Introduction
The FSU 995 FA is designed to be “the only single fiber
splicer you’ll ever need. ” It handles all basic single fiber
splicing procedures, as well as more complex tasks such as
tapering, attenuator making and erbium splicing. At the heart
of the splicer’s operations is the hot core alignment process,
which individualizes the splicing procedure to fit your fiber
type and climactic conditions in order to offer the lowest
possible splice loss every time. Then, just to make sure, the
FSU 995 FA estimates this splice loss with an extremely
accurate splice loss estimation technique based on mode
coupling theory (micro-bending) and hot image processing.
There are two ways of categorizing the FSU 995 FA’s opera-
tions, and this manual will be organized according to both of
them:
On the one hand, the FSU 995 FA splicing programs can be
divided into two groups: Programs 01 - 10, which are the ten
splicing programs that come pre-defined with the machine,
and Programs 11 - 50 which are the forty editable slots you
have for designing your own splicing programs to suit your
special needs. In this manual, the instructions you will need
to run the pre-defined programs (01 - 10) will be the focus of
the section on “Basic Operation.” After you are familiar with
the FSU basics, you can go on to the second section, “Ad-
vanced Operation,” which outlines the structure of splicing
programs in greater detail, and describes the method for
designing your own.
On the other hand, FSU 995 FA splicing programs (including
the pre-defined ones) can be organized according to six
splicing processes: normal splicing, hot core alignment, small
core alignment, mode field matching, attenuator making, and
pulling or tapering. Whereas, this cross-cut of FSU opera-
tions will be only mentioned briefly in the section on “Basic
Operation”, it will play a large role in “Advanced Operation.”
Generally speaking, even though you will not need to specify
splicing processes when using the pre-defined programs, it is
always helpful to keep splicing process in mind when dis-
cussing any splicing program, since it specifies the steps the
FSU 995 FA goes through when splicing.
