QSFP+ 40G SMF Optical Transceiver for Long-Range Single-Mode Fiber Networks - Compatible with Cisco and MSA

The 40G QSFP+ Optical Transceiver Module from Intellinet Network Solutions is designed to deliver reliable high-speed connectivity for modern enterprise, campus, telecom, and cloud network environments. Supporting the IEEE 802.3ba 40GBASE-LR4 Ethernet standard, it enables data transfer rates up to 40 Gbps over single-mode fiber connections with transmission distances of up to 10 km (6.2 mi.). Its compact QSFP+ form factor makes it ideal for high-density network infrastructures requiring scalable and efficient 40G connectivity.

Optimized for Long-Distance 40G Ethernet Connectivity

Featuring one LC duplex single-mode fiber port and operating at a wavelength of 1310 nm, the transceiver is engineered for stable long-distance optical communication. The LR4 design uses advanced wavelength multiplexing technology to support high-bandwidth data transmission over standard duplex single-mode fiber, making it suitable for backbone, aggregation, and core network applications across large campuses, datacenters, and telecom infrastructures.

Broad Compatibility with Leading Network Platforms

The module is MSA-compliant to ensure seamless interoperability with a wide range of switches, routers, and networking equipment from leading manufacturers including Cisco, Intellinet Network Solutions, ZyXEL, TP-Link, Ubiquiti, and more. Equivalent to the Cisco QSFP-40GE-LR4 transceiver model, it provides a reliable and cost-effective solution for expanding or upgrading existing 40G network deployments while maintaining compatibility with established hardware ecosystems.

Advanced Monitoring and Reliable Operation with DDM / DOM

Integrated digital diagnostics monitoring (DDM) and digital optical monitoring (DOM) functions provide real-time access to critical operating parameters such as temperature, voltage, and optical signal levels. This allows administrators to monitor transceiver performance and simplify network maintenance and troubleshooting in demanding enterprise and datacenter environments.

Durable Design for Enterprise and Datacenter Environments

A fully metallic housing minimizes electromagnetic interference (EMI) and enhances durability for stable operation in high-performance networking applications. Hot-plug support allows the transceiver to be installed or replaced without shutting down connected equipment, reducing maintenance downtime and improving service continuity in mission-critical network infrastructures.
