JH-F3416B is the outdoor version CMTS from D3-B family. It is designed to deploy in a harsher environment other than datacenter/headend, such as hanging on the outside wall of the client side building. JH-F3416B has all the core features from D3-B family, plus additional RF ports to support more connection with other optical equipments in the network. JH- F3416B can be connected to GE/EPON/GPON for its upper links. The RF port can have two different options as the applicant vary: 1) DS/US Separate Output Port or 2) 4 Input & 4 Output Port (see ‘application topology’ part in this document). The JH-F3416B case is water proof, and could provide the cooling for the system. Without the need for cooling fans, JH-F3416B is much quieter.
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.
