Product Introduction
MKQR-633 two-way data modulator has built-in dual—port date modulator and high anti-interference
bit stream module.
It adopts advanced digital signal processing technology, fully in line with DVB-S standards.
Data modulator, in the handling of data flow, adopts random processing of energy diffusion,
RS coding, convolution intertwined, and contract convolutional code, modulation before forming
the base-band processing, ect., to ensure that the data transmission performance. With perfect
and advanced error correcting capability, compared with common PDH/SDH microwave and network
bridge, it has higher demodulation threshold.
The stream receiving port offers high efficient code rate and cache controlling, having a high
reliability, good stability and high ant-interference, integrating independent and exclusive stream
receiving module inside the 1 U chassis. It can overcome problem such as crash, and so on.
