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. Active connection utilizes various fiber optic connectors (plugs and sockets) to connect site-to-site or site-to-cable. This method is flexible, simple, convenient, and reliable, commonly used in building computer network cabling. The typical attenuation is 1dB per connection. During installation, all curvatures should be smooth.
