Optical cables are manufactured to meet optical, mechanical, or environmental performance specifications
Jul 03, 2018

Optical cables are manufactured to meet optical, mechanical, or environmental performance specifications, using one or more optical fibers placed in a sheath to serve as a transmission medium, a communication cable assembly for use individually or in groups. The optical cable is generally composed of a cable core, a reinforcing steel wire, a filler and a sheath, and a waterproof layer, a buffer layer, an insulated metal wire and the like as needed. During the long-term use of the optical cable, due to the infiltration of moisture and moisture, the transmission performance of the optical cable will be deteriorated or even impossible to use. In the preparation process of communication optical cable, people pay great attention to the waterproof method and waterproof material of optical fiber cable. In order to prevent the intrusion of moisture and damage the fiber during the process of fabricating the cable, it is necessary to fill the cable gap in the cable gap and apply the filling compound on the fiber to ensure good mechanical properties and long service life. The ointment filled in the fiber loose tube, commonly referred to as fiber ointment, is one of the materials that have the greatest impact on fiber performance in layered and center tubular communication cables. It is generally believed that the optical fiber filling compound has two protection functions for preventing moisture intrusion and mechanical buffering. The cable with metal tape armor consists of a cable core and appropriate water-blocking measures, a double-sided coated steel/aluminum tape and a polyethylene sheath. The longitudinal water-blocking and moisture-proof structure of the cable consists of two parts. One part is the cable core blocking water, and the other part is the steel strip or the aluminum strip overlapping the partial water blocking. When the optical cable has steel/aluminum tape armoring, in order to improve the water blocking performance of the optical cable, a layer of hot melted solid glue or water-swellable water-blocking grease is continuously applied to the joint.
