2024.07.09
SR, LR, LRM, ER and ZR are the more common module types in the 10GIEEE standard, but what is the difference between 10g SR, LR, LRM, ER and ZR? First we need to know what they represent. In fiber optic communication, SR, LR, LRM, ER and ZR are a kind of distance terminology in 10G optical module transmission, SR means short distance, LR means long distance, LRM means length extended multipoint mode, ER means ultra-long distance, and ZR means the longest distance.
