The soft pulse suppressor bag by EXFO America is specifically designed for use with singlemode fiber (9/125 μm) and offers a length of 150 meters, connecting via LC/APC to LC/APC connectors. This portable solution enhances fiber optic testing capabilities, particularly when utilized alongside an Optical Time Domain Reflectometer (OTDR), to effectively measure loss at both ends of a fiber under test while minimizing the impact of the OTDR's dead zone. With a contiguous fiber design, it enables the most precise connector loss measurements, thereby extending the life of connectors by reducing the frequency of matings. Additionally, a wide array of compatible connectors ensures seamless connections to most OTDR and patch panel ports, making this product a practical tool for technicians aiming to streamline fiber optic testing processes.
