The Extreme Networks 100G-ESR4-QSFP300M transceiver from Extreme Networks is designed for extended short-range 100 Gigabit Ethernet transmission over multimode fiber optic cables, supporting distances up to 300 meters on OM4 fiber. Using four 25 Gbps lanes per QSFP module, it offers high-speed connectivity suitable for larger data center environments and campus networks.
Compliant with IEEE 802.3bm specifications, the ESR4 module provides enhanced reach compared to standard SR4 optics, enabling longer fiber runs without signal degradation. The module features hot-swappable capability and digital diagnostics monitoring (DDM) for real-time health insights on optical parameters and device status.
This transceiver is optimized for low latency and power-efficient operation, making it ideal for enterprise aggregation layers, data center spine switches, and inter-rack connections that require robust performance and scalability.
