| Extreme Networks’ 25GBASE-ESR is an SFP28 transceiver designed for 25G Ethernet networks requiring greater range than standard SR optics. This module uses a multimode fiber (MMF) interface and typically operates over OM4 fiber, extending reach to 200 meters or more depending on fiber quality and conditions.
It supports a data rate of up to 25.78125 Gbps and is hot-pluggable, providing ease of installation and minimizing network downtime. Digital Diagnostic Monitoring (DDM) is built-in, allowing administrators to monitor optical performance in real time. The module is fully compliant with MSA and IEEE 802.3by standards and fits seamlessly into high-speed aggregation or core layers within enterprise environments. It operates with low power consumption (<1W), within a commercial temperature range of 0°C to 70°C. This makes it a reliable and scalable solution for extending 25G services further without transitioning to single-mode fiber. |
