Fiber optic connector when the contact front end development pin insertion appears to be stressed

Fiber optic connector when the front end of the contact piece to develop the pin plug end face bear backward working pressure, flange relative to the subject of the activity set backward fitness movement, installed in the flange and the subject of the activity set on the elastic yellow is narrowed, the elasticity caused by the working pressure with the pin plug end face phase state, RF connector connection the elasticity that is the fiber optic line end face between the completion of the physics of the contact end face working pressure. The compressive strength of the contact piece of the structure of the fiber optic cable in the tensile components (generally aramid) and fiber optic cable skin immobilized at the end of the contact piece, when immobilized at the end of the flange, the contact piece in the assumption of tensile force, the flange and the needle plug will be with the fiber optic cable back; when immobilized in the subject of the activities of the sleeve tail, the contact piece in the assumption of tensile force, the flange and the needle plug is not easy to back up with the fiber optic cable. After a long period of statistical analysis shows information, the failure mode of fiber optic connector contains fiber optic line breakage, bonding ineffective, fiber optic line bulge and concave, fiber optic line end face environmental pollution, fiber optic line end face damage and ceramic parts crushed, fiber optic cable crack, liquid body penetration and so on. Among them, the previous types of ineffectiveness are more prevalent and have great harm. The following analysis of this typical failure mode. Fiber optic cable breakage fiber optic cable breakage will cause optical transmission data signal output power is more serious reduction, or even signal interruption, is essential to minimize the generation of more serious common failures. Fiber optic cable breakage according to the different parts of the break can be divided into the outside world of the radio frequency connector, the end of the contact and the internal contact.
