Description<\/strong><\/p>\n

The EL478 is a state-of-the-art satellite modem optimized for\u00a0high speed IP applications over satellite in compliance with the\u00a0DVB-S2 standard. As a real IP product, this modem performs\u00a0IP processing functions such as packet filtering, routing and\u00a0encapsulation. In order to achieve speeds up to 160 Mbit\/s, only\u00a0the fastest and most bandwidth-efficient encapsulation and\u00a0modulation parameters are supported.<\/p>\n

The EL478 offers a dual auto-switching Gigabit Ethernet\u00a0interface to transmit and receive simultaneously IP packets\u00a0(or Ethernet frames) over satellite. The modem integrates\u00a0seamlessly with terrestrial IP networks and equipment. Incoming\u00a0IP packets can be filtered using VLAN or MAC addresses,\u00a0transmitted transparently (bridging)) or routed to several\u00a0destination addresses using Newtec\u2019s Extended Performance\u00a0(XPE) encapsulation.<\/p>\n

The EL478 is capable of receiving DVB-S2 Multistream, VCM or\u00a0ACM signals and can optionally transmit in VCM mode.\u00a0For maximum bandwidth efficiency, the EL478 can also be used\u00a0in Adaptive Coding and Modulation (ACM) mode, modifying\u00a0the modulation parameters dynamically in function of the link\u00a0conditions. The modem incorporates the renowned FlexACM\u00ae\u00a0technology which fully optimizes the satellite link at optimal\u00a0availability.<\/p>\n

At the output of the modulator, the signal is available on an\u00a0L-band interface. Extended L-band, IF-band as well as BUC power\u00a0supply and reference frequency are available as configuration\u00a0options, providing a compact and cost effective solution.<\/p>\n

When activated, the unique linear and non- linear predistortion\u00a0option Equalink\u2122 provides an additional link margin\u00a0improvement of up to 2dB, truly unleashing the full efficiency of\u00a0higher modulation schemes such as 16 and 32 APSK.<\/p>\n

On the receive side, the EL478 has a dual L-band input. The\u00a0active input is selected by the user and can provide DC power\u00a0and frequency band selection signals compatible with most\u00a0professional and commercial LNBs. An adaptive equalizer\u00a0compensates linear distortion of the transmission channel and\u00a0the integrated Noise & Distortion Estimator (NoDE) tool provides\u00a0an accurate reading of the satellite link margin even in presence\u00a0of non-linear distortion and allows the user to find the optimum\u00a0input back-off setting very easily for 16APSK or 32APSK\u00a0operation, whether or not non-linear predistortion is applied.<\/p>\n

Clean Channel Technology\u2122 is available on the EL478 IP\u00a0modulator as an option. Clean Channel Technology\u2122 further\u00a0improves satellite efficiency by up to 15% compared to the\u00a0current DVB-S2 standard. Newtec\u2019s customers will be able to\u00a0immediately benefit from Clean Channel Technology, as it\u00a0is available as a software field upgrade for existing Newtec\u00a0equipment.<\/p>\n
