Defining Cables
Defining Subset (or Fiber) Names
You can define the way subsets, such as buffer tubes or fiber ribbons, will
be identified. You can also define your own fiber name or identifier using
the same method.
Each time you launch an acquisition, the subset and fiber names will
change according to a pattern you will have previously defined. These
names are made of a static part (alphanumeric) and a variable part
(numeric). Variable part can be incremented or decremented according to
your specifications, as follows:
You can also deactivate the incrementation to re-use the same subset or
fiber name.
If you select... with incrementation with decrementation
Continuous numbering Variable part increases until it
reaches the highest possible
value with the selected
number of digits (for example,
99 for 2 digits), then restarts
at 1.
Variable part decreases until it
reaches 1, then restarts at the
highest possible value with the
selected number of digits (for
example, 99 for 2 digits).
Numbering by subset
(by groups of 4, 8, ...)
Variable part increases until it
reaches the limit value you
specify, then it will go back
to 1.
As a limit, you can choose from
predefined values or specify
your own. In the latter case,
the value you can enter will
depend on the number of
digits you have specified.
For example, if you select two
digits, you can enter any value
from 01 through 99, inclusively.
Variable part decreases from
the specified limit to 1, then it
will go back to the specified
limit value.
