TRITEC FASE II FUSION SPLICER NOW SPLICES
ERBIUM DOPED FIBRE (EDF)
TRITEC Developments' FASE
II fusion splicer can now produce
low loss splices when jointing Fibercore Erbium Doped Amplifier
Fibre to standard singlemode fibre. In response to requests by a
number of customers a special program was developed by TRITEC engineers.
Using this program average splice losses between EDF and standard
singlemode fibre of 0.13dB were achieved.
The FASE II is the first compact fusion
splicer to have a special program developed to splice EDF to standard
singlemode fibre. The FASE II easily matched the performance of
the more expensive 3-axis machines previously used for splicing
these fibres. "Once again the flexibilty of the FASE II's microprocessor
based control has proved its worth" said David Myers, a director
Erbium Doped Fibre or Amplifier Fiber can
be used to boost the signal in long haul fibre cables removing the
need for repeaters. The small core of the Amplifier Fibres means
that special care must be taken when fusion splicing these fibres
to standard singlemode fibres to minimise the mode field mismatch.
The method developed by TRITEC in conjunction
with Fibercore uses repeated short arcs to locally expand the mode
field by diffusion of the dopants. By using this technique, known
as 'Diffusion Splicing', a smooth transition beween the cores is
