Arista CAB-Q-Q-100G-0.5-Arista | 100G QSFP28 Passive DAC Cable, 0.5m (2ft)

Q: What is the maximum distance supported by this DAC cable?
A: This passive direct attach copper cable supports connections up to 0.5 meters (approximately 1.64 feet), making it ideal for short-reach interconnects within a rack or between adjacent racks in data center environments.

Q: Is this cable compatible with non-Arista switches?
A: While this cable is designed for Arista Networks equipment and programmed with Arista compatibility codes, many third-party compatible versions support multi-vendor environments. Check with your vendor for cross-compatibility options or recoding services if connecting to other brands.

Q: What is the advantage of passive DAC over active DAC?
A: Passive DAC cables have no active signal amplification, resulting in lower power consumption (typically 0.5W vs 1-2W for active), lower cost, and lower latency. They are ideal for short-distance connections up to 5 meters.

Q: Can this cable be used for 40G connections?
A: No, this is a 100G QSFP28 cable designed specifically for 100 Gigabit Ethernet applications. For 40G connectivity, you would need a QSFP+ 40G DAC cable with the appropriate part number.

Q: What applications is this cable best suited for?
A: This cable is ideal for data center top-of-rack switching, server-to-switch connectivity, switch-to-switch interconnects within the same rack or adjacent racks, and any short-reach 100G application where cost efficiency and low power consumption are priorities.
