U.S. Electrodynamics Chooses ViaLite for Ku band Satellite
U.S. Electrodynamics, Inc. (USEI) recently completed the installation of a 4.8m Ku antenna on the AMC-21 Satellite using Vialite RF-over-fiber links between the new antenna and control room. Operated by SES, AMC-21 is a Ku-band satellite providing coverage to all 50 US states, Gulf of Mexico, Central America and the Caribbean. The satellite supports broadcasting services and maritime communications. Sales director at the Brewster Teleport, David Grooms, confirmed that the equipment is now fully operational.
USEI chose ViaLite L-band inter-facility links equipped with wave division multiplexing (WDM). Using separate optical wavelengths, WDM means USEI can transmit multiple signals on a single fiber. Also supplied by ViaLite Communications for this installation, USEI is using UPC7002 automatic up-link power control units from Peak Communications. These units measure the link loss from a satellite beacon and automatically control the uplink power via a number of attenuator channels.
