The PSB/SPSB Launch Cable and Soft Pulse Suppressor Bag from EXFO America is an essential tool designed for optimal performance in optical time-domain reflectometer (OTDR) testing. With a robust 500-meter length, this unit effectively addresses the OTDR dead zone, allowing for precise loss measurements on both the first and last connections of the fiber being tested. Its portable design enhances field usability, while the singlemode fiber configuration ensures high-quality signal integrity with minimal attenuation at both 1310 nm and 1550 nm wavelengths. Equipped with external patchcords tailored to specific connector types, the soft pulse suppressor bag (SPSB) comes with a range of connector configurations to meet various testing requirements. Overall, this versatile tool not only simplifies the testing process but also ensures accuracy and reliability in fiber optic assessments, making it a valuable addition to any technician's toolkit.
