Edwards 4-NET-MM — EST4 SFP network controller, multimode, dual-fiber, 100Base-FX, 1310 nm.
EST4 panels and annunciators connect over the EST4 network, and a single network cable carries all panel-to-panel services: data, voice audio and firefighter telephone. The network controller is chosen to match the installed cable, and the 4-NET-MM is the plug-in SFP for multimode fiber links. Copper, single-mode and multimode links can be combined on the same network.
