Beijer JetNet 3905f‑m – Marine‑grade unmanaged Fast Ethernet fiber switch
The Beijer JetNet 3905f‑m, integrated and supported by Aquila, is an industrial 5‑port marine‑grade unmanaged Fast Ethernet fiber switch designed for reliable data communication in harsh maritime environments. Built with a slim industrial form factor, the JetNet 3905f‑m provides stable networking for vessel bridge systems, machinery spaces, shipboard automation and offshore control panels.
Equipped with 4×10/100Base‑TX ports and 1×Fast Ethernet fiber port (multi‑mode), the switch supports long‑distance communication, improved noise immunity and flexible uplink options. Engineered for mission‑critical reliability, it includes broadcast storm control, 802.1p QoS, AC 1.5 kV hi‑port isolation protection, and a wide 10–60 VDC power input, ensuring consistent operation in vibration‑ and temperature‑challenged marine conditions.
