ote:
It is not mandatory to have an LBO (Lightguide Build-Out) between the optical
interfaces of the 1645 AMC unit and the connected optical cable. However, in the
case of measurements with optical loops and/or connecting power meters an LBO (15
dB) can be required. An LBO can also be necessary to ensure the correct input power
(see chapter 8, section
“Connecting the fiber cables” (p. 8-2)
