Newtec Elevation Series EL478 High Speed IP Satellite Modem
Includes Auto-switching Gigabit Ethernet interface to transmit and receive simultaneous IP packets
Newtec EL478 High Speed IP Satellite Modem
This product has reached end of life and has been replaced by the Newtec MDM6000.
The Newtec EL478 is a state-of-the-art satellite modem optimized for high speed IP applications over satellite in compliance with the DVB-S2 standard. As a real IP product, this modem performs IP processing functions such as packet filtering, routing and encapsulation. In order to achieve speeds up to 160 Mbps, only the fastest and most bandwidth-efficient encapsulation and modulation parameters are supported.
The popular Newtec Elevation Series EL478 offers an auto-switching Gigabit Ethernet interface to transmit and receive simultaneously IP packets (or Ethernet frames) over satellite. The modem integrates seamlessly with terrestrial IP networks and equipment. Incoming IP packets can be filtered using VLAN or MAC addresses, transmitted transparently (bridging)) or routed to several destination addresses using Newtec Extended Performance (XPE) encapsulation.
DVB
The EL478 is capable of receiving DVB-S2 Multi-stream, VCM or ACM signals and can optionally transmit in VCM mode. For maximum bandwidth efficiency an ease of operation, the EL 478 has an embedded point-to-point FlexACM controller option that allows to automatically and dynamically adapt it’s uplink modulation parameters in function of the link condition.
The FlexACM client option provides the modulator/modem on the other side of the satellite link with feedback on the conditions of the received signal. When two modems both equipped with the FlexACM controller and client options are connected to each other, they negotiate automatically and dynamically their configuration parameters in both directions.
L-Band
At the output of the modulator, the signal is available on an L-band interface. Extended L-band, IF-band as well as BUC power supply and reference frequency are available as configuration options, providing a compact and cost effective solution.
When activated, the unique linear and non- linear pre-distortion option Equalink provides an additional link margin improvement of up to 2dB, truly unleashing the full efficiency of higher modulation schemes such as 16 and 32 APSK.
Dual Inputs
On the receive side, the EL-478 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. An adaptive equalizer compensates linear distortion of the transmission channel and the integrated Noise & Distortion Estimator (NoDE) 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 pre-distortion is applied .
