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

The Eaton Tripp Lite Series Cisco-Compatible QSFP-40G-SR4 QSFP+ transceiver delivers high-density, high-speed connectivity designed for modern data centers and enterprise networks. Built to work seamlessly with Cisco switches and servers, this QSFP+ module enables reliable 40 Gbps uplinks over multimode fiber (MMF) with MTP/MPO connections. Its Cisco-compatible design ensures swift integration into existing infrastructure, minimizing downtime while maximizing throughput for applications ranging from virtualization and cloud services to large-scale data analytics. Engineered for performance, this transceiver supports 40GBase-SR4 operation across short to mid-range multimode fiber links, delivering robust, low-latency links essential for dense, latency-sensitive networks.

• Experience true 40 Gbps performance with a 40GBase-SR4 transceiver that supports high-bandwidth uplinks between core switches, access switches, and high-density servers. The QSFP+ form factor and SR4 optics enable parallel transmission across four lanes, providing the bandwidth needed for virtualization, storage-area network traffic, and clustered applications. This makes it ideal for data centers adopting 40G or preparing for 100G upgrades, while preserving investment in existing multimode fiber cabling.
• Designed for Cisco environments, this transceiver is engineered to be Cisco-compatible, ensuring plug-and-play compatibility with Cisco switches and servers. By adhering to the SR4 standard and using a familiar QSFP+ interface, it minimizes compatibility concerns, reduces deployment risk, and simplifies inventory management for IT teams responsible for mixed vendor ecosystems.
• Built for precision fiber connectivity, the transceiver uses 850 nm wavelength optics to deliver high-quality signals over multimode fiber. Paired with MTP/MPO MMF cabling, it enables reliable, high-bandwidth links up to 400 meters (1312 feet). This reach makes it suitable for data-center topologies that require short- to mid-range fiber runs between aggregation switches, servers, and storage arrays while maintaining low insertion loss and strong signal integrity.
• Installation and operation are streamlined for busy data centers. The QSFP+ package supports hot-swappable deployment in compatible devices, with rugged housing and reliable thermal performance. LED indicators provide quick status checks, while standard management tools and vendor documentation help administrators verify link status, data rate, and transceiver health without complicated downtime or specialized procedures.
• Cost efficiency and future-proofing are central to its value proposition. By leveraging a 40 Gbps SR4 interface over existing MMF fiber and ensuring compatibility with Cisco infrastructure, organizations can consolidate cabling and ports while laying groundwork for future upgrades to higher speeds. The Transceiver’s robust design supports sustained performance under typical data-center load, balancing speed, density, and reliability in a cost-conscious deployment.

how to install Eaton Tripp Lite Series Cisco-Compatible QSFP-40G-SR4 QSFP+ Transceiver

• Verify compatibility with your Cisco device and confirm that the port supports a QSFP-40G-SR4 transceiver. Ensure you have the correct MMF fiber cable (MTP/MPO) and the appropriate fiber OM classification (commonly OM3 or OM4 for SR4 links).
• Power down optional: In many modern systems, QSFP+ modules are hot-swappable. If your device supports hot-swapping, you can proceed with the transceiver installed while the system is powered. If not, power down the device according to your vendor’s guidelines before installation.
• Align and insert: Remove the protective caps, align the QSFP-40G-SR4 transceiver with the QSFP+ slot, and firmly insert it until it seats securely with a click. Ensure the module sits straight and parallel to the slot to avoid damage to the connector or slot.
• Connect fiber: Attach a compatible MTP/MPO MMF fiber cable to the transceiver’s optical interface. Verify that the fiber polarity is correct and that the fiber cables are clean and free from dust or debris to maintain signal integrity.
• Power on and verify: If the device was powered on, monitor the port LEDs or management interface to confirm the link comes up. On Cisco devices, use appropriate commands (for example, show interface transceiver details or show interfaces status) to confirm the transceiver is recognized and operating at 40 Gbps with the SR4 lanes active.
• Manage and test: Run connectivity tests to verify throughput and latency. If needed, perform a basic loopback test or use performance monitoring tools to validate SR4 link performance. If issues arise, recheck fiber cleanliness, connector seating, and compatibility with the Cisco IOS version and hardware revision.
