Step 1

Slide tapered end of .9mm SC boot onto .9mm cable approx. 6". 

[Diagram]

 

Step 2

Slide silver locking piece onto buffered fiber and then slide the spring onto buffered fiber.

[Diagram]

 

Step 3

Measure and mark .750" from the end of the .9mm buffered fiber.  Next, strip the buffered fiber from the mark with No Nik stripper.

 

Step 4

This step is very important.  Clean stripped fiber with isopropyl alcohol soaked lint free cloth.  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.

Step 5 - Gluing the Fiber (Anaerobic and Epoxy)

Anaerobic Instructions

  1. Take Loctite RC680 adhesive with flat end needle and insert into the back end of the connector ferrule holder leaving Teflon guide tube in place. 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. 5/8" (.625") 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 1/4" of the buffer with Loctite 7649 primer. Wait 15 seconds to allow primer to dry.

  3. Thread the fiber through the back end of the ferrule shank through the Teflon guide tube until it bottoms out.  [Diagram]

  4. Proceed to Step 6.

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 back end of ferrule holder leaving Teflon guide tube in place. 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 back end of the ferrule shank through the Teflon guide tube until it bottoms out.  [Diagram]

  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 6.

Step 6

After curing, carefully rotate spring and silver locking piece up the back end of the ferrule holder until spring seats on holder and locking piece is stopped by the spring.  Slide .9mm boot up and slide into place to hold pieces together.

Step 7

Use cleaving tool and 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 fiber, 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 8

Align large flat on silver locking piece so that it is parallel with beveled top of white inner housing.  Insert silver locking piece into white inner housing and rotate so that small flat of silver locking piece can be seen in the white inner housing.

Step 9

Take 15 micron lapping film and roll up and air polish using small circular motions not figure 8 patterns 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 10 & 11:

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

 

Step 10

Now 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.

[Diagram]

 

Step 11

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

[Diagram]

 

Step 12

Then insert ferrule straight up into 100x Inspection Microscope and inspect fiber core.  Click on links below for acceptable and unacceptable polishing outcomes.

[Acceptable]  [Unacceptable]

 

Step 13

Final assembly:  Place SC shroud (cover) with small end over white inner housing as shown in the Diagram.  Make sure that the beveled top side of the white inner housing is lined up with the top of the SC shroud (cover).  Push in together until pieces lock.
