Beijer JetCon 3701 Series – Industrial Gigabit PoE media converters
The Beijer JetCon 3701 Series, integrated and supported by Aquila, consists of industrial‑grade Gigabit Ethernet/fiber media converters designed for long‑distance, noise‑resilient communication in marine, offshore and harsh‑environment industrial networks.
Models include:
JetCon 3701G – Rugged 1000Base‑TX to SFP Gigabit media converter
JetCon 3701GP‑U – High‑power IEEE 802.3bt PoE+ (up to 90W) Gigabit media converter
Both variants operate from ‑40°C to +75°C, feature dual power inputs with real‑time power backup for non‑stop Ethernet transmission, and support two‑way Link Loss Forwarding (LLF) to ensure failures propagate correctly for fast recovery. A flexible SFP slot allows the use of single‑mode or multi‑mode fiber for extended‑distance transmission.
The durable, slim IP‑31 protected housing makes the JetCon 3701 Series suitable for compact bridge cabinets, machinery spaces, offshore modules and industrial control panels.
