Optical fiber cold splice technology is based on the use of mechanical connectors to join two fiber-optic cables. Unlike fiber splicing, which is permanent, connectors allow for easy connection and disconnection of cables, making them ideal for maintenance and flexibility in. When deploying fiber optic cabling, one of the most critical decisions is how to terminate the fiber—either by splicing or using connectors. It uses pre-installed index-matching gel or mechanical clamping to align the bare fiber with a short fiber stub inside. Where copper twisted pairs tend to terminate with an RJ45 plug, fiber optic connectors come in all sorts of shapes and sizes, with all manner of different use cases in mind.
