Cable headend DVB-T2 RF modulator COL5601

COL5601  Cable headend DVB-T2 RF modulator 

Outline

COL5601 DVB-T2 modulator is our new product developed complying with the DVB-T2 standard. With its 

advanced modulating technology, this modulator can effectively make use of the ground spectrum resources 

and make it possible to provide reliable signals for fixed, mobile and portable devices. Compared with DVB-T, 

the channel capacity is increased by 30% under the similar carrier to noise ratio (CNR) threshold. COL5601

DVB-T2 modulator also supports single-PLP and multi-PLP (option) to receive T2-MI from DVB-T2 gateway 

through its ASI and IP port. (This function is also option) Moreover,this device can be upgraded and controlled

through network system, which allows it to be widely used in setting up digital broadcasting network and 

provide good signals for scientific laboratory and DVB-T2 STB.
