In fiber optic communication, a multimode fiber optical cable is usually used for short distance data transmission. Typical multimode fiber optic cables are 62.5/125 and 50/125 type. MMF stands for multimode fiber cable. Multimode fiber cable used indoor including the multimode fiber cable used to make patch cables are usually with 1.8mm, 2mm or 3mm outer diameter.
Fiber optics also known as "optical fiber" refers to the technology associated with information being transferred or transmitted as light impulses through fiber. Optical fiber cables carry more information than conventional copper wires and is far less subjected to electromagnetic interference.
