EON Technology 25G SFP28 duplex transceiver modules are the standard choice for server-to-network-platform links and leaf-spine architectures in modern data centers. They support 25GBASE-SR (100 m MMF), 25GBASE-LR (10 km), ER (40 km) and ZR (80 km) with an LC duplex connector, plus 10G/25G variants for dual-speed ports. Compatibility validated by model, firmware, port and optical part number.
Key features
