Ruckus Wireless E25G-SFP28-LR SFP28 Transceiver Module 25 Gigabit LAN

E25G-SFP28-LR - 25 Gb/s SFP28 Single-Mode LR Transceiver

Overview

The E25G-SFP28-LR is a high-speed optical transceiver module built for 25 Gigabit Ethernet (25GbE) over single-mode fiber (SMF), commonly used in enterprise data centres, campus backbones and service-provider interconnects. It supports a 1310 nm laser wavelength and a reach of up to approximately 10 km over standard OS2 SMF, making it ideal for wiring-closet to aggregation-switch links, long campus spans, or high-capacity server-to-switch uplinksAs an SFP28 module, this part fits directly into the standard SFP-style cage found in modern switches and routers, offering compatibility and flexibility without requiring a larger QSFP form factor. It includes Digital Diagnostic Monitoring (DDM/DOM) support, so network engineers can monitor optical power, temperature and voltage in real time × a key feature for packet-engineers managing large fibre infrastructuresWhen upgrading networks from 10Gb to 25Gb, or when deploying new 25Gb lanes in data centre leaf or spine fabrics, the E25G-SFP28-LR offers a cost-effective, standards-based solution. Its LR (Long Reach) classification ensures that you don't need parallel fibre or expensive DWDM gear for moderate distance runs, simplifying the fibre-plant and reducing maintenance overhead.
