Acceptance testing between the CO and the splitter is performed with a bidirectional loss test set
(LTS) to measure insertion loss and ORL. An OTDR may also be used for this testing.

Stage 5: PON distribution cable acceptance test
Prior to performing acceptance testing on the distribution cable,
the technician must ensure that both the connectors and the
patch cords (used for both the test and the network) are in good
working condition. Tests then can be performed with either an
OTDR or a source/power meter/ORL meter combination. If the
technician uses and OTDR, the test should be performed from
either the hub or from the customer premises, or from both if bidirectional
testing is required. If the source/power meter/ORL
meter combination testing option is used, two technicians are
required—one at each end of the link. A VFL also may be used to
check continuity. The results are compared to the design
specifications of the fiber network.
