Optical network in
the Amazon
TIM Brasil has selected and deployed
100G optical networking equipment
supplied by Xtera Communications Inc
for a long-haul transmission infrastructure
to connect three Amazon states in the
northern part of Brazil.
Xtera’s Nu-Wave Optima TM 100G
optical networking platform is providing
the high capacity and long-span
capabilities necessary to expand reach
through the Amazon region.
This new optical backbone network
was built using the tower transmission
lines and power substations of the LT
Amazon consortium to transport the
TIM Brasil cables across 27 cities in the
states of Amazonas, Pará and Amapá.
Due to the challenging geography
of this environment, five out of the 14
spans that make up this infrastructure
exceed 200km between sites where
active optical equipment is positioned.
The longest of these spans is almost
260km.
Xtera’s Nu-Wave Optima platform is
a modular optical transport system,
designed to lower the total cost
of ownership by using a common,
integrated set of modules for long-haul,
unrepeatered and regional repeatered
submarine applications.
For terrestrial backbone networks, the
Nu-Wave Optima equipment delivers a
line capacity of 15 Tbit/s over 3,000km
with no intermediate regeneration. For
unrepeatered applications, a capacity
of 8 x 100G was recently transmitted
over a 481km cable.
