The Newtec Elevation Series EL978 is a state-of-the-art satellite demodulator optimized for the reception of high speed IP applications over satellite in full compliance with the DVB-S2 standard.
In order to achieve
speeds up to 160 Mbit/s, only the fastest and most bandwidth efficient encapsulation and modulation parameters are
The EL978 can be used in high speed Point-to-Point backbone
links or in star IP trunking configurations, in conjunction with
the high speed satellite IP modulator EL178 at the uplink side.
The EL978 offers an auto-switching Giga-bit Ethernet interface
and integrates seamlessly with terrestrial IP networks and
equipment. The data received from the satellite must be
encapsulated with Newtec’s XPE (Extended Performance
Encapsulation) protocol, a highly efficient system to transmit IP
data in DVB-S2.
For maximum bandwidth efficiency, the optional FlexACM client
allows the EL978 to provide feedback on the link condition to
an FlexACM controller located at the uplink site, so that the
modulation parameters can be adapted automatically and
The EL978 supports the DVB-S2 Multi-stream mode, allowing
the IP traffic to be divided in several streams, each stream being
transmitted with its own identifier. When the Variable Coding
and Modulation (VCM) mode is activated, each stream can be
transmitted with its own set of modulation parameters, further
optimizing the transmission efficiency when different streams
are intended to different types of receiving sites.
The EL978 has a dual L-band input (950-2150 MHz). 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 find the optimum
input back-off setting very easily for 16APSK or 32APSK
operation, whether or not non-linear predistortion is applied.
