This N-type IF cable connects the BUC in the ODU to the TX Out of the modem within the IDU. The TX cable works in the
frequency range from 1050 MHz to 1700 MHz and passes a 10 MHz reference signal to the BUC. This protocol and the
cabling is dependent on the specific modem and BUC used for each solution. Kymeta provides an N-type to F-type
adapter to connect this cable to the modem.
3.3 RXcable
This N-type IF cable sends the L-Band (950 MHz to 2150 MHz) signal from the antenna to the modem and provides DC
power for the LNB. It connects the antenna RX OUT port to the modem primary RX IN port (Rx 1). The RX cable works in
the frequency range from 950 MHz to 2150 MHz and provides power for the LNB. Kymeta provides an N-type to F-type
adapter to connect this cable to the modem.
3.4 LNB-to-antenna cable
This cableconnects the LNB to the antenna RX IN port. By default Kymeta provides a 0.3 m (12.0 in.) LMR-195 cable,
with a right-angle N-type connector. The connector is hex and knurl at each end. This cable comes attached to the ODU
mechanicalassembly.
This cableconnects the modem to the I/O box. The Ethernet port is the primary M&C port and is a standard
10/100/1000 Ethernet. It supports multiple protocols for a web server (GUI), ACU-Modem Interface (OpenAMIP™), and
