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, 8PSK, 16-QAM, 16APSK and 32APSK. 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. With an ASI interface and either a 70/140 MHz or L-Band IF, the CDM-710 is equipped with the configurations most frequentlycrequested by users. This is ideal for video or data transmission formats that take advantage of the frame structures developed for digital video applications. With the Gigabit Ethernet, new opportunities are opened.
