Fiber Optic Patch Cord Fluke Test

Fluke Networks recommends using high-quality test cords, reference cords, and inspection tools to accurately test fiber optic patch cords and jumpers.

Using Test Cords and Reference Cords

Fluke fiber optic test cords act as a “window” into the fiber link being tested, so their quality directly affects measurement accuracy. Poor or dirty test cords can lead to inaccurate results, making it essential to use Fluke Networks Test Reference Cords (TRCs) or launch fibers that match the quality of your instruments . TRCs with Metal LC connectors are designed for durability, supporting up to 10,000 insertions and passing Telecordia GR-326-CORE tests, ensuring reliable repeated use .

Testing Patch Cords

To test a fiber optic patch cord, use an optical loss test set (OLTS) like the Fluke CertiFiber Pro. The recommended method is the one-jumper reference method: connect a reference cord to the OLTS, set the reference, then connect the patch cord to the reference cord and the remote unit. This measures the insertion loss between the reference and the patch cord, ensuring compliance with industry standards . Always inspect the end faces of the patch cord for contamination using a microscope or inspection tool like the FI-7000 InspectorPro before testing .

Quick Verification Tools

For simple live/dead detection and polarity checks, the Fluke FiberLert-125 is a pocket-sized, non-contact detector. It can quickly verify fiber activity, polarity, and connectivity for single-mode and multimode UPC/APC patch cords without setup or calibration. The LED and audible tone provide immediate confirmation, reducing the risk of damage and cross-contamination in dense patch panels .

Best Practices

  • Always clean and inspect connectors before testing.
  • Use TRCs or launch fibers to eliminate dead zones in OTDR testing.
  • Follow the one-jumper reference method for accurate insertion loss measurement.
  • Ensure test cords are compatible with your tester and meet IEC/TIA standards .
  • Store test cords in protective cases to maintain performance and longevity . By following these procedures, you can accurately certify fiber optic patch cords, troubleshoot high-loss links, and maintain network reliability using Fluke Networks equipment .
