There are currently many models of SFP+ optical modules on the market, such as SFP-10G-SR optical modules for multi-mode transmission, SFP-10G-LR optical modules for single-mode transmission, and SFP-10G-LR optical modules that can be used for both single-mode transmission and SFP-10G-LRM optical module for multi-mode transmission. So what is the difference between SFP-10G-LRM optical module and SFP-10G-SR optical module? And what is the difference between SFP-10G-LRM optical module and SFP-10G-

What is SFP? The Small Form-factor Pluggable (SFP) is a compact, hot-swappable transceiver used in data and telecommunications networks. Its primary purpose is to provide a flexible way to connect various network devices, such as switches, routers, and media converters, to fiber optic or copper cabling. Designed to fit into a special SFP port on networking devices, it facilitates seamless data transmission over short and long distances, depending on the module type.
