Newtec Azimuth AZ128 155 Mbps High Speed Telco Satellite Modulator

Newtec Azimuth AZ128 155 Mbps High Speed Telco Satellite Modulator


Newtec Azimuth AZ128 155 Mbps High Speed Telco Satellite Modulator is specifically designed to be used with the Newtec AZ928 High Speed Telco Demodulator to establish fixed rate 155 Mbps point-to-point satellite links. The equipment interconnects seamlessly with standard terrestrial SDH / SONET networks via a STM-1 or OC-3 interface. The satellite transmission can be operated on 54 MHz or 72 MHz transponders. The modulation is fully compliant with the DVB-S2 standard and provides exceptional power and bandwidth effi ciency. When activated, the linear and non- linear predistortion option Equalink™ provides an additional link margin improvement of up to 2dB. In standard confi guration the AZ128 operates with a 16APSK modulation scheme. At the output of the modulator, the signal is available on an IF-band (50–180 MHz) , L-band (950-1750 MHz) interface. Optionally, it is possible to deliver a 10MHz reference to an external upconverter. A programmable digital equalizer compensates for the external amplitude slope of the cable.
