There is an optical cable inside the steel wire
Several different styles of OPGW are made. In one type, between 8 and 48 glass optical fibers are placed in a plastic tube. The tube is inserted into a stainless steel, aluminum, or aluminum-coated steel tube, with some slack length of fiber allowed to prevent strain on the glass fibers. The buffer tubes are filled with grease to protect the fiber unit from water and to protect the steel tube from corrosion; the interstices of the cable are filled with grease. The tube is stranded into the cable with aluminum, alumi.

The function of heat shrink tubing for steel wire fiber optic splicing
The heat shrink tube is slid over the connector or splice, and then it is heated to shrink the tube tightly around the connector or splice. This creates a strong, protective seal that prevents moisture, dust, and other contaminants from entering the connector or splice. This specialized tubing is designed to protect and secure optical fibers, providing a durable and reliable layer that can withstand the harsh environments commonly encountered in telecommunications. This product shrinks when heated and is used to repair broken. The product consists of a reinforced 304 stainless steel rod or a ceramic rod, a hot fusion tube and a cross-linked polyolefin tubing. A specially designed cross-linked. Single holed (preshrunk) ends eliminates improper fiber threading. Clear sleeve design permits easy centering.
