NOTE: It is not mandatory to have an LBO (Lightguide Build-Out) between the optical
interfaces of the 1643 AM 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)).
