A test receiver for use with an Optical Time Domain Reflectometer (OTDR), including a first receive fiber having a first attribute, and a second receive fiber having a second attribute different from the first attribute. The attributes may be lengths, marker events, or both. This configuration reduces the number of times an OTDR operator must travel back and forth between cable ends when testing fibers.

Using sets of OTDR receive fibers with different lengths of marker events to verify optical fiber connectivity

A optical time domain reflectometer (OTDR) which sends and receives pulses for multiple frequencies down a fiber under testing (FUT). These frequencies can include frequencies for testing a live FUT and frequencies for testing a dark FUT. The pulses of the various frequencies are sent and received through a single optical connection with the FUT. The number of connections necessary to test the fiber is thus reduced. The OTDR may also include a built in passive optical network (PON) power meter, which measures the power level of the fiber over the same single optical connection.
