N61WR Dell SFP+ 10GBASE-T 30M Reach on CAT6A/7 Transceiver

N61WR Overview

The Dell  is a robust, SFP+ copper transceiver delivering 10GBASE‑T performance up to 30 m over Cat6a or Cat7 cabling, while also supporting fallback rates of 5G/2.5G/1G/100M BASE‑T over Cat5e. Ideal for high-density rack environments, server uplinks, and short fabric runs, the module fits seamlessly into Dell SFP+ cages and auto-negotiates speeds while supporting MDI/MDIX reversal.Although it draws more power and generates more heat than fiber optics, its low latency, cost-efficiency, and use of existing copper infrastructure make it a compelling choice. Just be aware of potential power/thermal limitations on some switches—performance can vary depending on the switch’s ability to power copper
