Features and applications
  • High performance: The module delivers 40 Gbps throughput by using four coarse wavelength division multiplexing (CWDM) lanes, each running at 10 Gbps.
  • Long-distance reach: The QSFP-40G-LR4 is designed for long-distance data transmission over single-mode fiber, making it suitable for interconnecting data centers, enterprise campuses, and core networks.
  • Reliable monitoring: Digital Diagnostics Monitoring (DDM) allows network administrators to monitor the real-time operating parameters of the transceiver, such as temperature, voltage, and optical power.
  • Broad compatibility: While often associated with Cisco, it is designed to comply with Multi-Source Agreement (MSA) standards, ensuring interoperability with various networking equipment.
