- Diagnostic LED indicators provide information on operation status and input signal level.
Signal ORH-2500CW A9812 converts optical signals distributed via passive optical network from the Signal OTH-2500CW A9810 transmitter into electrical RF signals. The electrical signals are the original SAT IF signals (VL–HL–VH–HH) and DVB-T, DAB, FM signals, provided through five RF outputs. The signals from the "virtual LNB" should be fed to a multiswitch or multiswitch system with the required number of outputs. The signals from the multiswitch outputs are then transmitted to the subscriber outputs via coaxial RF cables.
Customers can order any patch cords made to order with required terminating connectors. Please contact your sales assistant.
