The Fluke Networks' three-jumper test reference cord set contains a duplex multimode cord with scratch-resistant hardened surfaces and polarity indicators. This duplex multimode three-jumper test reference cord is for use with Fluke Networks fiber installation testing devices, such as the DTX CableAnalyzer Series (sold separately). The scratch-resistant hardened surfaces on the connectors enable numerous insertions without degradation in loss performance. The cords indicate polarity with a red boot on the end where light enters and a black boot on the end where light exits for ease of correct usage. They have a 50 μm core diameter, and are available for use with LC, SC, or ST test adapters (sold separately). The test reference cords meet International Organization for Standardization (ISO)/International Electrotechnical Commission (IEC) 14763-3 requirements that test reference cords do not exceed 0.10 dB for multimode at the connectors.


Fluke Networks manufactures tools for network infrastructure installation, testing, certification, and troubleshooting, in copper, fiber, and wireless networks, with its tools widely used by contractors, enterprises, and communication service providers.
