The Soft Pulse Suppressor Bag from EXFO America is an essential tool for modern fiber optic testing, particularly when working with singlemode fiber (9/125 μm) applications. Designed to effectively cover the dead zone of an OTDR (Optical Time Domain Reflectometer), this 150-meter bag ensures precise loss measurement at both the beginning and end connections of the fiber under test. The bag's design not only enhances testing accuracy but also extends the life of the OTDR connector by minimizing the frequency of connections during testing. Compatible with a wide range of connectors, this versatile tool allows for quick connections to most OTDR and patch panel ports. The recommendation of a 150 m length aims to surpass common OTDR dead zone lengths, ensuring reliable performance for technicians. Available in various lengths and with options for both singlemode and multimode fiber types, the Soft Pulse Suppressor Bag caters to diverse field requirements and helps streamline troubleshooting and maintenance tasks in fiber optic networks.
