The Extreme Networks 40G-QSFP-ER4-1 transceiver module is a high-power, long-reach QSFP+ optical solution supporting 40 Gigabit Ethernet transmission over single-mode fiber for distances up to 40 kilometers. It uses four 10 Gbps lanes multiplexed to provide a combined 40G throughput, conforming to IEEE 802.3ba and Multi-Source Agreement (MSA) standards. Engineered for carrier-grade and large-scale data center applications, the ER4-1 module delivers ultra-low latency and robust signal integrity, minimizing dispersion and electromagnetic interference.
Its hot-swappable form factor ensures easy integration and maintenance without interrupting network operations. Designed with power efficiency in mind, it balances high performance with low energy consumption, supporting scalable metropolitan area networks and long-haul data center interconnects. This transceiver is ideal for enterprises and service providers requiring reliable, high-bandwidth, extended-distance optical networking solutions.
