Comtech CDM-710G High-Speed Satellite Modem
The CDM-710G High-Speed Satellite Modem provides transmission of data using the same powerful DVB-S2 techniques developed for video delivery in Digital Video Broadcast (DVB) applications. It operates over satellite links with programmable symbol / data rates up to 45 Msps.
The modulation types supported include DVB-S2 QPSK, 8-PSK, 16-APSK and 32-APSK. Constant Coding and Modulation (CCM) operation with a single input stream is provided for 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-10-1 with G.703 E3/T3/STS-1, CDI-60 HSSI and CDI-70 Gigabit Ethernet.
