1. FC/UPC-FC/UPC optical fiber OTDR transmission cable box test extension line, waterproof and dust-proof, anti pressure and anti drop, excellent sealing, test standard, easy to carry.
2. It is applicable to any OTDR test instrument, cable used for OTDR transmission, optical fiber cable used for OTDR reception, optical fiber line used to eliminate OTDR test blind area, and optical fiber line used for OTDR measurement and connection of near end and far end insertion loss and high reflectivity.
3. Reduce blind spots and improve the accuracy of test results，The optical time domain reflectometer (OTDR) is an essential tool in the process of fiber testing, which utilizes the principle of light scattering to perform fiber loss testing, fiber fault localization, and more. However, optical time domain reflectometry (OTDR) also has blind spots, which can affect the accuracy of testing if appropriate measures are not taken. Using OTDR to test extension cords is a common method to reduce the impact of blind spots.
