Zyxel SFP-SX-D network transceiver module 1000 Mbit/s 850 nm

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 dont 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.<br />- Gigabit Performance Transmission and Flexibility<br />- Small Size and High Port Density<br />- Industry Standard-based Compliance<br /><br /><b>Gigabit Speed and Flexibility</b><br />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.<br /> <br /><b>Small Size and High Port Density</b><br />ZyXEL's SFP transceiver's compact design provides high port density.
