4x L-Band DWDM OTx For Satellite TV

4 Satellite TV Polarities over single fiber via DWDM: EDFA Compatible 

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.  The Thor F-LB41 systems are designed for distributing satellite service such as DirecTV to many different locations from a single dish array.  This system converts each incoming L-Band feed to an independent optical RF channel using a DWDM optics.  All four LNB channels are then combined onto a single fiber output through an internal DWDM coupler.  Alternately, individual signal outputs can also be used for transport over 4 fibers.  The combined DWDM optical output can then be run into an EDFA optical amplifier to boost the signal to high power levels.  Once amplified it can be split through PLC couplers for fan type distribution.  Thor F-LB systems are an effective solution for eliminating satellite antennas in residential developments.  This platform can reduce a satellite farm down to a single dish and LNB.  When used with EDFA amplifiers, a single Thor F-LB41 transmitter can deliver satellite TV service to over 1000 homes.
