U.S. Electrodynamics Chooses
ViaLite for Ku band Satellite
November 12, 2013
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.
