Fiber optic cold connection, also known as mechanical splicing, is a widely used method of connecting optical fibers in a network. Unlike fusion splicing, which uses heat to join two optical fibers together, cold connection uses mechanical means to create a stable and low-loss. A fiber optic connector is a mechanical device used to align and join optical fibers, enabling light to pass through with minimal loss. This method is flexible, simple, convenient, and reliable, commonly used in building computer network cabling. The typical attenuation is 1dB per connection. It uses pre-installed index-matching gel or mechanical clamping to align the bare fiber with a short fiber stub inside. Optical fiber active connectors, commonly known as live joints, generally called optical fiber connectors, are reusable passive devices used to connect two optical fibers or optical cables to form a continuous optical path.
