Multi-fiber mpo connectors are becoming increasingly popular in network infrastructure, primarily due to their ability to provide higher density and faster data transmission. however, as with any component of a network, mpo connectors need to be properly inspected and tested to ensure reliable and accurate connections. in this article, we’ll discuss the best practices for inspecting and testing multi-fiber mpo connectors with inspection microscopes.
Firstly, it’s important to understand the basics of mpo connectors. mpo stands for “multi-fiber push-on” and is a connector format that uses ribbon-type fiber optic cables and supports up to 12 fibers in a single connector. this makes them ideal for high-density applications such as data centers, where space is at a premium.
The most crucial factor in inspecting mpo connectors is cleanliness. any contamination, no matter how small, can negatively impact the performance of the connector and, therefore, the entire network. before inspecting the connector, make sure to clean it thoroughly using a lint-free cloth and an approved cleaning solution.
Once the connector is clean, use an inspection microscope to examine each individual fiber for any defects or damage. a microscope with a magnification range of 200-400x is recommended for most applications. look for any scratches, chips, or other imperfections in the fiber end-face as they can cause light loss and reflection, leading to poor signal quality.
During inspection, it’s important to use a proper technique. for mpo connectors, it’s recommended to use the “push-pull” method. this involves pushing the connector into the microscope and then pulling it back slightly until the end-face is in focus. this technique helps to prevent damage to the connector during inspection.
After inspecting the connector with the microscope, it’s time to perform a test. there are numerous tests available for mpo connectors, including visual inspection, insertion loss, and return loss testing. the most commonly used and recommended is the insertion loss test, which measures the amount of light that is lost as it passes through the connector.
In conclusion, inspecting and testing multi-fiber mpo connectors with inspection microscopes is an essential part of ensuring reliable and accurate connections in network infrastructure. by following the best practices outlined in this article, you can minimize the risk of issues with your mpo connectors and ensure optimal performance for your network.
