Transmode
Systems AB and Vtesse Networks have completed Trial of amplified CWDM
system using amplifiers from Genoa
Transmode Systems AB, a pioneer of CWDM technology, and the
British carrier Vtesse Networks have successfully performed a field trial
of an amplified CWDM system over 200 Kms. The trial involved linear optical
amplifiers (LOAs) from Genoa and is the first of its kind.
"By working very closely with our customers and component suppliers,
we're, again, first to market with new innovations like this amplified
CWDM system", says Johan Sandell, VP R&D at Transmode. "At Transmode,
everything we do satisfies the requirement of customers in a cost effective
manner. A scalable and amplified CWDM solution will open up new markets
for Transmode and our partners".
In this trial, 4 CWDM channels of Gigabit Ethernet were transmitted over
125 km of fibre by using one LOA as booster. By adding an additional LOA,
the transmission reach could be increased to 200 km.
"Vtesse Networks is implementing a modern, high capacity, low cost
data transmission network in the UK. For many of our transmission requirements,
including mesh and point-to-point systems, CWDM offers the best balance
between performance and cost-effectiveness", says Alan Mitchell,
Chief Technical Officer at Vtesse. "The inclusion of Genoa LOAs into
this CWDM transmission platform allows us to extend span lengths to 100km
and beyond without needing to resort to much more expensive DWDM equipment".
With no sacrifice of performance, amplified CWDM systems allow carriers
like Vtesse to reduce capital and maintenance costs by using less equipment
and, even more significant, reduce their civil engineering costs.
"CWDM has the potential to change the cost structure of the last
mile", says Gerlas van den Hoven of Genoa. "Transmode is taking
advantage of the broadband nature and disruptive economics of LOA to expand
the capability of this emerging network solution."
