Self-Supporting Cable Placement
This method involves hanging the distribution cable in one pass. The reel is typically loaded
onto an arbor on the rear of a truck. The technician starts at the Central Office (CO) end of the
run, feeds out the specified amount of slack, aligns the first PAM, and then progresses towards
the other end of the run. See

Tether Handling
The tethers are connectorized or non-connectorized. Tethers are taped to the cable to protect and
manage the tether during reel loading and cable placement. For aerial placements, the taped
tether requires the line or splice technician to remove the tape to align/place the terminal. For
underground placements, a tether release mechanism is built into the tether attachment to assist
in pulling the tether into the hand-hole or pedestal.

Testing
A Loop Back plug
end of the distribution cable. Loop back plugs are also available factory installed into any other
MFC jacks of specific tethers. Field technicians can then use a light source or OTDR to check
fiber continuity or signal characteristics of the fibers connected through the loop back plug.
