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.

24 port Terminal box Fiber optic patch panel
Product Description
Fiber optic patch panel terminal box 24 port - 270*137*45
Application
The product can be used on the terminal of the optical cables, different typed and structures, the diameter of which are within 18mm () tray.
Structural features
All property indexes are in accordance with National YD/T814-1996 Standard.
The body makes use of cold rolling steel, and the surface use the technique of dim blowing plastic. Strong adhesive force, artistic and durable
With pigtail output: design of 1-2 cable entrance and fiber exit of 1-24 cores assures flexibility
With adaptor output: design of 1-2 cable entrance and 8 core SC adaptor or 12 core FC/ST adaptor
Cable entrance and fiber exit are sealed with oil resistance NBR to increase the flexibility. Users can choose to prick the entrance and exit.
Overlapping fiber-melting tray and separate insulation earth unit make the disposition of the cores, expanding the capacity and cable-earthen flexible, convenient and safe.
Main technical specification
Weight: 1Kg
Optical fiber winding radius: >=40mm
Extra loss of fiber tray: none
Fiber length left in tray: >=1.6m
Fiber capacity: 24 cores
Working temperature: -40oC ~ +80oC
Lateral pressure-resistance: 500N
Shock-resistance: 750N
Operations
Peel the cable, take off the outer and inner housing, as well as loose contract tube, and wash off the filling grease, leaving 1.1~1.6m fiber and 20~40mm steel core.
Fix the cable-pressing card and the cable, as well as the cable reinforce steel core.
Lead the fiber into the melting and connecting tray, fix heat contract tube and melted
tube to one of the connecting fiber. After melting and connecting the fiber, move heatcontract tube and melted tube and fix the stainless (of quartz) reinforce core stick. Makesure the connecting point is the middle of the housing pipe. Heat the pipe to make thetwo into one. Put the protected joint into the fiber-laying tray. (One tray can lay 12 cores).
Lay the left fiber in the melting and connecting tray evenly, and fix the winding fiber with nylon ties. Use the trays from the bottom up. After all the fiber has been connected, cover the top layer and fix it.
Position it and use the earth wire in accordance with the project plan.
Close the cover. It can be installed on the wall or in horizontal line.
