CT22120VF voice fiber optical multiplexer is the new generation fiber optical transmission and access equipments which apply the latest technology and professional super-sized programmable integrate circuit. It provides E1 digital channels, PCM voice transmission and RS232 digital transmission. Get over the times of simplex user’s interfaces of traditional fiber equipments. All the user cards can be inserted to main board slots so that users can configure requirement business interfaces flexible. It can let user assembled his equipment as E1 interface, V.24 interface or VF interface expediently. When user don’t need VF interfaces, it also can provides 4×E1 channels. This multiplexer is a convenient equipment that widely used in public operator networks and private networks such as railway, banking, government and electric power etc.
