Frequently Asked Questions

What is the primary application for the Arista QSFP-100G-DZ2-31 transceiver? +

The Arista QSFP-100G-DZ2-31 is designed for high-density 100G Ethernet applications, specifically leveraging DWDM technology. It is ideal for data center interconnects and metro area networks where you need to transport high-bandwidth traffic over long distances across dense wavelength division multiplexed fiber infrastructures.

Does the QSFP-100G-DZ2-31 support standard QSFP28 switch ports? +

Yes, this module is built to the QSFP28 form factor, making it natively compatible with any Arista switch or router port that supports the QSFP28 standard. It provides a seamless transition for upgrading legacy 10G or 40G links to high-performance 100G DWDM connectivity within your existing chassis.

What is the key performance benefit of using this DWDM module? +

This module enables the multiplexing of multiple 100G channels over a single fiber pair, significantly increasing the capacity of your existing fiber plant. By utilizing advanced DWDM capabilities, it allows network architects to scale bandwidth effectively without the need to lease or install additional dark fiber, optimizing long-term infrastructure investment.

Is the QSFP-100G-DZ2-31 compatible with third-party optical multiplexing equipment? +

Designed to operate within standardized ITU grid environments, this transceiver works well with most industry-standard passive and active DWDM multiplexing systems. It provides reliable, standards-compliant signals, ensuring interoperability across mixed-vendor optical transport layers when integrated into broader wavelength-division architectures.

How is the power consumption managed on this 100G DWDM transceiver? +

The module is engineered for power efficiency, adhering to the power envelope specifications typical for QSFP28 DWDM optics. While it requires more power than standard short-reach transceivers due to the complex modulation needed for long-haul DWDM, it remains within the thermal design parameters of standard high-density Arista line cards.

What level of signal integrity can I expect from the Arista QSFP-100G-DZ2-31? +

This transceiver delivers high-fidelity signal transmission designed to minimize chromatic dispersion and optical noise. By maintaining strict adherence to Arista’s stringent optical quality standards, it ensures stable, low-latency performance essential for demanding enterprise and carrier-grade applications over extended reach fiber spans.

Does this module require specific switch software or licensing? +

Generally, this module is recognized by Arista EOS upon insertion. While hardware compatibility is straightforward, ensure your Arista switch or router is running an EOS version that supports the specific 100G DWDM transceiver profile. You should verify your current switch software version against the Arista release notes to ensure full feature compatibility.

What environmental conditions are necessary for optimal transceiver reliability? +

To ensure peak performance and longevity, these modules should operate within standard data center temperature and humidity ranges. Proper airflow management in the rack is crucial, as optical modules are sensitive to heat buildup. Maintaining a clean fiber environment will also prevent signal degradation and ensure reliable link stability.

Can I receive a bulk quote for large quantities of the QSFP-100G-DZ2-31? +
