High-speed digital radio-relay stations of Contact series

High-speed digital radio-relay stations of Contact series (DRRS) work in frequency range 7...11,7GHz and are intended for organizing one radio group of single- and multispan radio relay lines with bandwidth of Ethernet traffic up to 155Mbps.

DRRS series "Contact-xxM.310Mxxx" is intended for Ethernet traffic transmission up to 310 Mbps (QAM64, frequency band is 54 MHz; the price is 9000$). The technical features are identical to the DRRS 155M1 features. The difference is only in traffic speed - 310 Mbps, in emission frequency band - 54 MHz and in sensitivity: -61 dBm.

- "Contact-11.100M1 ETH" for transmission of Ethernet traffic 100 Mbps;
- "Contact-11M.1001 3*ASI, ETH" for transmission of three digital streams TS - DVB up to 31,5 Mbps each and Ethernet traffic with the    speed 3 Mbps;
- "Contact-11.1551 ETH" for transmission of Ethernet traffic 155 Mbps;
- "Contact-11M.1551 3*ASI, ETH" for transmission of three digital streams TS - DVB up to 45 Mbps each and Ethernet traffic with the    speed 3 Mbps;
- "Contact-11.3101 ETH" for transmission of Ethernet traffic 310 Mbps.
