ST Fiber Optic Connector

ST Splice-On Connector

The weak point of other fusion splice-on connectors occurs when the shock absorber of the stop ring is sleeved by heat shrink after fusion splicing. Typically, if the ferrule fiber, primary fiber, and the ferrule take a load toward the primary fiber, the fiber can be bent as shown in the diagrams below – possibly causing a disconnection of the fiber. To resolve this problem, the UCL Swift fiber optic splice-on connectors, such as the ST Splice-On Connector, uses the ferrule to disperse this transformation and prevent fiber optic disconnect.
