Digital Satellite Modems

The CDD-562L is a companion product to the CDD-564L and CDD-564. The CDD-562L receives two, independent L-Band channels and combines them into a single, network-ready, 10/100BaseT Ethernet port. The two demodulators, integral router and IP Module are housed in a 1RU chassis. These products are designed to operate with Comtech EF Data’s IP-enabled product line, including modems and performance enhancement proxies.

The CDD-564 and CDD-564L are the first integrated quad IP demodulators, capable of receiving 4 independent 70/140 MHz or L-Band channels respectively and combining the output into a single 10/100BaseT Ethernet port for transmission onto the LAN. The 4 demodulators and the integrated IP Module are housed in a 1RU chassis. CDD-564/L is designed to operate with Comtech EF Data’s IP-enabled products including modems and Performance Enhancement Proxies.
