The PSB/SPSB Launch Cable and Pulse Suppressor Box, manufactured by EXFO America, serves as an essential tool in optical time-domain reflectometer (OTDR) testing, effectively addressing the OTDR's dead zone limitation. Designed specifically for applications requiring accurate loss measurement on both the initial and final connections of a fiber under test, this unit ensures reliable performance and precision. Featuring SC/APC narrow key connectors, it guarantees low insertion loss of less than 0.5 dB, making it ideal for single-mode fiber applications. Additionally, with a length of 1000 meters, it provides ample reach in various testing environments, streamlining your fiber diagnostics with ease and accuracy.
