Warning: Do not touch cleave blade. Any material or solvent that contacts the blade can cause damage.

2.0 Features

The 3M™ VF-45™ Fiber Optic Connector Quick Install Kit is used to field terminate VF-45 multimode and single

mode sockets. The VF-45 sockets are dual optical fiber connectors that are primarily used in fiber-to-the-desk LAN

applications. The duplex fibers are terminated simultaneously using this tool kit.

The VF-45 Fiber Optic Connector Quick Install Kit has the following hardware features and benefits:

a) Carrying case for ease of use with compartments for all required tools.

b) Integrated installation tool comprising:

• Easy scribe and break of fibers to prepare for polishing

• Fiber stub catcher

• Slip resistant polishing base

• Tool pouch storage for all hand tools

• Adhesive backed lapping film for polishing

• Versatile dual illumination microscope with adapters for inspection of:

1) Polishing puck end-face

2) Patch cord plug-fibers

3) Standard ferruled connectors

c) All fiber measurements made with hand tools (no precise measuring)

d) Easy fiber insertion and socket assembly

e) Audible click verifies socket assembly

f) Cleaning with cotton swab

g) Quick assembly of VF-45 socket

h) Angle polishing for low loss, low reflectance connections

i) Replaceable polishing pad

j) Replaceable scribe assembly

k) Replaceable polishing face

Caution: Wear safety glasses during all work operations.

3.0 3M™ VF-45™ Socket

3.1 Contains the following:

a) Housing c) Boot

b) Socket fiber holder (SFH) d) Base

Note: The VF-45 Socket is sold separately.

4.0 Installation

4.1 Position polishing base.

At the patch panel area, place the polishing base on the

patch panel work tray or on a nearby suitable surface. At

the work area outlet, choose a suitable surface. Open the

hinged scribe cover.

Attach a sheet of lapping film to polishing surface of the

station. Removal of the release liner from lapping film

exposes adhesive backing to secure the lapping film to the

polishing surface.

Tech Tip: Before placement of the lapping film, clean the

polishing surface with a lint free wipe moistened

with isopropyl alcohol. Lapping film will last for

about 50 connectors.

Tech Tip: All Isopropyl Alcohol should be reagent grade, 99%

or better. The use of inferior alcohol will adversely

effect interconnect losses. This can be purchased

from a chemical supply house.

Note: Carefully follow safety, health and environmental

information on container label or Material Safety Data

Sheet for isopropyl alcohol being used.

4.2 Position the polishing puck assembly.

Remove the polishing puck assembly from the storage

compartment beneath the polishing pad and place it on

the dovetail on top of the hinged scribe cover.

Open the top of the polishing puck assembly by

unlatching it from the side and opening it by its hinge to

expose the inner cavity.

4.3 Position socket fiber holder in polishing puck

assembly.

Ensure that the cavity is clean of debris and that the face

of the puck is in the up position. Position a socket fiber

holder into the cavity of the polishing puck assembly.

Tech Tip: Do not press on the activation cap of the SFH

during insertion. It should be held by the four

prongs only. (See insert)

4.4 Adjust the jacket stripper so they cut only the outer jacket

and not the Kevlar® strands. Move the stop location

with a small, flat-head screwdriver until the hole size is

correct.

4.5 Remove outer cable sheath.

Cut outer cable jacket at a length of 1 meter (39 in.) and

set tool aside.

Remove the outer sheath by pulling on the end of the

cable jacket, sliding it off the Kevlar® strands and inner

optical fiber buffer tubes. Do not use the tool to slide the

outer jacket off the inner Kevlar strands and buffer tubes.

Discard the outer jacket.

4.6 Remove Kevlar strands.

Use the snips to cut the Kevlar strands flush with the

cable jacket. Discard the strands.

Use a cable tie to strain relief cable in patch panel or

outlet within 2.5 mm (1 in.) of end of sheath.

Note: Do not over tighten the cable tie around the cable jacket.

Pinched fibers may experience optical power loss.

4.7 Even-up the fiber and buffer tube.

If the fiber extends past the buffer tube, trim the

end so the tube and fibers are the same length.

4.8 Position boot.

Place the boot onto the buffer tube, small end

first. Slide the boot along the buffer tube until it

is out of the way.

4.9 Remove buffer tube.

Verify that length guide is pushed flush against

back of tool. Insert the buffer tube into the buffer

tube stripper until it bottoms against the tool.

Squeeze the handles of the tool together and

pull the buffer tube off to expose the two 250 µ

optical fibers.

4.10 Strip the buffer coating from the fibers.

Insert both of the 250 µ fibers into the tube guide

of the dual fiber stripper until the buffer tube

is flush with the outer edge of the tube guide.

Squeeze the handles of the dual fiber stripper

together and pull the fibers out.

Note: Clean the stripper blades with the brush end of

the cleaning tool when needed. See “Dual Fiber

Stripper Maintenance” section.

4.11 Clean the fibers.

Moisten a section of a lint-free wipe with isopropyl

alcohol. Wipe the residue from the fibers using the

moistened lint-free wipe until the fibers squeak.

Tech Tip: All Isopropyl Alcohol should be reagent grade, 99%

or better. The use of inferior alcohol will adversely

effect interconnect losses. This can be purchased

from a chemical supply house.

Caution: Care should be used when handling fibers so as not

to break them, or to handle them in such a way that

they could penetrate your skin.

Note: Carefully follow safety, health and environmental

information given on container label or Material Safety

Data Sheet for isopropyl alcohol being used.

4.12 Thread the fibers into the holder.

Spread the fibers slightly apart between your fingers

to feed them into the socket fiber holder. Refer to

label inside polishing puck for duplex A-B crossover

orientation. (e.g., patch panel A-to-B, outlet B-to-A).

Every link must cross (i.e. patch panel to patch panel).

Tech Tip: Make sure that the face of the polishing puck

assembly is in the closed position before the fibers

are inserted.
