The Extreme Networks 40G-ESR4-QSFP400M-NT module is a high-performance QSFP+ optical transceiver designed to deliver 40 Gigabit Ethernet over multimode fiber with an extended reach of up to 400 meters. Leveraging parallel optics and MPO connector technology, it transmits data over four lanes at 10Gbps each, compliant with IEEE 802.3ba 40GBASE-ESR4 standards. This extended reach transceiver supports OM4 multimode fiber, making it perfect for large-scale data centers, research facilities, and campus backbone applications where longer fiber runs are required.
The module supports hot-pluggability and Digital Diagnostic Monitoring (DDM), enabling easy installation and proactive management. With low power consumption and rugged construction, it provides reliable, high-speed connectivity while maintaining energy efficiency.
