                                According to the Fiber Optic Association, yellow identifies single-mode cable, while orange signifies older multimode cables, with aqua now used for newer multimode versions. Therefore, the fundamental difference between yellow fiber and orange fiber is the core size, which dictates the transmission distance and bandwidth capacity.
