Description
The WDM-4140 CATV is a new compact (1RU only) chassis and cost-effective DVB-ASI re-multiplexer with IP output, The WDM-4140 has eight DVB-ASI inputs and two dual independent DVB-ASI outputs. The maximum input rate up to 108Mbps on each input, and output rate is adjustable from 0Mbps to 108Mbps according to different requirements. The WDM-4140 also supports 10/100/1000BASE-T IP output with rate auto-negotiation. The WDM-4140 has very convenient and friendly management interface, the user can complete all operation via local keyboard and LCD display on device, or access through the connection between the Ethernet port on device and the management computer.
