1. An apparatus comprising:
a data transmitter, executed by at least one hardware processor, to
transmit data from a first end of a device under test (DUT) towards an optical time-domain reflectometer (OTDR) that is operatively connected to a second opposite end of the DUT;
a data receiver, executed by the at least one hardware processor, to
receive further data that is transmitted by the OTDR from the second opposite end of the DUT towards the first end of the DUT;
an optical attenuator to adjust a level of power of an optical source that transmits the data from the first end of the DUT towards the OTDR; and
a receiver level controller, executed by the at least one hardware processor, to
adjust, based on an amplitude of the further data, a direction of receiving of the further data towards a high amplitude first receiver of the data receiver that is designated to receive high amplitude further data or towards a low amplitude second receiver of the data receiver that is designated to receive low amplitude further data.
