Step 1

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

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. Set aside carefully.

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.

Step 5 - Gluing the Fiber (Anaerobic and Epoxy)

Anaerobic Instructions

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.)

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.

Thread the fiber through the back end of the ferrule holder until it bottoms out. [Diagram]

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

Proceed to Step 6.

Epoxy Instructions

Mix Epo Tek 353ND epoxy (recommended).
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).
Thread the fiber through the back end of the ferrule holder until it bottoms out. [Diagram]
Slide flame retardant boot up the back end of ferrule holder.
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.)
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

Do 10 figure 8's using light even pressure, with 15 micron lapping film.

[Diagram]

Step 10

Do 14 figure 8's using 5 micron lapping film.

[Diagram]

Step 11

Do 15 figure 8's using 1 micron lapping film.

[Diagram]

Step 12

Do 15 figure 8's using .3 micron lapping film.

[Diagram]

Step 13

Insert ferrule into angled portion of 100x Inspection Microscope. Verify that fiber is radiused and above glass surface.

Step 14

Then insert ferrule straight up into 100x Inspection Microscope and inspect fiber core. It should appear like the picture.

If necessary re-polish by repeating steps 10, 11, & 12.
