Etisalat, one of the largest telecommunications companies in the world and the leading operator in the Middle East and Africa, wished to expand an existing CATV head-end in UAE by adding a 700-channel IPTV system. The order to supply the system went to the Chinese telecommunications group Huawei. For the critical system segment from the antenna to the receiver, Huawei relies on products and services of DEV Systemtechnik.

One of the biggest telecom service provider in Vietnam, who had plan to build up a Cable TV network nationwide, including a main head-end in Hanoi plus over 700 Sub head-ends along the country. The Hanoi head-end receives signal from satellite antenna dishes with dual-Pol and IP contribution, and at each Sub head-end delivers both digital and analogue cable TV signal over GPON network.

“RF over Fiber” refers to technology that modulates light with a radio frequency signal for transmission over an optical fiber. All satellite ground stations and teleports must have an effective transmission method for RF signals linking antennas, signal management equipment and wide-ranging equipment centers. Beyond traditional copper or coax, current “state-of-the-art” installations are best served by fiber-optic links.

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.
