The main differences between MPO single-mode fiber and multimode fiber are transmission distance, intermodal dispersion and fiber type. 1
Transmission distance: Single-mode fiber (SM) is usually used for long-distance transmission because of its small intermodal dispersion, which is suitable for long-distance communication. Multimode fiber (MM) is suitable for short-distance transmission, with large intermodal dispersion. As the transmission distance increases, the signal quality will decrease.
Intermodal dispersion: Single-mode fiber has small intermodal dispersion and is suitable for long-distance transmission. Multimode fiber has large intermodal dispersion, and as the transmission distance increases, the signal quality will be affected.
Fiber type: The standards for single-mode fiber include ITU-T's G.652 to G.657, of which G.652 is the most common fiber type. Multimode fiber can be divided into OM1/OM2, OM3/OM4 and OM5 patch cords.
When choosing an MPO fiber patch cord, you need to decide whether to use single-mode or multimode fiber patch cords based on the actual transmission distance and network requirements of the application.
