Traceable fiber optic cable assembly with indication of polarity

A method for determining polarity of a traceable fiber optic cable assembly, comprising:

• transmitting an optical tracing signal into a first duplex connector at a first end of a traceable fiber optic cable of a traceable fiber optic cable assembly, the optical tracing signal transmitted to at least one of:
• (i) a first tracing end of a tracing optical fiber in a first tracing opening of a first housing of the first duplex connector for propagation through the tracing optical fiber to a second tracing end of the tracing optical fiber in a second duplex connector at a second end of the traceable fiber optic cable, the first tracing opening in a preconfigured orientation relative to a first transmit simplex connector of the first duplex connector;
• and
• (ii) a first unfilled opening of the first housing of the first duplex connector;
• and
• determining an orientation of the first duplex connector corresponding to a first polarity state of the traceable fiber optic cable assembly by visually observing whether the optical tracing signal emits from a second housing of the second duplex connector.

A traceable fiber optic cable assembly, comprising:

• a traceable fiber optic cable comprising at least one data transmission element and a tracing optical fiber comprising a first tracing end and a second tracing end;
• a first transmit connector at a first end of the traceable fiber optic cable;
• a first receive connector at the first end of the traceable fiber optic cable;
• a second transmit connector at a second end of the traceable fiber optic cable;
• and
• a second receive connector at the second end of the traceable fiber optic cable;
• wherein the first tracing end of the tracing optical fiber is proximate the first transmit connector at the first end of the traceable fiber optic cable and the second tracing end of the tracing optical fiber is proximate the second receive connector at the second end of the traceable fiber optic cable;
• and
• wherein the first tracing optical fiber is configured to receive a optical tracing signal at the first tracing end for propagation of the optical tracing signal through the tracing optical fiber to the second tracing end of the tracing optical fiber to indicate a polarity orientation of the first transmit connector and the first receive connector.
