The 40Gb/s QSFP+ transceivers are designed for high-bandwidth data transport across modern networking environments including data centers, high-performance computing, and InfiniBand systems. These modules offer flexibility with multiple variants for short-reach, extended-reach, and long-range optical links.

With support for 4-lane parallel or CWDM multiplexing technologies, the transceivers can operate over multimode or single-mode fiber, depending on the model. Designed for compactness and low power consumption, they ensure optimal port density and thermal efficiency in high-density switch and server environments.

Models such as SR4 and eSR4 support up to 300m on multimode fiber, while LR4 and PSM LR4 extend connectivity up to 10Km on single-mode fiber. All units comply with QSFP+ MSA standards and offer integrated digital diagnostics for performance monitoring.

Ideal for scalable Ethernet infrastructure and high-throughput computing applications, these transceivers combine speed, efficiency, and long-term reliability.
