Description

technical field [0001] The invention belongs to the technical field of optical fiber multi-parameter testing, and more specifically relates to an optical fiber multi-parameter testing device and a control method thereof. Background technique [0002] The test and measurement of optical fiber parameters is a very important link in the optical fiber manufacturing process, and it is also a production process that optical fiber manufacturers must carry out before the optical fiber leaves the factory. Fiber parameters mainly include fiber geometry, cut-off wavelength, power attenuation, macrobending, mode field diameter, etc. According to IEC60793, GB-T15972 and other international and domestic standards, the above parameters have strict definitions and qualification indicators. [0003] At present, the optical fiber parameter testing devices used by domestic large-scale optical fiber manufacturers are mainly imported equipment. Taking the 2300 of PK Company as an example, the en...
