HANSUN SFP stands for small form-factor pluggable, also know as mini-gbic (gigabit interface converter).
An SFP module is simply a small modular transceiver that plugs into an SFP port on a network switch or server. SFP module has replaced the GBIC module in most applications because of its small size, allowing it to be used in tight networking spaces to provide fast communication between switches and important networking components. And, SFP module is hot-pluggable, which makes it easy to adjust existing networks without having to redesign the entire cable infrastructure.
