On March one of clients complained that part of the multimode ferrules cannot be passed through by multimode bare fibers during the production. After inspection in the production site, it was only found the diameter of the multimode fiber is thicker than the bore diameter of the ferrules.
Usually there are two different sizes for the bore diameter of multimode ferrules: 125.3-126.3 um, 126.5-127.5um. Once the bare fiber is built at the high limit of tolerance, its diameter should be 126.5um, even bigger. In this case, if 125.3-126.3 um ferrule is selected, you can image that they both mismatch. Therefore, when producing the multimode fiber optical connector, JFOPT draw up the rule to choose 126.5-127.5um type to avoid mismatch.
The question at the very beginning of this article, has been solved by replaced by 126.5-127.5um type ferrules.

Definition of passive devices and active devices
Passive device is the component that doesn’t need to work under the external power supply. Including
Fiber optical connector (SC/UPC, FC/APC)
Fiber directional coupler / splitter
Optical add-drop multiplexer (OADM)
Wavelength division multiplexer/ Dense Wavelength division multiplexer (WDM / DWDM)
Fiber optical attenuator
Optical filter (band pass, band stop)
Fiber optical isolators and circulators (polarization-dependent, independent)
Optical polarization controller, fiber delay line (FDL), fiber grating
Active device is the component that needs to work under the external power supply. Including
Semiconductor light source (LD, LED, DFB, QW, SQW, VCSEL)
Semiconductor optical detector (PD, PIN, APD)
Fiber optical laser (OFL, single wavelength and multi wavelength)
Optical amplifier (SOA, EDFA)
Optical wavelength converter (XGM, XPM, FWM)
Optical modulator (EA)
Optical switch / router
