Connection method of cold joint of fiber optic connector
Emergency connection, also known as cold splicing, uses mechanical and chemical methods to fix and bond two fibers together. This method is quick and reliable, with typical attenuation ranging from 0. Active connection utilizes various fiber optic connectors (plugs and sockets) to connect site-to-site or site-to-cable. Unlike fiber splicing, which is permanent, connectors allow for easy connection and disconnection of cables, making them ideal for maintenance and flexibility in. Examples are fiber lasers and systems for optical fiber communications. There are different techniques for joining fiber ends: Permanent and stable connections with very low insertion losses can be obtained by fusion splicing.
