Patent abstract
The present invention is a passive receive module for use with an OTDR for determining polarity of a cable under test. Only one position of the module connector of the receive module includes a filling and all other positions are occupied with a reflective component with a reflective characteristic distinct from that of the filling. Only one position at the OTDR end of the cable will receive a distinct reflection from all of the other positions. Polarity may be determined from these positions.
