technician then measures the fiber at the CO and one output of the
tested splitter at the hub.Without disconnecting the test equipment
at the CO, the technician must move the test equipment to a
different output of the same splitter and perform another test. This
process is continued until the entire splitter is tested.
Technicians may opt to test only one or a few outputs rather than
testing all of the outputs of the splitter. Test equipment is
connected at the CO to the fiber which is linked to the next splitter.
Then, the test equipment is connected at the hub to this splitter
and testing is performed. This process is continued until all
splitters are tested.
In all cases, measurement results should be compared to the
specific requirements for loss distance, and ORL as specified in the
design of the fiber cable network. Test results are compared to
these requirements and corrective action is taken when needed
by testing with the OTDR for the same fiber. Each result is recorded
in the unit and also on a customer network database for
maintenance purposes. Both manual and automated testing
options are available.
