Description

The Arista CAB-O-8S-200G-3M is a 200GBASE-CR8 passive twinax copper DAC breakout cable designed for high-density data centre deployments. It connects a single OSFP port — operating at 200G across 8 x 25G NRZ electrical lanes — to eight 25GBASE-CR SFP28 ports over a 3-metre reach. This plug-and-play solution eliminates optics qualification cycles and delivers ultra-low power consumption with no active components, making it ideal for spine-to-server and top-of-rack connectivity in Arista-powered environments.

Fully integrated with Arista EOS and CloudVision, the CAB-O-8S-200G-3M supports interoperability with legacy 100G QSFP and 25G SFP infrastructure, enabling flexible migration paths without a full infrastructure overhaul. The EEPROM is pre-programmed to signal 25G NRZ format and maximum data rate for seamless compatibility with connected NICs and switches. Backed by Arista's 1-Year Limited Hardware Warranty with optional Next Business Day and 4-Hour Advance Hardware Replacement support.

FAQs

Q: What does the CAB-O-8S-200G-3M connect?
A: It connects a single OSFP port (configured for 200G using 8 x 25G NRZ lanes) to eight individual 25GBASE-CR SFP28 ports, making it a 1-to-8 breakout cable for high-density data centre environments.

Q: Does this cable require any active components or external power?
A: No. The CAB-O-8S-200G-3M is a fully passive twinax copper cable with no active electronics, resulting in minimal power draw and high reliability.

Q: Which Arista EOS version is required for this cable?
A: The minimum supported EOS version is 4.23.0. It is fully integrated with Arista EOS and CloudVision for seamless management and monitoring.

Q: Is this cable compatible with non-Arista equipment?
A: The cable's EEPROM is programmed to indicate 25G NRZ signal format, making it compatible with legacy equipment and NICs that recognise DACs programmed for 25 Gb/s data rates — enabling interoperability with existing 25G SFP28 infrastructure.

Q: What warranty does the CAB-O-8S-200G-3M carry?
A: It is backed by Arista's 1-Year Limited Hardware Warranty covering parts, repair, or replacement with a 10 business day turnaround. Optional Next Business Day and 4-Hour Advance Hardware Replacement support services are also available.
