384QAM IPQAM Edge Modulator

上市日期: 2019-06-03

YUK901 is a new generation of high-density IPQAM edge modulator launched by Beijing Yukuan Technology Co., Ltd. It adopts international leading technology and is a universal digital TV platform with high reliability, flexibility and customization.

YUK901 receives multimedia transport streams from video servers or CDN networks through 10 Gigabit IP (10GbE) and Gigabit IP (GbE) network interfaces, extracts the specified TS program stream from it, multiplexes it, debounces the buffer, and up-converts it and other related processing, and output the signal from the RF port to the HFC network after QAM modulation. It is widely used in value-added services such as digital TV broadcasting and interactive on-demand. A single machine can support QAM signal output of 384 frequency points at the same time, and can be flexibly placed in the main front-end, sub-front-end or residential fiber aggregation point.
