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.
With any 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. A system inspection and calibration verify that the instrument is functional and that the instrument was and is measuring accurately, while routine maintenance helps to ensure the instrument will continue to function going forward.
While an instrument’s self-calibration or internal calibration is convenient for routine spot checking and verification, it should never replace a full calibration performed by an unbiased and trained professional.
Fiber patch cables, also known as patch cord or jumper cables, are fiber optic cables that are terminated with connectors on both ends. When the connector types on each end are different, the cable is aptly dubbed a HYBRID CABLE. These hybrid cables can serve to link otherwise incompatible infrastructure in existing fiber systems, such as those found in networks or data centers. They can be used to connect newer racks to legacy hardware, in distribution hubs to branch lines from high density panels to the nodes they serve, or to connect between devices from different manufacturers.

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. Continue reading →
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
Make results more uniform between different automated platforms
OptoTest equipment provides the most accurate Return Loss measurements in the industry. In this presentation you will learn more about the elements that make that possible and things to keep in mind to ensure optimal performance.
Changing out reference cables during the insertion loss and return loss testing process to accommodate new DUT types can cause downtime for a manufacturing line and drastically reduce the efficiency of the cable production process.
With single channel DUTs and reference cables, the issue may seem inconsequential. However, in the modern fiber production line every minute counts; any method that can speed up time per test, minimize the time between tests, and prevent downtime are ways to make your cables more profitable.
