## Long description

The Direct Attach Cable HPE R9F84A SFP+ to SFP+ 10G Twinax Copper 1m Black is a passive SFP+ twinax cable designed for short-distance, high-speed 10 Gigabit connections between SFP+ ports. With a 1 meter length and a compact form factor, the cable provides low latency and high signal integrity for top-of-rack and adjacent-rack links in data centers and enterprise networks. Its black jacket and robust connector assemblies suit constrained rack environments where reliable, cost-effective copper interconnects are required.
Advantages
This 10G Twinax copper cable delivers stable throughput with minimal power consumption compared with active optical transceivers, offering a practical option for short-reach links. The passive design reduces complexity and heat generation in network equipment. Its fixed 1 m length simplifies cabling in dense rack layouts and helps maintain predictable signal performance. The cable's shielded twinax construction ensures consistent transmission and resistance to crosstalk in crowded cable runs.
Suitable for
 Connecting SFP+ ports between switches, servers, and storage in the same rack
 Short inter-rack links in adjacent racks within data centers
 High-throughput, low-latency connections for virtualization and SAN environments
 Upgrading or consolidating 10 Gigabit network segments where fiber is not required
Key specifications
 Interface: SFP+ to SFP+ (10Gb/s)
 Medium: Twinax copper
 Length: 1 meter
 Type: Passive direct attach cable
 Color: Black
 Use case: Short-reach, rack and adjacent-rack connections
How to use
Install the cable by inserting each SFP+ connector into the corresponding SFP+ port on network switches, servers or storage appliances until the latch clicks. Ensure both ends are fully seated and that equipment ports are powered down or handle hot-plugging according to the device manufacturer's guidance. Route the cable to avoid sharp bends and excessive strain; maintain the 1 m routing for optimal signal performance. Verify link lights and network settings to confirm a stable 10 Gb/s connection.
Usage recommendations
For reliable operation, use this passive SFP+ twinax cable for short-reach connections within the same rack or between adjacent racks. Avoid routing near high-power cables and maintain bend radii recommended for twinax cabling. When integrating with network equipment, consult compatibility lists for SFP+ ports and follow vendor guidance for hot-plug handling to preserve connector and port integrity.
