Newtec Elevation EL178 160 Mbps High Speed IP Satcom Modulator System

EL178 DVB-S2 IP Satcom Modulator

This product has reached end of life and has been replaced by the Newtec MDM6000.

The EL178 is a state-of-the-art satellite modulator optimized for high speed IP applications over satellite in compliance with the DVB-S2 standard. As a real IP product, this modulator performs IP processing functions such as packet filtering, routing and encapsulation. In order to achieve speeds up to 160 Mbit/s, only the fastest and most bandwidth-efficient encapsulation and modulation parameters are supported.

For point-to-point backbone links, the EL178 can be used in conjunction with the high speed IP satellite demodulator EL978.  In star networks, such as the configuration used in IP trunking applications, the EL178 can be used in conjunction with the high speed modem EL478 in each of the remote sites.

The EL178 offers an auto-switching Gigabit Ethernet interface and integrates seamlessly with terrestrial IP networks and equipment. The incoming IP packets can be filtered using e.g. VLAN or MAC addresses, transmitted transparently (bridging) or routed to several destination addresses using Newtec’s Extended Performance (XPE) Encapsulation.

Multistream

The EL178 supports the DVB-S2 Multistream 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 diff erent receiving sites.

Efficient ACM

For maximum bandwidth efficiency, the EL178 can also be used in Adaptive Coding and Modulation (ACM) mode, modifying the modulation parameters dynamically in function of the link conditions. An embedded FlexACM controller option is available for point-to-point applications, while the optional Base-Band Frame input option allows the EL178 to work with the external Shaper, Encapsulator and FlexACM controller EL860 in point-to multi-point configurations.

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.
