Fiber
Optic MiniCourse: Reading An OTDR Trace
Splice
Splices
are joints between two fibers, usually created by fusing
two fibers together. Splices will have low loss and
minimal reflectance, if any. The loss of a splice is
shown by the lower trace of the fiber after it and the
amount of that drop is the loss of the splice.
Hint: A loss without reflectance can also be caused by
stress on the cable, for example a kink in the cable or
a fiber pinched in a splice tray. Having good
documentation on the cable plant makes it easier to
confirm it's a splice not stress loss.
