Arista CAB-Q-Q-100G-5M-Arista | 100G QSFP28 Passive DAC Cable, 5m Twinax, 26AWG

Q: What is the maximum transmission distance for this cable?
A: The CAB-Q-Q-100G-5M is a 5-meter passive copper cable designed for short-reach interconnects within racks and across adjacent racks. It is not suitable for long-distance transmission; for distances beyond 5 meters, consider active copper cables or optical transceivers.

Q: Is this cable compatible with Arista switches and routers?
A: Yes, this cable is specifically designed and encoded to be compatible with Arista networking equipment, including modular spline switches, data centre switches, and campus PoE switches. It has been tested for compatibility with a wide range of Arista platforms.

Q: What is the difference between passive and active DAC cables?
A: Passive DAC cables like the CAB-Q-Q-100G-5M have no signal amplification, making them more cost-effective and power-efficient for shorter distances (typically up to 5 meters). Active DAC cables include signal amplification for longer distances but consume more power.

Q: Can this cable be used for 100G Ethernet applications?
A: Yes, the CAB-Q-Q-100G-5M supports 100G Ethernet (100GBASE-CR4) at 103.125 Gbps, as well as OTU4 at 112 Gbps. It is compliant with IEEE 802.3bj and 802.3ba standards for 100 Gigabit Ethernet.

Q: Does this cable support hot-plugging?
A: Yes, the CAB-Q-Q-100G-5M is hot-pluggable, allowing you to connect or disconnect the cable without powering down the equipment, which enhances uptime and simplifies serviceability.
