Our review focuses on compatibility, range and build: this SFP supports 1000Base-LX on single-mode fiber with LC connectors and lists support for several Aruba switch models, making it a sensible pick when replacing or expanding uplinks. It ships as a new retail hologram unit, which helps provide confidence in authenticity and packaging.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible models:\u003c\/strong\u003e Works with Aruba 2930M 24, 2930M 40, 2930M 48, 8320 and matching modules so it integrates cleanly into Aruba hardware fleets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong-range link:\u003c\/strong\u003e 1000Base-LX single-mode optics enable fiber spans up to about 6.2 miles for extended site-to-site connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLC single-mode connector:\u003c\/strong\u003e Uses common LC connectors for easy installation into existing fiber infrastructure without special adapters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eForm factor:\u003c\/strong\u003e SFP (mini-GBIC) physical size lets it occupy standard small-form ports on switches and modules, freeing slot space.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNew retail packaging:\u003c\/strong\u003e Supplied as new retail hologram units, which helps assure buyers of genuine parts and factory packaging.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis module is aimed at IT teams and installers managing Aruba switch deployments that require a gigabit fiber uplink over longer distances.
