Most modern network devices that support SFP slots and LC connectors work with this module.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >What fiber type does SFP-1G-EZX need?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You need <strong>single-mode fiber (SMF)<\/strong> for SFP-1G-EZX. This type of fiber lets you send data over long distances. Multi-mode fiber will not work with this module.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >What should you do if SFP-1G-EZX does not work?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">First, check your connections and make sure the module fits tightly. Clean the fiber ends. Make sure your device supports SFP-1G-EZX. Try the module in another port if you still have problems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >What is the maximum distance for SFP-1G-EZX?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">SFP-1G-EZX can send data up to 100 kilometers. This makes it a good choice for long-distance links between buildings, campuses, or cities.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" >What makes SFP-1G-EZX different from other SFP modules?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">SFP-1G-EZX supports longer distances than most standard SFP modules. It uses a 1550 nm wavelength and works with single-mode fiber. You get reliable, high-speed data over much greater distances.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"<p>What is sfp-1g-ezx?
