Cable AML has provided a cost effective state-of-the art system to transport video feeds from the US Virgin Island’s Legislature in St Croix to the nearby island of St. Thomas.
The system’s first two hops are implemented with an 18 GHz FM modulated link carrying video and stereo audio from the USVI Government building in Fredricksted (St. Croix) to a relay repeater on St Georges Hill (1.75 miles) and then to a receiver at Blue Mountain (4.45 miles).
To minimize cost and complexity, an on-frequency repeater at St Georges Hill was used to avoid de-modulation, re-modulation and signal processing associated with conventional video repeaters.
At Blue Mountain the video and audio feeds are QPSK-modulated and frequency-multiplexed for transport by a 13 GHz bidirectional broadband link to the nearby island of St. Thomas (a distance of 44 miles).
The receiver at St Thomas recovers the base band video and audio for transmission to the Government facility and the local cable system (Innovative Cable).
The inter-island QPSK link provides a bidirectional backbone with sufficient capacity to allow expansion for transport of more video programming or additional data carriers
