What is OM5 Multi Mode Fiber? Any different from OM1, OM2, OM3, OM4?

The optical communication  in the  "OM"  means  "Optical the Multi  -  MODE”,  light mode, multimode  fiber  represents standard fiber level. Currently,  TIA  and  IEC  defined fiber patch cord standards are  OM1,   OM2,   OM3, OM4  and  OM5. First of all, what is multimode and single-mode? Single-mode fiber (Single  Mode Fiber)  allow only one mode transmission fiber, the core diameter of about  8  ~  9 μm,  an outer diameter of about  125 μm.  Multimode fiber (Multimode  Optical Fiber)  allowing transmission of light in different modes of a single optical fiber, a core diameter of  50 μm  to  62.5μm.  Compared to single-mode fiber multimode fiber can support longer transmission distance, in  100Mbps  of  Ethernet  as well as  1G  Gigabit Ethernet single-mode fiber can support more than ...
