The Nokia 474902A.101 SFP28 module enables high-bandwidth 25G (and some lower data-rate modes) connectivity over single-mode fiber up to approximately 10 km. It uses a 1310 nm DFB transmitter with a PIN photodiode receiver, supports digital diagnostics (DOM/DDM) and is designed for industrial temperature range (-40 °C to +85 °C). Suitable for carrier, data-centre and fronthaul applications where long-reach, single-mode links are required.
