SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
1.1.2 EL970 IP Satellite Demodulator
The EL970 is a state-of-the-art satellite demodulator designed for IP applications
over satellite in full compliance with the DVB-S and DVB-S2 standards. The EL970
connects directly to terrestrial IP network infrastructures via a single auto-switching
Gigabit Ethernet interface. The receiver demodulates, restores and filters the data
received from the satellite at rates of up to 133 Mbit/sec.
The EL970 comes with several hardware and software options and can be used in
Point-to-Point links as well as in Point- to-Multi Point networks. It is compatible
with a wide range of encapsulation protocols: data piping, MPE, ULE and Newtec’s
proprietary XPE (Extended Performance Encapsulation). The EL970 is capable of
receiving DVB-S2 Multi- Stream, VCM and ACM streams, and is able to
demodulate higher modulation schemes such as 16APSK and 32 APSK.
For maximum bandwidth efficiency, the optional FlexACM client allows the EL970
to provide feedback on the link condition to a FlexACM controller located at the
uplink site, so that the modulation parameters can be adapted automatically and
dynamically.
The EL970 has a dual L-band input. The active input is selected by the user and
can provide DC power and frequency band selection signals compatible with most
professional and commercial LNBs. Optionally, one L-band input can be replaced
by an IF input.
The integrated Noise & Distortion Estimator tool provides an accurate reading of
the satellite link margin even in presence of non-linear distortion and allows the
user to easily find the optimum input back-off setting for 16APSK or 32APSK
operation, whether or not non-linear predistortion is applied.
Combining new innovative features and advanced data encapsulations protocols
with DVB-S2 technology, the EL970 ensures the highest bandwidth efficiency
available on the market.
The following list is an overview of the key features:
• DVB-S2 and
DVB-DSNG/S compliant;
• QPSK, 8PSK, 16APSK and 32APSK;
• XPE, ULE, MPE, GSE, data piping encapsulation;
• Data rates up to 133 Mbit/s;
• Adaptive equalizer;
• multi-stream and VCM support;
• Noise & Distortion Estimator (NoDE) tool;
• Optional FlexACM client (FlexACM);
• Optional 10 MHz reference input/output
• Featured-based pricing and software upgradability.
