Your switch has the SFP+ slot. Your cable run is copper. You need ten gigabits to cross that gap without pulling new fibre through the wall. The TL-SM5310-T drops into that slot and talks 10G over the Cat6a you already have, up to 30 metres. No re-patching. No fibre crew. Plug it in, set your speed, done. It handles 1G, 2.5G, 5G, and 10G on the same copper run, so one module covers your whole office floor. The metallic shell keeps EMI out of your signal, and DDM lets you watch temperature and voltage from your management console before a port starts dropping frames
