Product details
The Comtech CDD-564AL packs four independent L-band demodulators into 1RU and combines their received data onto a single 10/100Base-T Ethernet port. It is designed to work with CDM-570/L-IP and CDM-570A/L-IP modems, for example at a hub receiving several remote carriers, and powers LNBs on each input.
Key features
- Four independent L-band demodulators in 1RU
- 950–2250 MHz inputs, each independently configured
- 16 kbps to 10.239 Mbps per demodulator (VersaFEC); TPC to 9.98 Mbps
- LNB power (13/18 VDC) and 10 MHz reference on each input
- Single Ethernet traffic port; Ethernet M&C
