Description

The Arista CAB-O-4Q-200G-1M is a 200G passive Direct Attach Copper (DAC) breakout cable designed for high-density data centre and HPC environments. It connects a single 200GBASE-CR8 OSFP port — operating across 8 x 25G NRZ electrical lanes — to four 50GBASE-CR2 QSFP ports, enabling efficient 200G-to-4x50G port breakout without any active components or power consumption.

As a plug-and-play, hot-swappable solution, this cable simplifies migration and infrastructure consolidation by providing seamless interoperability with legacy 100G QSFP and 25G SFP deployments. EEPROM-programmed for 25G NRZ data rates, it ensures broad device compatibility and requires a minimum of Arista EOS 4.23.0. Available now at iptrading.com.au — competitive prices and local support.

Features

- Passive design — zero power consumption and minimal latency for cost-efficient deployments

FAQs

Q: What does the CAB-O-4Q-200G-1M connect?
A: It connects a single 200GBASE-CR8 OSFP port on a switch or line card to four 50GBASE-CR2 QSFP ports, enabling a 1-to-4 port breakout across 8 x 25G NRZ electrical lanes.

Q: Does this cable require any power or external configuration?
A: No. It is a fully passive design with 0W power consumption. The EEPROM is pre-programmed for 25G NRZ data rates, making it plug-and-play with no additional configuration required beyond ensuring the OSFP port is configured for 200G mode.

Q: What Arista EOS version is required?
A: A minimum of Arista EOS version 4.23.0 is required for proper operation of this cable.

Q: Can this cable interoperate with legacy 100G QSFP or 25G SFP infrastructure?
A: Yes. The cable is EEPROM-programmed for 25G NRZ data rates, enabling interoperability with legacy 100G QSFP and 25G SFP ports, making it ideal for infrastructure migrations and phased upgrades.

Q: Is the CAB-O-4Q-200G-1M available in other lengths?
A: Yes. Arista offers this breakout cable series in 1m, 2m, and 3m lengths to suit varying rack and cabinet distances in data centre environments.

Q: Can I purchase this cable in Australia from IP Trading?
A: Yes. The Arista CAB-O-4Q-200G-1M is available now at iptrading.com.au. IP Trading is an Australian B2B IT hardware reseller offering competitive pricing and local support for Arista networking products.
