Description
The Cudy SFP+ to 10G RJ45 Module is a hot-pluggable SFP+ copper transceiver that converts an SFP+ port into a 10GBASE-T RJ45 port. It supports up to 10 Gbps over copper, falls back to lower link speeds (5G/2.5G/1G) when required, and is intended for short-to-moderate distance 10G copper links using high-quality cabling. Ideal for adding 10G copper to switches, routers, NICs or servers without replacing the host hardware or wiring infrastructure.
Tech Specs
| Connector | RJ45 (10GBASE-T) |
| Data Rate | 10 Gbps (supports negotiation to 5G / 2.5G / 1G) |
| Form Factor | SFP+ (hot-pluggable) |
| Mode | Copper (10G-T) |
| Recommended Cable | Cat6a or better (Cat7 recommended for best margin at 10G) |
| Typical Distance | Short-to-moderate spans — many modules are specified for tens of metres at full 10G; distance depends on cable quality and environment. |
| Power | Powered from SFP+ slot: +3.3 V nominal; typical current ≈ 800 mA (peaks up to ~1 A) — verify host port power budget. |
| Thermals | Runs warmer than fiber SFP+ modules; can become hot under sustained 10G load — ensure airflow/ventilation around module ports. |
| Compatibility Notes | Host devices vary — some switches/NICs accept copper SFP+ modules natively, others require a vendor-supported transceiver or an “unsupported transceiver” option in firmware. Verify compatibility with your switch/router/NIC vendor. |
| Use Cases | Add 10G copper to existing SFP+ ports, connect 10G NAS/servers over copper, short rack-to-rack links without fiber, or enable mixed fiber/copper deployments. |
| Warranty Terms: | 1-Year Warranty provided by 101 Multimedia |
