Can fiber optic cold splices break

A fiber splice is the permanent connection of two optical fibers. Once the two optical fibers are joined with a splice, they cannot be taken apart and put back together, as they can if you join them using connectors. The performance of a fiber optic splice is determined by a number of factors, including the quality of the fiber, the cleanliness of the splice, and the techniques used to make the splice. For protection against the outside plant environment and damage, splices require placement in a protective enclosure, usually called a splice closure. Splices are generally placed in a splice tray which is then placed inside a splice closure or. Broken a few fibers just trying to break out a buffer tube I never have to splice in the cold. 90% of the time I'm in the lab with the heat on or if the rig can't make it to the splice location we bring a tent heater and a UTV.
