FIBER METER
Once the reference measurement is made and you are
ready to begin testing, disconnect the test jumpers from the
receive (RX) ports (not shown). Do not disconnect the test
jumpers from the transmit (TX) ports after the reference has
been set.
After you set the reference, you are ready to make
Autotest measurements. Connect the two handsets, the
test jumpers, and the installed fiberoptic cable as shown
in Figures 5-6 and 5-7.
