As the technicians who work with fiber opticnetworks for telecommunications or data know, one of the crucial parts of
building a reliable fiber optic network is the quality of the fiber optic
splicing used. In other words, how to
effectively join two fiber optic cables together.
There is a simpler way of connecting optic fiber
cables called connectorization, but splicing is generally a more reliable
method. The reason is that it allows for
connecting fibers which are of two different types, as well as fibers which
need to be restored after they have already been installed or buried and have
been accidentally damaged or severed.
There are special fiber optic tools for
performing this important task, which ensures that the network is
reliable. The two basic types of fiber
optic splicing are the mechanical and fusion methods.
The type of fiber optic splicing differs
according to the fiber optic tools which are used to perform the task of
connecting two optic fiber cables.
The use of fiber optic tools for mechanical
splicing is generally less expensive, as far as the initial investment is
concerned. The tool for performing this
type of fiber connection can cost as low as $1,000, but on the other hand each
single splicing will cost from $12 to $40.
The fiber optic tools which are used for fusion
splicing may cost from $15,000 up to $50,000, but then in the long run it could
be a better investment because a fusion splicing will cost only $0.50-$1.50.
The difference between the methods for fiber
optics splicing is that the mechanical type is a simpler technique which uses
splice to align the two ends of the fibers and thus allow for the light to pass
from one to the other. The problem is
that there is a typical loss of 0.3 dB per mechanical splice.
The fusion splicing is performed with fiber
optic tools which align the fiber ends and actually fuses or welds them
together via heat or electricity. This
creates a permanent connection between fibers and a lower loss of as little as
0.1 dB.
So, while both fiber optic splicing methods are
reliable, one of them offers splicing with a much lower data loss, but requires
a much higher initial investment than the other, so the network owners or maintenance
companies need to calculate their long-term economic and performance goals, as
well as calculate the volumes of work they will be performing before deciding
on which fiber optic tools to purchase for their specific business.
