Teltonika PR4DU22K SR SFP Transceiver
Overview
Teltonika PR4DU22K is a 1.25 Gbps short‑reach SFP optical transceiver used to connect Ethernet switches and routers over multimode fiber for network engineers deploying fiber uplinks or aggregation links. It operates at the 850 nm wavelength and supports standard 50/125 µm multimode fiber with a duplex LC interface, extending links up to approximately 550 m. Its industrial‑grade temperature and humidity specifications allow use in edge racks, telecom closets, and harsh environments without dedicated climate control. The module plugs into standard SFP slots on compatible network equipment.
