GB/T 18311.6-2001 Fibre optic interconnecting devices and passive components--Basic test and measurement procedures--Part 3-6: Examinations and measurements--Return loss (English Version)
This standard specifies the measurement procedure for the return loss of the fiber optic device under test. The reflectance distribution of single-mode optical devices is measured with micrometer-level spatial resolution and high dynamic range by employing low optical coherence interferometry. The return loss of single-mode devices is measured with centimeter-level spatial resolution and high dynamic range by employing the optical frequency domain reflectometry method.
