Engineered for precision and reliability, the Soft Pulse Suppressor Bag from EXFO America plays a critical role in optical time-domain reflectometer (OTDR) testing. This device effectively covers the dead zones of an OTDR, facilitating accurate loss measurements on both the initial and final connections of the fiber under examination. Crafted with single-mode fiber featuring a 9/125 µm core surrounded by a durable 3 mm jacket, it ensures optimal performance while maintaining flexibility during testing. The SPSB-B-150-88-91-A model is specifically designed to work seamlessly with various connector types, including SC/APC and SC/UPC configurations. With a length of 150 meters, this launch cable not only enhances measurement capability but also offers low connector insertion and reflectance losses for superior signal integrity. Ideal for professionals in splicing, testing, and fiber optic maintenance, this soft pulse suppressor bag is an indispensable tool for achieving reliable results in fiber-optic installations.
