Eaton Tripp Lite Series QSFP-40G-SR4 QSFP+ Transceiver - 40GBase-SR4, MTP/MPO MMF, 40 Gbps, 850 nm, 400 m (1312 ft.)

The Eaton Tripp Lite Series QSFP-40G-SR4 QSFP+ Transceiver is a top-tier networking module engineered to elevate data-center connectivity and deliver reliable, high-speed interconnectivity across dense switching environments. Designed for seamless integration with existing infrastructure, this 40 Gbps QSFP+ transceiver supports parallel 4x10G lanes, enabling high-capacity links between data-center switches, routers, and storage systems. With a focus on easy installation, broad compatibility, and robust performance, it’s an ideal upgrade for spine-leaf architectures, server-to-switch uplinks, and high-throughput workloads that demand low latency and consistent throughput.

• 40GBASE-SR4 performance in a compact QSFP+ package: Four parallel 10Gbps lanes combine to deliver a full 40 Gbps data rate, enabling high-bandwidth interconnects between switch ports and high-speed servers without sacrificing port density or flexibility. This multi-lane design supports scalable deployments in modern data centers and enterprise networks, making it easier to upgrade from 10G to 40G without changing fiber infrastructure.
• 850 nm VCSEL technology and MMF compatibility: The transceiver uses 850 nm vertical-cavity surface-emitting laser emitters optimized for multimode fiber, providing reliable, high-speed transmission over OM3/OM4 cables with MTP/MPO connectors. The result is lower insertion loss, improved signal integrity, and an efficient pathway for moving large data sets between devices in a rack or across rows.
• Long reach on multimode fiber: Engineered to operate across OM3/OM4 multimode fiber up to 400 meters, this module extends the reach of 40 Gbps links while maintaining strong link budgets and minimal error rates. Ideal for data-center backbones and intermediate connections in multi-rack deployments, it supports robust performance in complex topologies.
• Plug-and-play and broad compatibility: The transceiver is designed to slot into QSFP+ ports across major networking platforms. It supports easy hot-plug capability, and its compatibility spans leading vendors like Cisco, Juniper, Arista, and others, reducing integration time and avoiding driver complications. Organizations benefit from smoother upgrades and simplified inventory management.
• Durable, enterprise-grade construction: Built to withstand the demands of dense racks and high-availability environments, the module features robust mechanical design, effective thermal management, EMI shielding, and ESD protection to minimize downtime and maintenance needs. These attributes help ensure reliable operation in data centers, colocation facilities, and high-demand compute clusters.

How to install Eaton Tripp Lite QSFP-40G-SR4 Transceiver

• Power down the host equipment or verify that the device supports hot-swapping for QSFP+ modules. Ground yourself to prevent ESD damage before handling the transceiver.
• Remove the QSFP+ port cover or latch from the switch, router, or server if applicable. Handle the transceiver by the top and bottom edges to avoid touching the electrical contacts.
• Align the QSFP-40G-SR4 module with the target port. Gently slide the transceiver into the QSFP+ slot until it seats securely with a click or until the latching mechanism engages.
• Attach the MTP/MPO multimode fiber cable to the transceiver’s optical interface. Ensure the connector is clean and free of dust, and maintain proper polarity and fiber order to preserve signal integrity.
• Route fiber cables with attention to bend radii; secure cables to prevent movement that could loosen connections. Reinsert any port covers or latches as required by your equipment.
• Power on or resume operation of the device. Verify link lights or management software indicators confirm a successful connection, and perform a baseline throughput test to ensure the link meets expected performance levels.

Frequently asked questions

• Q: What is 40GBASE-SR4? A: 40GBASE-SR4 is a 40 Gbps, parallel optical transceiver standard that uses four 10 Gbps lanes over multimode fiber with an MTP/MPO connector, typically used for short-reach connections within data centers and high-density network deployments.
• Q: Which fiber and connector does this transceiver require? A: It requires multimode fiber (MMF) with an MTP/MPO connector, commonly OM3 or OM4, to achieve the listed reach and performance.
• Q: What is the maximum distance supported? A: The transceiver supports up to 400 meters on OM3/OM4 MMF, depending on fiber quality and system design. Distances beyond manufacturer-recommended limits may require active, system-specific validation.
• Q: Is this transceiver hot-swappable? A: Yes. It is designed for hot-swappable insertion in compatible QSFP+ ports, allowing non-disruptive upgrades in many data-center environments. Always follow your equipment vendor’s ESD and safety guidelines.
• Q: Is it compatible with multiple vendors? A: The QSFP-40G-SR4 transceiver format is broadly supported across major vendors (for example Cisco, Juniper, Arista, and others). Always verify interoperability with your specific switch or router model and firmware version to ensure optimal performance.
