Description

The Arista CAB-D-4Q-200-2.5 is a 200GBASE-CR8 passive twinax copper DAC breakout cable designed for high-density data centre interconnects. It splits a single QSFP-DD port (200G via 8x25G NRZ lanes) into four 50GBASE-CR2 QSFP ports, enabling top-of-rack and rack-to-rack cabling at 2.5 metres with minimal latency and power overhead. Ideal for connecting spine-and-leaf architectures, servers, and storage nodes where short-reach, high-bandwidth connectivity is critical.

As a passive twinax copper cable, it requires no additional power, drivers, or software configuration beyond Arista EOS 4.23.0 or later. The plug-and-play, hot-swappable design simplifies deployment and maintenance, while MSA-compliant construction supports interoperability with legacy 100G QSFP and 25G SFP environments.

Features

- Passive twinax copper design delivers ultra-low latency and minimal power consumption
- Breakout functionality: one 200G QSFP-DD port splits into four independent 50G QSFP connections
- Supports interoperability with legacy 100G QSFP and 25G SFP infrastructure
- Plug-and-play installation — no drivers, firmware, or additional software required
- Hot-swappable for seamless maintenance and upgrades in live environments
- MSA-compliant construction for broad multi-vendor interoperability
- Optimised for high-density data centre spine-leaf, top-of-rack, and server interconnect deployments
- Supported on Arista EOS 4.23.0 and later — consult Arista Transceiver and Cable Guide for platform-specific compatibility

FAQs

Q: What does the CAB-D-4Q-200-2.5 connect?
A: It connects a single 200GBASE-CR8 QSFP-DD port to four 50GBASE-CR2 QSFP ports, breaking out 200G of aggregate bandwidth into four independent 50G links using 8x25G NRZ electrical lanes.

Q: Is this cable compatible with non-Arista equipment?
A: The cable is MSA-compliant, meaning it supports interoperability with legacy 100G QSFP and 25G SFP ports. However, full functionality and platform support are guaranteed on Arista EOS 4.23.0 and later — always consult the Arista Transceiver and Cable Guide for your specific platform.

Q: Does the QSFP-DD port need special configuration?
A: Yes. The QSFP-DD host-side port must be explicitly configured for 200G mode in Arista EOS. No additional drivers or software are required beyond standard EOS 4.23.0 or later.

Q: Is this a passive or active cable, and why does it matter?
A: This is a passive twinax copper DAC cable, meaning it draws negligible power and introduces very low latency compared to active optical cables. It is ideal for short-reach intra-rack and top-of-rack deployments up to 2.5 metres.

Q: Can I hot-swap this cable without taking the switch offline?
A: Yes. The CAB-D-4Q-200-2.5 is hot-swappable, allowing you to install or replace it without powering down the switch or server, simplifying maintenance in live data centre environments.

Q: Can I purchase this cable in Australia through IP Trading?
A: Yes. IP Trading stocks Arista cables and optics and ships across Australia. Visit iptrading.com.au to order the CAB-D-4Q-200-2.5 or contact our team for bulk pricing and availability.
