Breakout cables are also called fanout cables. In tight buffered cables each fiber is only a 900um tight buffered fiber, but in breakout cables every fiber is a subcable by itself. Each fiber has a 2~3mm jacket, then outer jacket covers these subcables, aramid yarn and ripcord inside. This design allows users to divide the cable to serve users with individual fibers, without the need for patch panel. Breakout cable enables the quick installation of connectors onto 2+mm robust jacketed fiber.
