SFP ports mean flexibility. The flexibility to choose which fiber you want to run and what sort of distance you need. They save money by allowing you to use existing fiber so you don?t have to run more. Instead of buying a switch with built-in fiber ports, buy a switch with SFP ports that allows you to choose what type of fiber transceiver you want to use on a port-by-port basis. - Gigabit Performance Transmission and Flexibility - Small Size and High Port Density - Industry Standard-based Compliance
Gigabit Speed and Flexibility ZyXEL's Small Form-factor Pluggable (SFP) transceiver family provides performance and flexibility with full duplex Gigabit speeds and hot-pluggable into Gigabit Ethernet port.
Small Size and High Port Density ZyXEL's SFP transceiver's compact design provides high port density. For example, ZyXEL GS-3012F switch can connect up to 12 fiber links - all at an affordable price.
Industry Standards-based Compliance ZyXEL's SFP transceiver family is compliant with IEEE 802.3z and SFP MSA allowing easy interoperability with all standard compliance devices from different vendors.
