Some connectors have a push-and-pull design, while others may require twisting or unlocking. One specific problem is how the fibers and connectors cope with sub-zero temperatures. 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. However, extreme cold, ice, or snow can affect the cable's outer jacket, cause physical stress, or.
