How many cores can a multimode fiber optic module use
Single-mode fiber uses a 9/125 µm core/cladding structure that supports only one propagation mode, which minimizes modal dispersion and allows signals to travel tens of kilometers with low attenuation. Because of this, more data can pass through the multimode fiber core at a given time. With multiple multimode fiber types available— OM1, OM2, OM3, OM4, and OM5 —choosing the right fiber for your network can be challenging. The number of optical cores in an optical fiber is the total number of equipment interfaces multiplied by 2, plus 10% to 20% of the spare quantity, and if the communication mode of the equipment has serial communication and equipment multiplexing, you can reduce the number of cores.
