During cabling, the multi-fiber cable needs to be branched before it is terminated. In order to meet the customer's pulling-eye and cabling demand, JFOPT has developed various waterproof pulling-eye kits, which can protect the branching part of FO patch cord from the damage caused by the impact or friction of any hard object. One of the various components is the PA corrugated tube. It can bear large tensile force and crush load, with flexibly bendable characteristics. The waterproof pulling-eye kit with PA tube can provide protection up to IP67 to meet the wiring requirements in harsh environment.
