A fusion splice
o is a very low loss joint (typically 0.05 dB compared to 0.2
dB for a mechanical splice)
o is very stable because of the homogeneous joint formed by
the fusion process
o has very little reflected light (high return loss) because
the boundary between the two fibres has been removed |
|
o
has a low consumable cost - Although there is a relatively
large capital commitment to acquire the splicing unit,
the cost per splice is negligible. This is because the
only consumables during the fusion splicing process are
cleaning materials and heatshrink splice protectors. The
much higher cost per splice of a mechanical splice means
that after about 500 splices the capital cost of a fusion
splicer has been recovered.
