BlueLAN 747522301-BL cavo direct attach passivo 10GBASE-CR SFP+ a SFP+, 3m, AWG30

Direct attach cable with SFP+ connectors on both ends, delivering 10 Gbps over twinax copper for short-reach data center links. The passive design consumes under 0.1W, making it an efficient choice for high-density rack-to-rack and server-to-switch interconnects.

Advantages

Passive twinax construction eliminates optical transceivers, reducing cost and latency while maintaining signal integrity over 3 meters. AWG30 wire gauge balances flexibility with performance, and the 100 Ohm impedance ensures reliable 10GBASE-CR Ethernet operation. Hot-swappable connectors simplify installation and maintenance.

Suitable for

• Data center top-of-rack to end-of-row connections
• Server to access switch uplinks
• Storage and compute clusters requiring low-latency 10G links
