Detailed Description

integrated both common CATV optical receiver and CMTS based on DOCSIS technology.

What is the D-node?
D-node, it is installed on optical node, integrated both common CATV optical receiver and CMTS based on DOCSIS technology. It is an integrated optical-electrical transformation equipment offer both CATV signal optical receiving and IP data transformation function. With both CATV optical port and IP optical port, it connects into HFC and IP backbone network as well as the coaxial distributive network. It works with both cable modem and Two-Way set-top box. It is quite easy to remote monitor and operates.

In fact, D-node is a full service optical node.

The D-node is very flexible to use and there is almost no transmission distance limitation. It could be connected to both Ethernet fiber trunk and EPON. It can be installed on both optical nodes and distributed at the apartment. You may choose either the optical port or electrical port. The D-node will offer full protection of your original investments.

The D-node could meet all requirements of the HFC bandwidth network, it support those service transferring such as analog TV, digital TV, interactive digital TV and broadband internet service. What’s more, It is tailor made for hotel, school, company, hospital and village broadband networking construction, too.

Standardized mature technology to avoid investment risk
Based on standardized technology, the D-node can make full use of your current transmission network and head-end equipment, it compatible with IP backbone, Ethernet and EPON, too. The CATV operator will never puzzle at what kinds of EOC non-standard technology they have to choose thereby protect the original resources to avoid investment risk.

Simplified networking structure to improve stability
The D-node moves the data and TV signals mixing point down to optical node which will greatly simplify network structure. There are also many other advantages such as:
The stability has been improved.
Because of the less user number it covers, the ‘funnel’ will be accordingly smaller, too. The total amount of noise will be reduced which could ensure the internal CMTS run steady at a ‘clean’ network environment
The average subscriber bandwidth will be improved greatly.
With the same bandwidth, the less user it covers, the more bandwidth the house holders will be able to got
It is very simple and convenient to construct and maintain.
lower the network construction cost
For no needs to any traditional optical work station and return optical receiving equipment, the network structure will be simplified and the cost will be reduced, at the same time, it will observably improve the whole performance of the system itself. If you want to keep the original optical receiver and RF Transceiver, you may choose the D-node with electrical port.
Solved the problem between CMTS coverage efficiency and the funnel noise
Due to the expensive equipments of traditional DOCSIS solution, the CMTS is often deployed at the front end plant room.. The larger scale the CMTS covers, the much more efficient its coverage is , the lower cost it will take but, the funnel noise will be larger. It seems that is a certain conflict but the D-node could solve this conflict perfectly.

Advanced management system
With the assorted network management software, you can manage all D-node equipments intensively at the central plant room including the management for both equipments and end users.

Management for equipment: Monitor and control all parameters for its running status, working voltage, power level, temperature and resetting, remote configuration and amendment for the running mode and parameters as well as the fault alarming function.

Management for end user: Including user information, authority controlling, speed limitation settings and billing management, it can also monitor the cable modem running status and parameters.

Alarming: Including alarming from both equipment error and its running status. There will be records on the network management software interface once it suffers any abnormal conditions from voltage, temperature and signal power level. It will also alarm once the cable modem running RF parameter is at the edge and the package loss rate increased rapidly

Internal TV optical receiving & amplifying processing, there are 2 RF out ports with respective amplified module.


lnternal CMTS module, responsible for the transmission of IP data in the cable.


 Compatible and interconnect with both Ethernet and EPON.


Data rate: Downstream 55Mbps,Upstream 60Mbps


Assorted network management software enables many functions such as remote monitor, configuration of all parameters, resetting   and user managements


Support Qos, VLAN, VPN, internal DHCP,TFTP

Optional CATV electrical port (F type socket ) and IP data electrical port9(RJ45)

Based on mature DOCSIS standard, lower investment risk

 Integrated equipment, simplified the network structure and reduced the construction cost

 Use cable modem or set-top box at the head end, cost effective and available in a wide range of equipments


Get over traditional CMTS defects and lowered ‘funnel noise’ interference greatly


Economize frequency source, it needs only one channel for whole network, and enable the cable modems to be online rapidly.


 remote monitoring, powerful management function


there is almost no distance limitation and it can deal with 500 concurrent online users


The coverage cost will be less than USD 4~20 per subscriber (depends on the scale of optical nodes)

Low power consumption & fan less design to ensure the outdoor performance stability
