BlueOptics Lenovo A51N Compatible BlueLAN 10GBASE-CR Passive SFP+ Direct Attach Cable, 2 Meter, AWG30

The BlueOptics A51N-BL is a high-performance, passive Direct Attach Cable (DAC) designed for 10 Gigabit Ethernet connectivity. This SFP+ to SFP+ twinax copper cable is fully compatible with Lenovo A51N and other standard SFP+ ports, offering a cost-effective and reliable solution for short-range interconnects in data centers and enterprise networks.

Advantages

This passive DAC cable delivers low power consumption (<0.1W) and zero latency, making it ideal for high-density environments. Its pre-terminated design eliminates the need for separate transceivers, reducing cost and complexity. The AWG30 wire gauge ensures flexibility for easy cable management, while the 2-meter length is perfect for rack-to-rack or server-to-switch connections.

Suitable for

• Data center interconnect (top-of-rack to server)
• High-performance computing (HPC) clusters
• Enterprise networking (Cisco, Juniper, Arista, Mellanox, HP, Dell, IBM, Lenovo)
• Server-to-switch and switch-to-switch links
