Sell professional fiber optic tester, wavelength 1550nm, dynamic range 24dB, mini otdr fiber optic tester provides users with high precision fiber optic test curve data, users can more intuitively understand and analyze the status and failure of the entire fiber optic link.
Tips: How to choose the wavelength of the fiber optic tester?
The 1550 wavelength test distance is longer, 1550nm is more sensitive to bending than 1310nm fiber, 1550nm has less attenuation per unit length than 1310nm, and 1310nm has higher fusion or splice loss measured than 1550nm. In actual fiber optic cable maintenance work, the two wavelengths are generally tested and compared. For both the positive gain phenomenon and over spacing line, two-way test analysis and calculation are performed to obtain good test conclusions.
