BlueOptics HPE R4G18A compatible BlueLAN 25GBASE-CR SFP28 a SFP28 Direct Attach pasivo, 0,5 m, 30 AWG

The BlueOptics BlueLAN R4G18A-BL is a high-performance, passive Direct Attach Copper (DAC) cable designed for 25 Gigabit Ethernet connectivity. It is fully compatible with HPE R4G18A transceivers and provides a cost-effective, low-power solution for short-range interconnects in data centers and enterprise networks.

Advantages

This cable offers reliable 25 Gbps data transmission over a 0.5-meter length, with ultra-low power consumption of less than 0.1W. The passive design ensures zero latency and no signal processing, making it ideal for high-density environments. Its 30 AWG twinax construction is flexible and durable, while the SFP28 connectors are hot-swappable for easy installation and maintenance.

Suitable for

• Data center server-to-switch connections
• Switch-to-switch interconnects
• High-performance computing clusters
• 25GBASE-CR compliant networks
