The 400G-LR4-QSFPDD10KM transceiver from Extreme Networks is engineered for high-speed 400 Gigabit Ethernet transmission across single-mode fiber (SMF) links up to 10 kilometers. Featuring the compact QSFP-DD form factor and utilizing 4x100G PAM4 modulation on LAN-WDM wavelengths, this transceiver is ideal for core, metro, and data center interconnect applications requiring extended reach and high throughput.
Designed to comply with IEEE 802.3cn standards, the LR4 module offers reliable, low-latency connectivity and supports breakout functionality to 4x100G lanes. The hot-swappable design allows for easy maintenance and upgrades without network downtime. Integrated digital diagnostics monitoring (DDM) provides real-time performance insights including temperature, voltage, and optical power levels to ensure stable operation.
This module is optimized for dense, energy-efficient deployments in hyperscale cloud environments, carrier networks, and enterprise backbones. With low power consumption and robust signal integrity, the 400G-LR4 transceiver delivers a cost-effective solution for long-haul, high-bandwidth networking needs.
