State-of-the art satellite communication systems at the highest data rates are operated on the Ka-Band. As transmission quality on Ka-Band frequencies is heavily dependent on weather conditions, suitable system configurations need to be carefully planned and chosen. Ka-Band Site Diversity configurations relying on DWDM RF-over-Fiber transmission systems and redundancy switching units represent best-suited solutions and ensure maximum system reliability and system availability.

The customer is looking for a RF signal management solution for a new IPTV head-end. In order to reach maximum availability the IPTV head-end will receive the satellite signals via two Diversity Antenna Sites (~80km distance between the sites). The RF signal management solution needs to ensure reliable transmission, selection, switching and distribution of the antenna signals.

As BCE moves about 20 Antennas to its Junglinster site in Luxembourg, it embarks on a journey to expand, modernize and enhance its services for its customers. This case study looks at the outdoor-indoor fiber-connection of the successively growing antenna park at Junglinster.

CCTV (China Central Television) is the biggest and most important news media in China. There are 19 antennas, which are used to receive and transmit TV signals, located in 3 positions in the TV station. The distance between any two positions is more than 500meters, so they need transmit L-band signal via optical fiber.

This case study provides an overview of how a large satellite and data communications service provider implemented a cost effective, location diverse antenna installation for Ka-Band satellite data transmissions.
