Indoor Optical Node (Double Fiber ) TON6800Ec

Overview    TON6800Ec home-type Optical node is designed in accordance with GY / T 194-2003 "cable television system optical station technical requirements and measurement methods" and "SCTE 174-2010 RFoG fiber to the user standard".It can be used in CATV network, digital network and telecommunications network. This device completes the signal transmission of the fiber to the user's home terminal.
   For the traditional HFC architecture, TON6800Ec can enable all-optical network to access home, with the features of flexible configuration, more stable network and so on. It greatly improves user's bandwidth and provide competitive advantages to the operators.
   TON6800Ec’s receiving optical power ranges from -18 to 0dBm. In the range -10 ~ 0dBmAGC, the output level can be up to 90dBuV. Features         ● Compact design, easy to be installed in the Home intelligent terminal box
        ● The use of imported high-quality optical transceiver for photoelectric conversion
        ● The upload RF bandwidth is from 5 to 65/200MHz, can meet the requirements of different CATV system
        ● RF amplifiers are low noise amplifiers for low power reception
        ● Support common HFC set-top boxes, CM and front-end equipment
        ● RF output port is adjustable
        ● Downstream channel has optical AGC function, with the default AGC range from -10 to 0dBm, others are optional;
        ● reverse RFoG (burst), Normal (continuous) two kinds of work mode optional;
        ● perfect safety protection circuit (over-voltage, lightning protection);
        ● Metal shell can be fully shielded, effectively improve the use of complex network environment, anti-interference ability Technical Specifications
