Arista CAB-S-S-25G-1M-Arista | 25G SFP28 Passive DAC Cable, 1m, Twinax Copper

Q: What is the CAB-S-S-25G-1M used for?
A: The CAB-S-S-25G-1M is a 25G passive DAC cable used for short-reach, high-speed connections between network switches, servers, and storage devices within racks or across adjacent racks in data centers. It provides a cost-effective alternative to optical transceivers for distances up to 1 meter.

Q: Is this cable compatible with 10G Ethernet equipment?
A: Yes, the CAB-S-S-25G-1M supports dual-rate operation and can be used with 10G Ethernet equipment. Arista's 25G twinax copper cables are designed to support both 10G and 25G data rates, providing backward compatibility with 10G SFP+ ports.

Q: Does this cable require external power or cooling?
A: No, the CAB-S-S-25G-1M is a passive copper cable that does not require external power or active cooling. It draws minimal power (max 0.57W per end) from the host equipment, making it an energy-efficient and low-maintenance connectivity solution.

Q: What switches and platforms support this cable?
A: This cable is designed for use with Arista switches and network adapters that feature 25G SFP28 ports. It is fully compatible with Arista's 25G-capable platforms and interoperates with industry-standard 25G SFP28 equipment that meets MSA specifications.

Q: Can I use this cable in high-density environments?
A: Yes, the compact SFP28 form factor and 1-meter length make this cable ideal for high-density rack environments. Its passive copper design reduces heat output and power consumption compared to active cables, making it suitable for densely populated switch deployments.
