Connectivity and compatibility

This transceiver is designed to integrate smoothly with Arista switches and servers that support QSFP-40G-SR4 modules. The 12-strand MTP/MPO connector fits standard multimode fiber cabling, making it straightforward to connect within existing fiber optic networks. Its adherence to industry standards ensures reliable communication and interoperability across compatible devices.

Performance and reliability

The module’s zinc housing not only shields against electromagnetic interference but also helps dissipate heat, which is crucial for maintaining stable performance in busy network racks. The inclusion of Digital Diagnostic Monitoring allows network administrators to monitor the transceiver’s operational status in real time, enabling proactive maintenance and reducing the risk of unexpected downtime.

Ideal uses and environments

This transceiver is well suited to data centers and enterprise networks that require high-speed, short-range fiber optic connections. It fits environments where maintaining continuous network uptime is critical, such as server farms, cloud infrastructure, and high-performance computing clusters. Its compatibility with Arista equipment makes it a strong choice for organizations standardizing on that platform.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
