Xtend Saga EMS – Encapsulator Modulator System

The Forsway-branded Xtend Saga EMS product is a high-performance DVB-S2 Modulator and IP Encapsulator featuring ACM (adaptive coding and modulation) and MPE (Multiprotocol Encapsulation) support, fully integrated with the Forsway Xtend complete satellite extension ecosystem.

The Xtend Saga EMS modulators and encapsulators provide efficient transmission of satellite data. Xtend Saga EMS ensures adaptation of IP data provided by the Forsway Mímir Gateway for transmission-over-satellite and is a key component of the Forsway Xtend Hub. The Forsway EMS system currently supports DVB-S2/ACM with MPE encapsulation, while hardware provided by the EMS also supports these features.
