Edwards 4-NET-SMU Single-Mode Fiber-Optic SFP Network Controller Bi-Directional

The Edwards 4-NET-SMU is a bi-directional single-mode, single-fibre SFP network controller (uplink) for the Edwards EST4 life safety control platform. It links panels over one 9/125 µm (G.652) single-mode fibre up to 10 km, and must be paired with a 4-NET-SMD (downlink) at the other end.

EST4 4-NET series controllers are hot-swappable SFP transceivers that set the physical cable type between panels. They plug into either of the two SFP slots on the 4-CPU, 4-ANNCPU, 4-CPUGRPH and 4-NET-AD modules, and one network cable carries panel data, voice audio and firefighters' telephone. If a connected CPU goes offline, the input and output ports connect directly to each other, keeping basic network connectivity.

Key features

• Hot-swappable SFP network controller
• Carries panel data, voice audio and firefighters' telephone on the same fibre
• Pass-through mode keeps connectivity if a panel CPU goes offline
• Self-configuring IPv6 network; supports Class A, B, X and N configurations
• Can be mixed with copper, CAT5 and other fibre controllers on the same network
• Uses a single fibre for both directions, paired with a 4-NET-SMD
