Beijer JetNet 3905 – Marine‑grade unmanaged Fast Ethernet switch
The Beijer JetNet 3905, integrated and supported by Aquila, is a marine‑grade industrial 5‑port unmanaged Fast Ethernet switch designed for compact, reliable networking in vessel automation systems and offshore environments. Featuring 5 × 10/100TX ports with Auto MDI/MDI‑X, the JetNet 3905 supports flexible copper connectivity for bridge networks, machinery spaces, and distributed control panels.
With broadcast storm control, 802.1p QoS for traffic prioritization, AC 1.5 kV hi‑port isolation protection, and a wide 10–60 VDC power input, the JetNet 3905 delivers stable communication in harsh conditions where vibration, power fluctuations, and temperature variations are common. Its slim industrial design makes it ideal for confined maritime and offshore installations.
