing member, and houses the optical fiber of the cable exposure portion therein. The second housing tube is a bendable member.

A subsea data collection and communication system is installed at a subsea interconnect point or subsea connector used for communication between subsea electrical, optical or hybrid electro-optical cables. The data collection and communication system is configured to collect system performance data such as voltage, current, optical pressure and the like from signals carried by the wires or fibers in cables connected to the connector unit, and may also collect data on environmental conditions from sensors installed in or on the connector unit, such as temperature, pressure, or sea water salinity sensors, and the like. The collected data is transmitted to a remote monitoring station or local hub for further processing to detect potential faults or performance degradation either at periodic intervals or on demand, using bi-directional Ethernet, CANBUS, a carrier frequency system over the cable power lines, optical signal over optical fiber, or wireless communication links over short distances.

The present disclosure relates to a connector device for optical fiber configured to allow the transmission of an optical signal at a terminal end of the fiber in a cabling condition. The device comprises a portion of optical fiber having a ferrule at at least one terminal end, a ferrule holder element and a protective element for the optical fiber. The overall configuration is such that the connector device has small radial and longitudinal dimensions which, in an operating condition, allow rapid movement within wiring cables or tubular ducts, for example cable ducts, pipes, conduits etc., which due to their sizes, hinder the passage of standard connectors of known type.

Several methods of deploying an optical fiber carrying structure along a road are provided. In one method a recess and channel are created within a road. The optical fiber carrying structure is deployed in the channel and a cover encloses the optical fiber carrying structure within the channel. In another method the optical fiber carrying structure is anchored to the road and/or curb. In another method the optical fiber carrying structure is coupled to a brace that is affixed to the road. The brace facilitates quickly installing lateral transitions from the primary channel in the road to installation environments off the road.

The pipe cable ring clamp (1) comprising a coiled flat clip band (11) provided with transverse slots (111) on which at least one cable holder (4) is attached and comprising the outer coil (112) and the inner coil (113), and a strap lock (12) in which the clip band (11) is fastened, wherein the inner coil (113) of the clip band (11) is slidably mounted in the strap lock (12) and the strap lock (12) includes lock springs (139) coupled to the inner coil (113) of the clip band (11). The lock springs (139) are received in the strap lock (12) along the edges of the clip band (11) outside the contour of its perpendicular projection into the cylindrical surface of the pipe (5), the lock springs (139) are via the inner coil (113) of the clip band (11) coupled by the movable member (127) slidably mounted in the strap lock (12), wherein the movable member (127), on its end opposite to the rear wall (125) of the strap lock (12) is provided with spring stops (129) on which the lock springs (139) rest with one end thereof, while the other ends rest on the rear wall (125) of the strap lock (12) and wherein the movable member (127) is coupled to the inner coil (113) of the clip band (11) by a pusher tongue (133) in the pivotally mounted movable member (127), wherein the movable member (127) is adapted both to fix it in the rear position while compressing the lock springs (139) and to release it using the latch (135) slidably mounted in a vertical direction in the body of the movable member (127). It is also the basis of the series of pipe cable ring clamp installation apparatus invention.

Universal cable installation tools and methods for using the tools. A cable installation tool includes a cable fastening end and an opposite projecting end extending from fastening end. A cable can be temporarily fastened to the cable installation tool using the universal cable fastening end, allowing the cable installation tool and the operably coupled cable to be threaded through a wall opening.
