The CDM-710 Broadcast Satellite Modem is intended for operation in Digital Video Broadcast (DVB) and generic data transmission applications. It operates over satellite links and provides programmable symbol / data rates up to 45 Msps in DVB-S21, DVB-S and DVB-DSNG modes. The modulation types supported include QPSK, 8-PSK, 16-QAM, 16-APSK and 32-APSK. Constant Coding and Modulation (CCM) operation with a single input stream is provided for DVB-S2 operation. The unit is available in modulator only, demodulator only, and modem configurations. The terrestrial data interfaces are field-removable to allow swap out of interface types. The data interfaces include the CDI-40 with ASI, CDI-70 Gigabit Ethernet and CDI-60 HSSI. DVB-S2 offers new opportunities for broadcast applications. With a broad range of modulation and coding formats, it permits the user to tailor a link for the available bandwidth and power to optimize link performance. Whether a link is for Direct-to-Home (DTH) or Digital Satellite News Gathering (DSNG), Contribution or Distribution, there is a format available to suit each application.
