BM6500 Orion DVB-S/S2 Modulator

2 form factors: 1RU stand-alone system or integrated in 1RU encoder

Orion is a state-of-the-art modulator designed for satellite operations in full compliance with DVB-S, DVB-S2, and DVB-DSNG standards, as well as the latest requirements about Carrier ID defined in ETSI 103 129. It provides operators with best-in-class performance as measured by high SNR value, excellent shoulder levels, and low phase noise, achieving full L-Band (950/2150 MHz) or IF Band (50/180 MHz) coverage with a large, flexible bitrate range of 0.25 to 200 Mbps. The BM6500 offers MPEG-TS input over ASI or IP, signal scrambling (BISS-1, BISS-E), and opportunistic data insertion (MultiProtocol Encapsulation). Control is over IP via an embedded Web server or standard SNMP monitoring and control systems.
