Thor's L-band fiber optic transport equipment supports 1, 2, 4, 5, or 6 LNBs over a single fiber. Systems are designed for distributing satellite service to many different locations from a single dish array. This system converts each incoming L-Band feed to an independent optical RF channel using DWDM optics. Modern Satellite TV systems from TV providers have multiple coax feeds from the dish for different polarities. These RF signals feed into a Single Wire Multiswitch, or SWiM, system. All four LNB channels are then combined onto a single fiber output through an internal DWDM coupler. Alternatively, 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 Fiber 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.
