Principle of Bolivia Multimode Logging Optical Cable
Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. ApplicationsThe equipment used for communications over multi-mode optical fiber is less expensive than that for.
