Mechanical splicing is a method used to join two optical fibers together without the need for fusion splicing. This technique involves aligning the fibers precisely and using a mechanical device to hold them in place. The connection is typically made using a special alignment fixture and a protective housing to ensure stability and minimize signal loss. The advantages of mechanical splicing include its simplicity and speed, as it does not require specialized equipment like a fusion splicer. It is often used in situations where quick repairs or temporary connections are needed, making it a practical choice for telecommunications and fiber optic installations.
