Depending on the construction method used the enclosure is
located either underground in a manhole or vault or on the aerial.
A bi-directional OTDR measurement from the CO at 1310/1550 nm
is recommended to qualify the splices (see Figure 3.7).

For the majority of installations, chromatic and polarization mode
dispersion measurements are not required due to the low bit rate
and short span length. However, recently in several countries,
providers have expressed an interest in the ability to deliver 10
Gigabit Ethernet services over FTTH architectures which may
necessitate characterization of the fiber for some service
providers.
