BlueOptics HPE R9F84A Compatible BlueLAN DAC SFP+ Direct Attach Cable - 0.5m Passive Twinaxial Copper 10GbE

The BlueOptics BlueLAN DAC SFP+ Direct Attach Cable is a high-performance, cost-effective solution for short-range 10 Gigabit Ethernet connections. Designed to be fully compatible with HPE R9F84A and other SFP+ 10GbE compliant devices, this passive twinaxial copper cable delivers reliable, low-latency data transmission for data center, server-to-switch, and storage area network (SAN) applications.

Advantages

This Direct Attach Cable (DAC) offers significant advantages over traditional optical transceivers and fiber optic cabling. It provides a lower total cost of ownership, reduced power consumption (less than 0.1W per end), and simplified cable management. The passive design ensures zero power draw from the host device, while the twinaxial copper construction guarantees excellent signal integrity over short distances. With hot-swappable SFP+ connectors on both ends, installation is quick and tool-free.

Suitable for

• Data center top-of-rack and end-of-row connectivity
• Server-to-switch links in enterprise networks
• Storage Area Network (SAN) and Network Attached Storage (NAS) connections
• High-performance computing clusters
• Any SFP+ 10GbE compliant device requiring short-range copper cabling
