HHTR-1310-LDXX

HHTR-1310-XX is a high performance modular product which is meet for the HFC network to develop the serial function value added service. It also owns such fuctions that the return feedback image, the data, the voice signal as well as the system’s singal and so on.

 Characteristics

• Used in transmitting the HFC network return direction back transmission signal and the network management function signal of the network itself;

• For this back transmission optical transmitting product series, the FP laser or the DFB laser without refrigeration are available to the user; various optional settings of the output optical power are: 0.5mW, 1mW, 2mW, etc.

• As required by the user, the product may be made as a 19 inch 1U standard chassis indoor-type independent integrated machine, or made in a variety of modules as accessories which install to a variety of indoor type optical receivers, outdoor type optical receivers, and optical workstations produced by this company;

• The installation of LCD for indoor independent complete machine, more convenient to know the machine’s working state;

• Adopt the advanced control circuit, ensure the machine’s high performance and stablity;
