Wire & Cable ASIA – July/August 2013
Fujikura Europe, a manufacturer of
fibre optic cables and equipment,
showcased the first commercially
available glass and processing system,
the LZM-100 LAZERMaster, in Munich
in May.
Exclusively developed and
manufactured by Fujikura’s global
research and development team, the
LZM-100 uses a CO2 laser heat source
to perform splicing, adiabatic tapering,
end-capping and other glass-shaping
operations.
It is also involved with fibre laser
component development; such as for
pump combiners and mode-field
adaptors.
CO2 laser heating has been designed
to enable cleaner splicing with no
contamination, electrode or filament
maintenance and instability is
eliminated.
A typical CO2 laser has an output
power fluctuation of ±5 per cent that
produces inconsistent splicing results
and may cause irregularity and ripple
in a taper profile.
The LZM-100 patent-pending laser
power stability feature allows stable
laser output, enabling highly
repeatable processes and very smooth
taper profiles.
With an integrated closed-loop
feedback system and real-time
measurement function, both splice
loss and peak-to-peak taper ripple are
greatly reduced.
“The LAZERMasterTM is a unique
customised CO2 laser splicing and
glass processing system that will help
decrease costs by improving
performance and productivity,” said
Roy Higgins, deputy managing
director.
“The specialised CO2 laser brings
many advantages to the market such
as clean and stabilised CO2 laser heat
source and advanced feedback control
techniques.
“With a significant trend in the industry
towards the increased use of fibre
lasers and high power delivery
systems, the LZM-100 can be adopted
into the technically advanced markets
such as the fibre laser industry,
bio-medical applications, military and
defence and more.”
The LZM-100 uses a Warm Tapering
Imaging (WTI) monitoring system for
precise control of heating power.
The WTI brightness level is captured in
real time during the tapering and the
value is used to adjust the CO2 laser
output power to a level appropriate for
the decreasing mass of a fibre as it is
tapered to a smaller diameter.
The LAZERMasterTM has specially
designed onboard firmware enabling
operations to be performed
automatically, manually or remotely
through a PC.
It has large diameter fibre splicing
capabilities up to 2.3mm and long
tapering capabilities up to 150mm, and
beam size and shape can be
customised to meet specific
requirements to enable it to be used
for fused glass component
development and mass scale
production.
