2. Lift up on the adapter’s locking lever. You will hear
a “click” when the latch mechanism disengages.
3. Slide the adapter out of the measurement port.
4. Slide the new adapter on to the connector ferrule in
the measurement port.
5. Push down on the adapter’s locking lever. You will
hear a “click” when the latch mechanism engages.
Connecting Fiber to the Measurement Port
The measurement port is used to connect fiber for Fault
Locate test applications.
To connect fiber to the Measurement Port:
1. Slide the cover on the Measurement Port to the
opened position. See Figure 2-5 on page 2-11.
2. Connect the fiber under test directly to the
measurement port.
CAUTION
!
Never force the connector ferrule or insert it at an
angle into the adapter. Optical fibers are susceptible
to loss from microbends or other stress. Position the
patch cord to minimize mechanical strain.
