Product Description
Bidirectional Optical Node

Description
With modular design and bus connection, TW2 optical node can provide unprecedented specification and flexibility for operators. It has place for two power supply modules and five standard modules, including two optical receivers, two optical transmitters and one network management module, it also can be combined in other mode. With "Virtual Headend" technology, it can be equipped with other modules according to the development of network. It can narrow to 1/2 of the initial covered subscribers, so it will not waste the initial investment and upgrade seamlessly, also it can reduce the breaking time of maintenance to the lowest.
The ClassI or ClassII transponder module, which is available for optical node, complies to Hms standard and work with ACE network management system, so it supports the developing HFC network. TW2 optical node supports RFOG technology. To suppress the return noise in every return path, user can choose tri-status gate or RFOG spare parts.

Features
1. 47~870/1000MHz working bandwidth
2. Modular design, it can be configured with one network management module, two forward optical receiver modules, two return transmitter modules and two power supply modules.
3. Four separate amplifier boxes, four output ports
4. Forward and return path allow multiple configuration by intelligent options
5. Optical AGC
6. Intelligent design, it can automatically recognize the type, quantity and installation place of the modules, as well as the operation mode of the node. It can be remote controlled or configure module and plug-in by WEB
7. Multiple-bandwidth output amplifier boxes with separate frame structure to improve the flexibility and reduce the maintenance cost
8. ClassI or ClassII transponder module available
9. Return path can support APC, RFOG, tri-status gate and intrusion switch
10. Dual backup power supply available
11. Separate power port, 15A bypass current
