Beijer JetNet 3905f‑s – Marine‑grade unmanaged Fast Ethernet single‑mode fiber switch
The Beijer JetNet 3905f‑s, integrated and supported by Aquila, is an industrial 5‑port marine‑grade unmanaged Fast Ethernet fiber switch (single‑mode) designed for compact and reliable shipboard and offshore networks. Its slim industrial housing and fanless design make it ideal for tight spaces such as bridge panels, machinery cabinets and distributed marine control enclosures.
With 4 × 10/100Base‑TX ports and 1 × Fast Ethernet single‑mode fiber port, JetNet 3905f‑s enables long‑distance, noise‑resilient communication between bridge systems, engine‑room equipment and offshore modules. Features such as broadcast storm control, 802.1p QoS, AC 1.5 kV hi‑port isolation protection and a wide 10–60 VDC power input ensure stable operation in harsh marine environments and variable power systems.
