Description

The Arista CAB-D-8S-200G-2M is a passive 200GBASE-CR8 Direct Attach Copper (DAC) breakout cable designed for high-density data centre connectivity. It features a single QSFP-DD connector on the host end and eight 25GBASE-CR SFP connectors on the device end, enabling a 200G port to fan out across eight 25G server NICs or legacy SFP devices. With eight 25G NRZ electrical lanes, no active components, and zero additional power draw, this cable is the cost-effective choice for top-of-rack server connectivity on Arista platforms running EOS 4.23.0 or later.

Fully certified on all supported Arista switches and integrated with EOS and CloudVision, this cable is plug-and-play and hot-swappable. It is EEPROM-programmed for up to 25G NRZ data rates, ensuring broad compatibility with legacy 100G QSFP and 25G SFP infrastructure. Part of Arista's comprehensive 1G to 400G cable portfolio, the CAB-D-8S-200G-2M is available in 1m, 2m, 2.5m and 3m variants.

FAQs

Q: What does the CAB-D-8S-200G-2M connect?
A: It connects a single QSFP-DD port configured for 200G (8 x 25G NRZ lanes) on an Arista switch to eight separate 25GBASE-CR SFP ports on servers or other 25G-capable devices — a common top-of-rack breakout configuration in data centres.

Q: Does this cable require any active components or additional power?
A: No. The CAB-D-8S-200G-2M is a fully passive DAC cable with no active electronics. It draws no additional power from the switch, making it one of the most energy-efficient connectivity options available.

Q: Which Arista EOS version is required for this cable?
A: A minimum of Arista EOS version 4.23.0 is required. The cable is certified on all supported Arista platforms and integrates seamlessly with EOS and CloudVision for plug-and-play deployment.

Q: Is this cable compatible with non-Arista 25G SFP equipment?
A: The cable is EEPROM-programmed for 25G NRZ data rates, providing broad compatibility with legacy 25G SFP NICs and switches. However, Arista certifies and provides full support only for use on supported Arista platforms.

Q: What other lengths are available in this cable family?
A: The same 200G QSFP-DD to 8x 25G SFP passive DAC breakout family is available in 1m, 2m, 2.5m, and 3m lengths, allowing you to choose the right reach for your rack layout.

Q: Can I purchase the Arista CAB-D-8S-200G-2M in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian B2B IT hardware reseller stocking Arista transceivers and DAC cables. Contact our team for pricing, availability, and volume orders with expert pre-sales support.
