JH-DN3416B

JH-DN3416B is the latest version of D-Node, a multi-task outdoor node integrated with CMTS, CATV optical receiver, and ONU. D-Node has two fiber optical ports for upper link to the data center, one for CATV fiber, and the other is for IP traffic. D-Node has four RF ports for cable connection which connect to the access network. D-Node is responsible for CATV signal optical-to-electrical conversion, IP traffic optical- to-electrical conversion, as well as mixing the IP traffic with CATV signal. D-Node is also known as “Multi-task optical node” for this reason.

The CMTS module integrated inside the JH-DN3416B is from D3-B family, running DOCSIS 3.0. It contains SFP optical port and 1G RJ45 port.

ONU module is optional for D-Node, which is compatible with GE/EPON/GPON.

D-Node contains built-in 1GHz CATV optical receiver and amplifier. With programmable balance and fading control, and optional real-time spectrum analysis module, remote control can be achieved.

JH-DN3416B is a perfect replacement for existing optical node system, which simplifies the network topology and fulfills the Internet requirements for HFC network. With its outstanding network performance and safety features, JH-DN3416B provides the best solution for HFC triple play.

About D3 - B Series

D3-B family is the upgrade version of D3 family, running DOCSIS 3.0 and C-DOCSIS protocol. The D3-B family includes the following  forms of CMTS: compact rack-mount type (1U), high-density type(3U), outdoor type and D-node type.

The benefits of D3-B family over D3 family are listed as follows:

◆ Upgrade from Dual core to Quad core processor for data forwarding;

◆ Upgrade from DDR2 to DDR3 RAM;

◆ Improved power management;

◆ Migrate to Linux operating system;

With these changes, the D3-B family provides faster forwarding capabilities and larger throughput for IP packet (especially smaller size packet or fragment packet are optimized).

All D3-B family products implement CMTS channel bonding technology, providing up to 16 QAM channels with total 1Gbps for DS (downstream), and up to 4 QPSK/QAM channels with total 160 Mbps for US (upstream). The DS can be easily configured to run as either data channel or IPQAM channel. It provides both electrical (RJ45) and optical (SFP, 1.25Gbps) connection for data forwarding. D3-B family also implements layer 3 routing  function,  QoS,  DHCP/TFTP servers, and DHCP relay.

Users have 2 management methods, including CLI withTelnet and  Web interface.

◆ Users can use CLI by login with Telnet (direct connection to the CMTS).

◆ Users can remote login to the CMTS embedded web interface through internet.

D3-B family is capable to run with DOCSIS 3.0/2.0 cable modems, set-top boxes (built-in with modems) and eMTA.

◆ Running DOCSIS 3.0 protocol which is very stable, lower the risk of investment.

◆ All in one box design, simplifies network topology, lowers the cost.

◆ Clients can be Cable Modem or set top boxes, which are cheap and have lots of options.

◆ Pushes the CTMS more close to client side, dramatically lowers noise funneling effect.

◆ High utilization on spectrums.

◆ Remote controls, riches set of management features.

◆ Almost no limits on transmission range.

◆ Low cost per client, with certain scalability.

◆ Low power consumption, no cooling fans needed, designed for outdoor environment.

◆ Can replace the existing optical node without additional equipment needed.
