Edwards 4-NET-SMH Single-Mode Fibre Optic SFP Network Controller, High Output

The Edwards 4-NET-SMH is a high-output single-mode, dual-fibre SFP network controller for the Edwards EST4 life safety control platform. It links panels over a 9/125 µm (G.652) single-mode fibre pair up to 40 km apart. Order one for the 'in' wiring from the previous node and a second for the 'out' wiring to the next node.

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
• High-output transceiver for distances up to 40 km
