Step 1

Slide tapered end of .9mm boot onto buffered fiber approx. 6".

 

Step 2

Strip approx. .800" of the buffer from in front of the fiber with No Nik stripper.

 

Step 3

This step is very important.  Clean stripped fiber with isopropyl alcohol soaked lint free cloth or a dry lint free cloth.  To clean fold cloth in half over fiber and gently squeeze on the fiber and pull it through the cloth.  This will clean the fiber of debris.  Carefully set aside stripped fiber.

Step 4 - Gluing the Fiber (Anaerobic and Epoxy)

Anaerobic Instructions

  1. Take Loctite RC680 adhesive with flat end needle and insert into the knurled end of the silver locking piece of the pre-assembled connector. When it bottoms out, gently squeeze adhesive until a green dot forms in front of the ferrule. Then slowly withdraw adhesive (while maintaining pressure to allow some adhesive to coat the inside of the ferrule and ferrule shank.)

  2. Brush the stripped part of the fiber approx. .675” of the fiber from in front of the buffer (leaving 1/8”(.125”) from the front end of the stripped part of the fiber uncoated) and ¼” of the buffer with Loctite 7649 primer. Wait 15 seconds to allow primer to dry.

  3. Thread the fiber through the knurled end of the silver locking piece of the pre-assembled connector until it bottoms out.

  4. Proceed to Step 5.

Epoxy Instructions

  1. Mix Epo Tek 353ND epoxy (recommended).

  2. After mixing epoxy, fill a syringe with epoxy. Place needle tip over syringe and insert into knurled end of the silver locking piece of the pre-assembled connector. When needle tip bottoms out, inject epoxy until a yellow dot forms in front of the ferrule. Slowly withdraw syringe (while continuing to inject epoxy to allow some epoxy to coat the inside of the ferrule holder).

  3. Thread the fiber through the knurled end of the silver locking piece of the pre-assembled connector until it bottoms out.

  4. Place in fiber optic curing oven at 120° C or more for 3 minutes to accelerate and reduce chemical bond time. Remove from oven and allow to cool. (PVP curing oven recommended.)

  5. Proceed to Step 5

Step 5

Using cleaving tool, lightly score fiber at the point where the fiber comes out of the ferrule tip.  Then pull up on the fiber until it separates from the ferrule.

(Note: Do not snap off, pull directly off.)  (Caution: Cleaved fibers can be very sharp.)

(After cleaving, until the fiber stub is flush with the ferrule, if too much force is applied to the fiber it will easily chip and leave pits or toenails that go into the ferrule.)

 

Step 6

Take 15 micron lapping film and roll up and air polish using small circular motions not figure 8's and do not proceed to the next step until the air polish has only .005" fiber extended above the ferrule face.  Otherwise, there is a chance of snapping the fiber when proceeding to polish.  Blow off with air duster.

 

Note for Steps 7 and 8: 

Be sure to blow off connector and puck after each lapping sequence to prevent contamination scratching of core. 

 

Step 7

Use 5 micron lapping film on top of PVP lapping plate.  Insert connector into polishing puck and do 7 light laps and 8 regular figure 8 patterns wet or dry polishing.  Wet polishing is more forgiving at this stage than dry polishing. Once you master the sensitivity, you may want to just dry polish to reduce the necessity of blowing off ferrule and puck after every lapping stage.

Step 8

Use 1 micron lapping film on top of PVP lapping plate.  Insert connector into polishing puck and do 7 light laps and 8 regular figure 8 patterns wet or dry polishing.

Step 9

Then insert ferrule straight up into 100x inspection microscope and inspect fiber core.  It should appear like Acceptable diagram.
