Arista CAB-S-S-25G-2M | 25G SFP28 DAC Twinax Cable, Passive, 2m, 10G/25G Dual-Rate

Q: What switches is the CAB-S-S-25G-2M compatible with?
A: This cable is designed for use with Arista EOS-based switches and routers equipped with SFP28 ports, including the Arista 7050CX3, 7060CX2, 7170, and other 25G-capable platforms. It is natively recognised by EOS without requiring third-party qualification.

Q: Can this cable operate at 10G, or is it 25G only?
A: The CAB-S-S-25G-2M supports dual-rate operation at both 10Gbps and 25Gbps, making it suitable for environments that include a mix of 10G and 25G infrastructure.

Q: Is this an active or passive cable?
A: This is a passive direct attach copper (DAC) twinax cable. It contains no active electronic components, resulting in lower power consumption (max 0.57W per end) and simpler deployment compared to active optical cable alternatives.

Q: What is the maximum reach of this DAC cable?
A: The CAB-S-S-25G-2M has a fixed cable length of 2 metres (6.6 ft), making it suited for intra-rack connections or short rack-to-rack links in high-density data centre environments.
