This refurbished 4-port SFP+ module is presented as a used but professionally inspected unit, making it appealing for labs, branch office upgrades, or IT teams replacing a failed port module without paying for new retail hardware. The single biggest reason to buy is the combination of Cisco hardware compatibility and a verified working condition that restores 10GbE uplink capacity quickly.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour 10GbE SFP+ ports:\u003c\/strong\u003e Provides four high-speed SFP+ ports to expand uplink or server connectivity on supported Catalyst switches.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCisco system compatibility:\u003c\/strong\u003e Designed for Cisco Catalyst platforms, helping ensure predictable behavior in existing Cisco network environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewed and tested:\u003c\/strong\u003e The module is pre-owned but professionally inspected and tested to work and look like new, reducing risk versus unknown used units.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact expansion form:\u003c\/strong\u003e Small module size lets administrators add 10GbE density without replacing the whole chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDevice-only delivery:\u003c\/strong\u003e Included unit is ready for installation where available SFP+ transceivers and cables are already on hand.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis module suits IT professionals, small data centers, and managed service providers who operate Catalyst switch families and need to add or replace 10GbE SFP+ ports without the expense of a new OEM module.
