Description

The CAB-D-4Q-200G-1M is a 1-metre passive Twinax copper breakout DAC cable designed for high-density 200G data centre interconnects. It splits a single 200GBASE-CR8 QSFP-DD port into four independent 50GBASE-CR2 QSFP connections, operating across 8 x 25G NRZ electrical lanes — delivering wire-speed performance with no active components, minimal latency, and near-zero power overhead. Purpose-built for Arista switching platforms running EOS 4.23.0 or later, it is ideal for connecting spine or leaf switches to server NICs or legacy 100G/25G infrastructure.

As a passive direct attach cable, the CAB-D-4Q-200G-1M is hot-swappable and certified across all supporting Arista platforms, with EEPROMs pre-programmed for 25Gb/s NRZ compatibility to ensure seamless interoperability with existing 100G QSFP and 25G SFP deployments. Available within a family spanning 1m, 2m, and 2.5m lengths, it provides flexible rack-scale cabling options. Order direct from iptrading.com.au — Australian-owned and operated since 2001.

FAQs

Q: What does this cable do?
A: The CAB-D-4Q-200G-1M is a breakout DAC cable that splits one 200GBASE-CR8 QSFP-DD port into four separate 50GBASE-CR2 QSFP connections. This allows a single 200G switch port to connect to four individual 50G devices, maximising port density and reducing cabling costs.

Q: Is this cable compatible with non-Arista equipment?
A: This cable is designed and certified for Arista platforms running EOS 4.23.0 or later. While the Twinax copper and QSFP/QSFP-DD form factors follow industry standards, Arista DAC cables are validated specifically for Arista switches and may not be supported by other vendors' platforms.

Q: Does this cable require any power or active electronics?
A: No. This is a fully passive Twinax copper cable with no active components. It draws negligible power, produces minimal heat, and delivers very low latency — making it an efficient choice for short-reach, high-density data centre deployments.

Q: What is the minimum EOS software version required?
A: The CAB-D-4Q-200G-1M requires Arista EOS version 4.23.0 or later on the host switch to be recognised and function correctly in breakout mode.

Q: Can this cable interoperate with legacy 100G or 25G infrastructure?
A: Yes. The cable's EEPROMs are programmed for 25Gb/s NRZ data rates, enabling compatibility with legacy 100G QSFP and 25G SFP ports. This makes it suitable for gradual migration scenarios where newer 200G Arista switches need to connect to existing server NICs or older switching tiers.

Q: Can I purchase this cable in Australia through IP Trading?
A: Yes. IP Trading is an Australian-owned and operated B2B IT hardware reseller based in Australia since 2001. The CAB-D-4Q-200G-1M can be ordered directly via iptrading.com.au, with expert pre-sales support available for compatibility and configuration queries.
