Features • Compact, rugged, lightweight • 150, 500, and 1000 m lengths standard • Available with a variety of connector styles • Compact! Fits easily in OTDR cases or kits Applications • Use to test link loss with an OTDR • For use as OTDR launch cable • For use as OTDR receive cable • Measure insertion loss and reflectance of near- and far-end connections Fiber Rings are often a necessity when testing with an OTDR or Optical Troubleshooter. A launch cable, which connects the OTDR or Optical Troubleshooter to the link under test, reveals the insertion loss and reflectance of the near-end connection. A receive cable, which connects to the far-end of the link, reveals the insertion loss and reflectance of the far-end connection. Launch and receive test cables can range from 150 m to 1 km (or longer) in length. Because very long test cables are impractical to transport and use, AFL offers coiled lengths of 50 μm multimode, 62.5 μm multimode, or single-mode fiber packaged in compact rings. Fiber Rings of 150 m of fiber are ideal for premises fiber network test applications. Fiber Rings of 500 m and 1 km of single-mode fiber are designed for broadband, long haul fiber network test applications. 1 Test & Inspection AFLglobal.com | 800.235.3423 Accessories OTDR Fiber Rings ©2021-2023, AFL, all rights reserved.

FR00-00-2000 Revision AC 2023-05-02 Specifications are subject to change without notice . How to Generate a Baseline Trace Using Fiber Rings • Use the Fiber Ring as a launch cable. Connect the Fiber Ring between your OTDR and the fiber link under test. This will allow you to measure the loss of the near-end connection. • Use the Fiber Ring as a receive cable. Connect the Fiber Ring to the far-end connector of your fiber link under test. This will allow you to measure the loss of the far-end connection. • By using Fiber Rings as both launch and receive cables, as shown in the diagram below, you can measure total insertion loss of the fiber link under test.
