1. SC/FC/LC-APC 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. When using OTDR, the optical fiber cable shall be tested and used together with the optical time domain reflectometer (OTDR) to minimize the impact of OTDR transmission pulse on the measurement uncertainty. There are many different configurations and fiber lengths.
