Modern Satellite TV systems such as DirecTV have multiple coax feeds from the dish for different polarities. These RF signals feed into a Single Wire Multiswitch, or SWiM system. Thor F-LB41-DWRX systems provide 4 L-Band RF outputs to drive the multiswitch. These signals are carried over a single fiber from a Thor F-LB41-DWTX transmitter system. These receivers are ideal for large scale systems requiring optical amplification and DWDM. These receivers have a very high sensitivity, allowing them to work under less than ideal link conditions. Functioning at optical power levels down to -12dBm allows F-LB41-DWRX receivers to work even with dirty fiber connectors or poor splices. Typical RF receiver sensitivities are around -7dBm, a sensitivity improvement of 5dB corresponds to almost 15km of Singlemode fiber @1310nm wavelengths. Thor F-LB41 transmitters and receivers can also be used with PLC splitters for multipoint distribution.
