IRX-111 Indoor Broadband Receiver used in FM multi-channel transmission Cable AML has supplied a very cost-effective broadband FM link for transport of multi-channel TV broadcast signals in a multi-hop configuration involving fiber and microwave. The link involves transporting, via fiber, several CARS-band (13 GHz) FM single-channel signals from a receive location at a distant point to a Cable AML 18 GHz broadband transmitter for transmission to a 21 Km link over water.

Single-channel multi-hop FM video links have been in operation for many years. As operators need to add channels or to transport digital signals, stacking single-channel radios becomes more costly and less effective.

The Cable AML approach bundles the signals to eliminate the need for channel-by-channel demodulation/modulation of the multi-channel signal at each hop, whether fiber or microwave, thereby reducing system complexity and cost.
