Step 1

Take apart ST* Connector by removing dust cover and boot.

[Diagram]

 

Step 2

Slide the flame retardant boot onto .9mm buffered fiber optical cable.

 

Step 3

Strip approx. 1" of the buffer tube from fiber with No Nik Stripper.

Step 4

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.  Set aside carefully.

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. 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 holder.)

  2. Brush the stripped part of the fiber approx. 7/8" (.875") 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 holder until it bottoms out.  [Diagram]

  4. Slide flame retardant boot up the back end of ferrule holder.

  5. 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. 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 holder until it bottoms out.  [Diagram]

  4. Slide flame retardant boot up the back end of ferrule holder.

  5. 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.)

  6. Proceed to Step 6.

Step 6

Cleave fiber on two sides.  Pull straight up.  Carefully dispose of cleaved fiber.

Step 7

Place PVP rubber mat over PVP lapping plate and line with 15, 5, 1, &.3 micron lapping film.

 

Step 8

Add 3 drops of water to each lapping film.  Place connector into ST* polishing puck.

 

Note for Steps 9 thru 12: 

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

 

Step 9

Push down on the spring 1/2 way and do 10 figure 8's, using light even pressure, with 15 micron lapping film.

[Diagram]

 

Step 10

Push down on the spring 1/2 way and do 14 figure 8's, using light even pressure, with 5 micron lapping film.

[Diagram]

 

Step 11

Push down on the spring with 100% pressure and do 10-15 figure 8's using 1 micron lapping film.

[Diagram]

 

Step 12

Push down on the spring with 100% pressure and do 10-15 figure 8's using .3 micron lapping film.

[Diagram]

 

Step 13

For best results, inspect with interferometer.  Pleaser refer to Model 2000 Operators Manual (coming soon to the website) for detailed instructions.  Check apex offset 50um maximum and that fiber end is not polished flat.  Check to see if fiber core and cladding area are free of scratches, chips, and pits.
