HPE R0R41B 

10GBASE‑T SFP+ Copper Transceiver module (RJ‑45, up to 30 m)

The HPE R0R41B is a 10 GbE SFP+ Transceiver module featuring an RJ‑45 connector for copper cabling up to 30 meters over Cat 6A/7. Ideal for short-distanceswitches or blade server interconnects requiring high-speed copper connectivity without fiber optics. It provides up to 10 Gbps full-duplex throughput with support for auto-negotiation across 1 Gb, 2.5 Gb, 5 Gb, and 10 Gb Ethernet speeds. Designed for seamless operation with HPE switches such as SN3700 and SN3000 series and compatible SFP+ ports, it offers hot-plug flexibility and optional Digital Optical Monitoring (DOM) for performance diagnostics. Suitable for dense rack deployments, service aggregation, or migrating from legacy copper networks to 10 GbE infrastructure.

Features

This copper SFP+ module enables 10 Gb Ethernet connectivity via standard RJ‑45 cabling, making it a cost-effective alternative to fiber in short-distance rack environments. It auto-negotiates multiple speeds for compatibility with both legacy and modern endpoints and supports extended functionality like link diagnostics via DOM. Compact and hot-swappable, the transceiver fits into standard SFP+ cages and works reliably in rugged operating temperature ranges. Integration is plug-and-play—no specialized driver required—and it's backward-compatible with existing Cat 6A cabling infrastructure. A compatible alternative model (R0R41B‑C) meets TAA certification and MSA interoperability standards, ensuring consistent performance across multi-vendor deployments.

Advanced Options

Engineered for reliability in enterprise rack environments, this module supports full 10 Gbps throughput at extremely low latency over copper media. With DOM support, administrators can monitor temperature, voltage, transmit/receive power,
