Radio frequency over fiber
optic links are a great solution for moving high
frequency analog signals over a long
distance, but solutions need expert planning,
design and installation to get the best
performance. When SES needed
a long distance link from the European Space
Agency Redu station in Belgium to the SES site
in Luxembourg,
ViaLite’s experience in the market and long
distance link solutions made the company a
winning choice for the
project.
SES required a long
distance link system which
provided a high dynamic range in bandwidth and
could be controlled remotely by SES operations
staff. The distance
between the SES site and the Redu station is
over 120 km and crosses over the border between
Belgium and
Luxembourg.
ViaLite’s DWDM long
distance link system was the chosen solution;
installed at the two sites, with a third site at
the
border required for signal amplification and
interconnect between the two countries. The
technology used is capable
of connecting sites that can be hundreds of
kilometers apart and has full bandwidth
capability from 700 MHz
through to 2450 MHz. As part of the system,
optical amplifiers, optical switches,
multiplexers and de-multiplexers
were supplied, as well as dispersion
compensation module and delay lines; provided to
help with optimizing and
balancing.
Steve Jones, a Senior
Systems Engineer at SES, commented on the
results: “We are over the moon, we couldn’t ask
for more. ViaLite were extremely supportive and
most importantly, it works!”
Amair Khan, from ViaLite,
said: “It was a great project to work on. It’s
rare to have the opportunity to deploy a fiber
link across country borders. The solution we
provided was adaptable in order to compensate
for optical losses
throughout the fiber system.”
