Docsis 3.0 cable modem

Specifications

• Adopting incorporates channel bundling technique
• D3 series has as much as 16 QAM downstream channels
• With 1.1Gbps data rate and 4 QPSK/QAM upstream channels
• With maximum of 160Mbps data rate
• D3 downstream channel can be flexibly configured to data channel or IPQAM channel
• Data interfaces include not only 1000Mbps port (RJ45), but also 1000Mbps SFP
• Addition, has 3-layer routing function and perfect QoS mechanism which enables them to be adapted to various environment and various strategies of operators
• Due to high bandwidth of D3 and its perfect QoS, D3 CMTS are quite
• Suitable for transmission on IPTV or VOD video service
• Can greatly reduce cost of operators so that they can achieve extra value to their inherent HFC network
• There are three ways to manage D3
• First one is to log-in on machine through telnet, then use command line (CIL) to assign configuration management
• Second one is remote log-in to equipment through web
• Last one is network management software based on QAM protocol
• D3 series are compatible with DOCSIS1.0/1.1/2.0/3.0 standard cable modem
• 19-inch 1U chassis CMTS which is specifically designed for deployment in front end
• When broadband user number is not much, this deployment will expand coverage area
• Design of completely independent upstream channel avoids mixture of noise and is available to decrease noise by 8dB
• Owns large screen panel so that display of configuration parameter, equipment operation state, uplink spectrum analysis and other information can be intuitive and real-time
