Eaton Tripp Lite Series Arista-Compatible QSFP-40G-SR4 QSFP+ Transceiver

Upgrade your data center with a high-performance QSFP-40G-SR4 transceiver designed for seamless integration with Arista switches. This Eaton Tripp Lite Series module delivers robust 40 Gbps Ethernet capability over multimode fiber, making it ideal for short-reach uplinks, spine-leaf backplanes, and server-to-switch connections in busy data centers. Built to the 40GBASE-SR4 standard, it leverages four parallel 10 Gbps lanes within a single QSFP+ package, enabling rapid scale-out of network bandwidth without wholesale cabling changes. The transceiver is engineered for reliability, interoperability, and easy deployment in mixed-vendor environments, reducing downtime and simplifying upgrades. Its design emphasizes compatibility with Arista ecosystems, ensuring straightforward plug-and-play operation in supported switches while maintaining the performance and stability that enterprise networks demand. Whether you are upgrading 10G links to 40G or expanding your 40G fabric, this module provides a dependable, low-friction path to higher throughput and improved latency characteristics across your data-center fabric.

• High-speed 40GBASE-SR4 over multimode fiber: Four parallel 10 Gbps lanes deliver up to 40 Gbps of aggregate bandwidth, optimized for short-reach interconnects within data centers. The SR4 approach enables efficient use of a single QSFP+ port to handle multiple 10G streams, simplifying cabling and reducing switch port density requirements while maintaining strong BER performance over MMF.
• Arista-compatible with cross-vendor interoperability: Specifically designed to work with Arista network switches and Arista-compatible environments, this transceiver supports plug‑and‑play deployment in supported hardware. It is tested for interoperability across common data-center gear, ensuring reliable operation in mixed-vendor infrastructures where fiber, optics, and switch hardware come from multiple vendors.
• MTP/MPO connector and multimode fiber readiness: The module uses an MTP/MPO connector and is intended for multimode fiber cable—ideal for OM3/OM4 installations. This setup supports streamlined, high-density cabling in racks and cabinets, enabling clean fiber management and straightforward termination in standard data-center pathways.
• 850 nm VCSEL technology with a 400 m reach: The transceiver employs 850 nm VCSEL emitters for short-reach MMF transmission, delivering stable performance across typical data-center trunking and horizontal cabling. A 400-meter reach over OM3/OM4 MMF makes it well-suited for most rack-to-rack uplinks and distribution paths found in enterprise environments that prioritize low latency and predictable link budgets.
• Plug-and-play reliability with easy maintenance: Engineered for hot-swappable installation in compatible switches, the module minimizes downtime during upgrades or maintenance windows. Its robust electro-optical components and standardized form factor support quick replacement and predictable behavior, helping IT teams maintain service levels while expanding bandwidth.

How to Install Eaton Tripp Lite Series Arista-Compatible QSFP-40G-SR4

To install, verify that your Arista switch port supports QSFP+ SR4 modules and that fiber cabling complies with OM3/OM4 MMF specifications. Power down is optional for hot-swappable deployments, but follow your equipment vendor’s guidelines; align the module with the QSFP+ slot and insert firmly until the latches engage. Attach the MTP/MPO MMF fiber bundle to the connector, ensuring proper polarity and gentle handling to maintain fiber integrity. Route cables with strain relief and avoid sharp bends to preserve signal quality. After seating the module, power on the device (if required) and monitor the port LEDs or the switch management interface for a 40G link indication. If the link does not come up, re-seat the module, check fiber polarity, verify lane mapping, and confirm that the fiber path is free of excessive loss or damage. Keep fiber connectors clean and use proper cleaning procedures to prevent performance degradation.
