Not-Too-Tight Mating of Fiber Optic Connectors



Another tip for good fiber connector mating is: not too tight. Unlike electrical connections, tighter is not better.


The connector’s job is to bring the endfaces of two fibers together. Once they touch, tighter only causes a greater force to be applied to the delicate endface. In some connectors, the end can cock off-axis with a tight connection (due to the curved face) resulting in a worse return loss.

Many measurements are actually improved by backing off the connector pressure. Also, if a piece of grit does happen to get by the cleaning procedure, a tighter connection is more likely to damage the glass. Tighten just until the two fibers touch.
