The Soft Pulse Suppressor Bag from EXFO America is specifically engineered for singlemode fiber applications, featuring a robust design that enhances the efficiency and longevity of optical time-domain reflectometers (OTDR). With a length of 150 meters, this model effectively addresses the OTDR's dead zone, allowing for accurate loss measurements at both the initial and final connections of a fiber under test. Its compatibility with a wide array of connectors ensures seamless integration with most OTDR and patch panel ports, significantly reducing the frequency of mating on the OTDR connector and extending its operational life. Available in various lengths and fiber types, the SPSB-B-150-88-88-A bag is an essential component for professionals engaged in fiber optic splicing, testing, and maintenance.
