CATV Front-end equipment CMTS supporting DOCSIS and Euro-DOCSIS

Summary

All D3 CMTS series from Jinghong are developed based on DOCSIS3.0 and C-DOCSIS protocols. There are kinds of product types such as rack mount, outdoor and D-node.

D3 series adopt channel binding technology, for downstream (DS), there are 16 QAM channels which has 1.1Gbps data rate; for upstream, there are 4 QPSK/QAM channels which could reach up to 160Mbps. D3’s downstream can be configured to data channels or IPQAM , for data port, there are 1000Mbps power port (RJ45) and 1000Mbps optical port (SFP), With three layer routing function, they can meet all kinds of working conditions and requirements from different operators.

Due to D3’s high bandwidth, perfect Qos, it is very suitable for IPTV or VOD, such kind of video service. It is cost effective for cut down cost then, add value for traditional HFC network.

There are three ways to manage D3:

n     CLI after log in via serial port or by telnet;

n     Remote log in embed web NMS;

n     External NMS server based on SNMP protocols which run windows OS.

D3 series can compatible with DOCSIS 2.0/3.0 cable modem.

JH-F3416 is the outdoor CMTS of D3 series, it is tailor made for those networks which deploy CMTS on optical nodes, it can be installed in simple machine room, sharing box even wall hanging. It has all core D3 functions and high performance, added more RF port in order to connect current optical equipment.

It is Chassis cooling mode, no fan rain-proof design, mute operation. The data port can connect upward to Ethernet and EPON. As to RF port, there are 4 TV IN for connecting TV signals from the optical receiver while other 4 RF OUT for connecting coaxial cable network.

The Outdoor CMTS forward lead the data signal and tv signal mixture from the machine room to optical node, narrowed the upstream funnel and reduced the noise interference accordingly. It can rapidly cover and connect all users without reconstructing original optical network structure.

Features

Compatible with DOCSIS3.0, C-DOCSIS standard, work with all cable modem based on DOCSIS, support both EURO DOCSIS and DOCSIS.

16 DS channels bound, 64/256/1024QAM modulation mode optional. Data rate could reach up to 1.1Gbps@1024QAM.

4 US channels bound, could be configured to QPSK, 3-8 grade QAM mode, data rate could reach up to 160Mbps.

Flexible on channels bound quantity set for convenient use of channel resource

Layer 3 routing functions, support static route, VLAN,NAT and DHCP relay agent

There are 1000M RJ45 port and SFP on data port which could be connected to not only EPON’s ONU but also Ethernet via optical port

There are a variety of RF interfaces which could be adapted to all kinds of optical nodes connection.

Built-in DHCP/TFTP server, support PPPoE.

Load balancing.

Support IPV6, multicast.

Qos based on service flow ensures bandwidth needs for various services.

Ensure network transmit safety via various kinds of methods such as BPI+, CM identification, anti-DOS attack , user  isolation and IP source checking .

Real time upstream spectral analysis function which helps to check US channel signal and noise status.

Support three management ways: CLI after log in via serial port or by telnet; Remote log in embed web NMS; External NMS server based on SNMP protocols which run windows OS.
