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
