Description

The Arista CAB-O-2Q-200G-2M is a 200GBASE-CR8 to 2x 100GBASE-CR4 passive Twinax Direct Attach Copper breakout cable designed for high-density data centre interconnects. It splits a single OSFP 200G port into two independent 100G QSFP ports, enabling seamless connectivity between next-generation Arista switches and servers or NICs equipped with legacy 100G QSFP interfaces — with zero active components and minimal latency.

Operating across 8x 25G NRZ electrical lanes, this 2-metre passive DAC requires no power conversion and supports hot-swapping for maximum uptime. Each connector includes an EEPROM programmed for 25G NRZ data rates to ensure full compatibility with legacy 100G and 25G equipment. Minimum EOS version 4.23.0 is required.

FAQs

Q: What does the Arista CAB-O-2Q-200G-2M cable do?
A: It is a passive Twinax Direct Attach Copper breakout cable that connects a single 200G OSFP port on an Arista switch to two separate 100GBASE-CR4 QSFP ports, enabling high-density, low-latency interconnects between next-generation and legacy infrastructure.

Q: Is this cable active or passive?
A: The CAB-O-2Q-200G-2M is a fully passive DAC cable. It contains no active electronic components, resulting in lower power consumption and minimal signal latency compared to active optical cables.

Q: What EOS software version is required to use this cable?
A: Arista EOS version 4.23.0 or later is required for the OSFP port to be correctly configured for 200G operation using 8x 25G NRZ electrical lanes.

Q: Can this cable connect to non-Arista equipment?
A: Yes. Each QSFP connector is programmed with an EEPROM for 25G NRZ data rates, which ensures compatibility with legacy 100G QSFP interfaces from other vendors. However, interoperability should be validated against your specific equipment.

Q: What lengths are available for this cable?
A: The OSFP to 2x QSFP passive DAC breakout cable is available in 1-metre, 2-metre, and 3-metre lengths. The CAB-O-2Q-200G-2M is the 2-metre variant.

Q: Can I purchase the Arista CAB-O-2Q-200G-2M in Australia?
A: Yes. IP Trading is an Australian B2B IT hardware reseller stocking authentic Arista networking products including DAC and breakout cables. Order via iptrading.com.au for reliable supply and local service support.
