Satellite modulator DTH headend

Satellite modulator DTH headend

Outline

The COL5502 DVB-S2 uplink modulator is a high performance modulator developed according to DVB-S2    (EN302307) standard which is the standard of second generation of the European broadband satellite

telecommunication. It adopts advanced framing structure, channel coding and modulation technology, increasing over 50% transmission ability more than DVB-S modulator under the same transmission condition and also  providing a more powerful receiving ability in the same spectral efficiency. It also provides RF 10MHz and 24V/2A DC coupling out. In addition, it is backwards-compatible with DVB-S (EN300421) modulating standard. This COL5502 DVB-S2 modulator supports local and  remote control through NMS software. For field scope, the device can be used for Broadcasting, Interactive  Services, News Gathering and other Broadband satellite applications.
