Laying optical fiber from the monitoring room to the access switch. Two-layer network architecture, namely: core layer-access layer. The access switch is connected in gigabit and in 100 megabit. Core switch, equipped with 10 or above optical interface board, 12 gigabit electrical interface board, engine module, dual power supply module, etc.
