FCST221412 OTDR Launch Fiber Cable Box

Product Overview

Measuring an insertion loss of the near-end and / or far-end connection of a fiber optic link with an OTDR requires a launch and / or receives test cable. A launch cable, which connects the OTDR 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 1 km to 2 km (or longer) in length. Because very long test cables are impractical to transport and use, FCST offers coiled lengths of 50 um multimode, 62.5 um multimode, or single-mode fiber packaged in compact rings. Fiber Rings of 1000 m of fiber are ideal for premises fiber network test applications. Fiber Rings of 1 km and 2 km of single-mode fiber are designed for broadband, long-haul fiber network test applications.

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 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.
