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. The fiber carries data as pulses of light, and has nowadays overtaken copper wire as the medium of choice – primarily because it is lower cost, faster and less bulky. Optical fiber is also harder to hack than copper, making it more secure and safer because it doesn't generate heat. One such factor. Cold weather can affect fiber optic cables, but they are generally more resilient to temperature extremes compared to other types of cables, such as copper. Water can make its way into the conduit or duct carrying the fiber, typically if there are any gaps or imperfect joins at the connectors.
