Testing your fiber optic loopback component for Attenuation, Bit Error Rate (BER) and OTDR link testing helps you make a high quality product that performs as expected and meets your customers needs perfectly. In this tutorial slideshow with illustrations we cover the background, structure, usage for transceiver and other optical products testing and how to test your optical loopback product.
MTP®/MPO connectors and patchcords are prevalent in fiber networks and their quantities continue to grow as demand for greater capacity and efficiency increases. These multifiber connectors present unique challenges when it comes to assessing their quality and performance. OptoTest is proud to present this complete guide to MTP®/MPO testing. In this guide, you will learn all there is to know about the different test methods, equipment options, troubleshooting, and best maintenance practices to ensure that you have the best testing experience.
This Fiber Optical Insertion Loss tutorial walks you through What insertion loss is. Where it comes from, and explains Single mode, Multimode fibers, and Launch conditions in multimode fiber.
Insertion Loss represents the light lost through connections and through fiber. Light at connections is lost due to lateral misalignments, angular misalignments and MFD mismatches.
Light is lost through fiber due to absorption and scattering. Insertion loss in multimode fibers is extremely dependent on the light filling of the fiber. Launch conditions were standardized to make insertion loss measurements on multimode fiber more reproducible
Multimode fiber Profiles: Step Index vs. Graded. What are the difference, advantages, and applications in Industry. Graded Index vs. Step Index
With any fiber optic measurement instrument or tool used to qualify product, it is mandatory that the tool or instrument be 100% functional and measure per the appropriate specifications when used. A manufacturer’s calibration can perform both functions. Know the risks of internal and self-calibrations and why a full calibration performed by a professional would be needed.
Hybrid cables makes them ideal as a way to link otherwise incompatible infrastructure in existing fiber systems applications. In this tutorial we address the challenge of mating the different connectors of the hybrid cable to the reference cables and detectors used to measure IL and RL.
This article focuses on RL measurement setups that are prone to introducing testing errors. Ways to mitigate these errors are discussed. Some errors are unavoidable; therefore, steps for correcting them out or reducing them are also described here.
A recent update to IEC 61300-3-35 (Fiber optic connector endface visual and automated inspection) is moving forward with the intention to modernize inspection practices and provide more uniform results industrywide. The updates aim to accomplish three things: Link visual inspection results to optical performance Make results more uniform between manual (visual) and automated (software) platforms […]
