Frequently Asked Questions

What is the primary application for the Arista QSFP-40G-XSR4 transceiver? +

The Arista QSFP-40G-XSR4 is an extended reach 40GBASE-SR4 transceiver designed for high-density data center environments. It is ideal for short-reach multi-mode fiber links, specifically optimized for interconnecting 40GbE switches and servers within a rack or across adjacent rows, providing reliable connectivity for bandwidth-intensive applications.

Does the QSFP-40G-XSR4 support breakout configurations for 10G connections? +

Yes, this module supports 4x10G breakout functionality when paired with the appropriate MPO-to-LC fiber harness cables. This flexibility allows network architects to transition from 10G server uplinks to 40G core switching architectures seamlessly, effectively utilizing the transceiver's four lanes for multiple discrete data streams.

What type of optical fiber cabling is required for this Arista QSFP+ module? +

This module requires OM3 or OM4 multi-mode fiber cabling terminated with an MPO-12 connector. While the reach varies depending on the specific fiber type utilized, adhering to industry-standard fiber quality is essential to maintaining the low bit error rates expected in high-speed Arista switching infrastructures.

How does the performance of the XSR4 compare to standard SR4 transceivers? +

The XSR4 designation indicates an extended reach capability compared to standard 40GBASE-SR4 modules. This makes it a preferred choice for enterprise data centers where cable runs may slightly exceed the typical 100-meter limits of standard SR4 optics, providing added design flexibility without moving to more expensive single-mode fiber solutions.

Is the QSFP-40G-XSR4 compatible with third-party network switches? +

While specifically engineered for Arista Networks hardware to ensure optimal performance and diagnostic reporting, the module adheres to the QSFP+ Multi-Source Agreement (MSA). However, for mission-critical production environments, we strongly recommend using this transceiver within Arista platforms to ensure full compatibility with Arista EOS software and seamless hardware handshaking.

What is the power consumption profile for this 40G optical module? +

The QSFP-40G-XSR4 is designed for high efficiency, typically consuming less than 1.5 watts of power. This low thermal footprint is critical for high-density switches where port counts are maximized, helping to maintain optimal operating temperatures within the chassis and reducing the overall energy costs of your rack deployment.

What kind of management and diagnostic features does this module offer? +

This transceiver includes Digital Optical Monitoring (DOM) capabilities, allowing administrators to access real-time performance metrics via the Arista switch command line. You can monitor critical parameters such as optical output power, input power, transceiver temperature, and supply voltage, enabling proactive troubleshooting and maintenance before performance degradation occurs.

What is the maximum operating temperature for the Arista QSFP-40G-XSR4? +

The module is rated for standard commercial operating temperatures, typically ranging from 0°C to 70°C. To ensure consistent performance and maximum module longevity, it is essential to maintain proper airflow within your switch chassis and follow standard data center environmental control protocols to prevent thermal throttling or signal instability.

How can I obtain a bulk quote for multiple Arista QSFP-40G-XSR4 units? +
