Product Features
Technical Overview
This DAC cable operates at 100 Gbit/s using the 100GBASE-CR4 Ethernet standard, which divides the 100 Gb/s signal across four lanes of 25 Gb/s each over twinaxial copper. The QSFP28 form factor supports high-density port configurations, allowing for efficient use of rack space in modern data centers.
The passive electrical design eliminates active components, resulting in lower power consumption and reduced latency compared to active optical cables. The twinaxial construction provides excellent signal integrity over the 5-meter distance, maintaining stable performance without signal degradation.

FAQ
What is the maximum distance this DAC cable can reliably support?
This 100GBASE-CR4 QSFP28 passive DAC cable is designed for short-reach applications up to 5 meters (16.4 feet). The twinaxial copper construction maintains signal integrity within this distance without requiring signal regeneration or active components. For longer distances, active optical cables or fiber optic transceivers would be more appropriate.
Is this cable compatible with non-Arista networking equipment?
While specifically engineered and tested for Arista compatibility, this QSFP28 DAC cable uses standard 100GBASE-CR4 signaling and may work with other vendors' equipment that supports the same standard. However, for guaranteed performance, it's recommended to verify compatibility with your specific network device manufacturer before deployment.
What does 'passive' mean in the context of this DAC cable?
A passive DAC cable contains no active electronic components for signal processing or regeneration. It relies on the electrical properties of the copper conductors to transmit signals, resulting in lower power consumption, reduced latency, and simpler design compared to active cables. The passive design makes this cable more reliable with fewer potential points of failure.
Can this cable be used for 40GbE connections?
No, this cable is specifically designed for 100GbE (100 Gigabit Ethernet) connections using the 100GBASE-CR4 standard. While QSFP28 ports are backward compatible with some QSFP+ devices in certain configurations, this cable is optimized for 100GbE operation and should not be used for 40GbE applications, which require different signaling standards and cable specifications.
