Newtec Azimuth Series AZ928 High Speed Telecom Satellite Demodulator
Interconnects seamlessly with standard terrestrial SDH / SONET networks via a STM-1 or OC-3 interface
AZ928 Series Satcom Demodulator
This product has reached end of life and has been replaced by the M6100.
Newtec AZ928 is a High Speed Telco Satellite Demodulator that’s used in pair with the High Speed Telco Modulator AZ128 to establish fixed rate 155.52 Mbit/s 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 efficiency. When activated on the modulator, the linear and non- linear pre-distortion option Equalink provides an additional link margin improvement of up to 2dB. An adaptive channel equalizer compensates linear link distortion.
16APSK
In standard configuration the AZ928 operates with a 16APSK modulation scheme. The AZ928 is equipped with a dual L-band input (950-2150 MHz). The standard L-band input has the option to deliver 10 MHz over the L-band inter-facility link to the LNB. Optionally one L-band input can be replaced by an IF (50-180 MHz) input. At the output the signal is converted to an electrical G.703 or an optical single or multi-mode signal.
Key features
• 155 Mbit/s transmission on a 54 or 72 MHz satellite transponder
