  • Applications and Attentions of Optical Fiber V-Groove
    Step 1: Attentions
    1. Don’t crash or scratch the High-precision V-Groove by any hard object in order to avoid damage on V-Groove and then to influence precision of the connection
    2. Wipe the dust in V-Groove by Alcohol Swabsticks every time before use

    Step 2: Prepare Optical Fiber Fracture Sections
    1. Stripping the fibers: Strip coating (about 40mm) of fiber by using Bare Fiber Stripper
    2. Cleaning the fibers: Put some absolute alcohol on absorbent cotton and then wipe the dust on bare fibers
    3. Cleaving the fibers: Cut the fibers by Ruby Knife or Fiber Cutter, left 10mm bare fibers     

    Step 3: Settle Optical Fibers---Aligning the fibers in V-Groove
    1. Put the prepared bare fiber into V-Groove from the left side, make its fracture surface in the middle of the V-Groove
    2. Put down the platen and hold the fiber
    3. Put another prepared bare fiber into V-Groove after dipped some matching fluid
    4. Put ahead to make the two sections connected tightly
    5. Put down Middle Platen and then the Right Platen
