1. INTRODUCTION

The MT–RJ jack kits listed in Figure 1 are designed to

terminate 250–

m coated optical fiber. The jack kits

must be used with only the optical fiber size given in

Figure 1. Read these instructions thoroughly before

assembling the jack kits.

These jack kits cannot be used with build-up

tubes, loose tube fiber, easy-strip fiber, fan-out

kits, or breakout kits.

Dimensions in this instruction sheet are in metric

units [with U.S. customary units in brackets].

Figures are not drawn to scale.

The jacks fit into adapter plates or patch panels for

use in a rack– or wall–mount enclosures or

enclosures having an adapter plate or patch panel.

The jacks can also be installed in wall outlets for use

in wall boxes using Parallel Dress Clip 1374206–1

(simplex) or 1374205–1 (duplex) shown in Figure 1.

For available adapter plates, patch panels,

enclosures, and wall outlets, and installation

instructions, refer to 408-8844.

Reasons for reissue of this instruction sheet are

provided in Section 6, REVISION SUMMARY.

2. DESCRIPTION

(See Figure 1)

Each jack kit contains six MT–RJ jack module

assemblies (each with protective cover), an icon

wheel, 250–

m fiber guide (beige), and two actuation

keys.

The jack kits are shipped with the protective

covers installed onto the jacks. Keep protective

covers in place until ready for connection.

Each jack has two channels designated (on the top of

the jack) with “A” and “B.”

3. ASSEMBLY PROCEDURE

ALWAYS wear eye protection when working with

optical fibers. NEVER look into the end of

terminated or unterminated fibers. Laser radiation

is invisible but can damage eye tissue. NEVER

eat, drink, or smoke when working with fibers.

This could lead to ingestion of glass particles.

During assembly, keep components and tools as

clean as possible to avoid contamination in the

optical interface.

3.2. Preparation

A. Stripping the Cable

IMPORTANT

For correct system polarity, Channel “A”

must be connected to Channel “B” and Channel “B”

must be connected to Channel “A” on any cable run

or cable assembly (including fiber optic equipment).

Refer to Figure 2.

1. Using the fiber optic combination strip tool, strip

the fiber to 31 to 33 mm [1.22 to 1.30 in.].

2. Clean the stripped portion of the fiber with an

alcohol fiber wipe or lint–free tissue moistened with

isopropyl alcohol greater than 91% (99% preferred)

to remove the fiber coating residue. DO NOT touch

the stripped portion of the fiber after cleaning.

B. Cleaving the Fiber

Fibers must be terminated as soon as the

cleaving and inspection process is complete;

otherwise, damage to the fibers could result.

1. Open the fiber clamp of the fiber optic cleaver.

Press the button, and slide the carriage back

(toward the fiber clamp). Then move the fiber slide

back until it stops.

2. Place the stripped fiber into the slot so that the

end of the buffer is at the 4–mm marking. See

Figure 3, Detail A.

3. While applying pressure on the buffer, carefully

slide the fiber slide forward (toward the carriage)

until it stops. See Figure 3, Detail B.

4. Gently close the fiber clamp, and slide the

carriage forward. DO NOT touch the button while

sliding the carriage. See Figure 3, Detail C.

5. Open the fiber clamp, and move the fiber slide

back until it stops.

6. Remove the cleaved fiber, and properly dispose

of the scrap fiber. If the fiber does not cleave,

repeat the process starting with Step 3 of

Paragraph 3.2.A.

Be careful to dispose of fiber ends properly. The

fibers create slivers that can easily puncture skin

and cause irritation.

DO NOT attempt to clean the fiber after it has

been cleaved.

Fibers must have a quality cleave before

terminating to the jacks. To ensure that the

cleave tool is producing quality cleaves, it is

STRONGLY RECOMMENDED to inspect at least

one fiber cleave per day according to the

following:

1. Fit the bare fiber adapter onto the universal adapter;

then assemble the universal adapter onto the microscope.

2. Using the microscope, inspect the fiber for a quality

cleave. Refer to the instructions packaged with the

microscope kit) for operating procedures and safety

precautions concerning the microscope.

IMPORTANT

ibers must be terminated as soon as

the cleaving and inspection process is complete;

otherwise, damage to the fibers could result.

Proceed to Paragraph 3.3.

3.3. Termination

DO NOT use build-up tubes, loose tube fiber,

easy-strip fiber, fan-out kits, or breakout kits.

IMPORTANT

For correct system polarity, Channel “A”

must be connected to Channel “B” and Channel “B”

must be connected to Channel “A” on any cable run

or cable assembly (including fiber optic equipment).

Refer to Figure 2.

Proceed as follows:

1. Holding the jack or placing the jack on a clean,

flat surface (the protective cover helps to keep the

jack stabilized), slide the fiber guide onto the back

of the jack. See Figure 4.

The fiber guide is marked with the fiber size.

Make sure that the marking on the fiber guide

corresponds with the fiber size being used.

2. With the handle of the actuation key pointing

toward the top of the jack, insert the key (pointed

end first) into the key hole for Channel A until it

stops (the entire key portion must be inside the

hole). See Figure 5, Detail A. DO NOT force the

key. With the key in this position, the fiber hole is

“closed.”

3. Slide the prepared fiber onto the slot on the fiber

guide and into the fiber hole until the fiber stops.

See Figure 5, Detail A.

4. While lightly holding the fiber in place,

SLOWLY

rotate the key handle 90

(one–quarter turn)

toward the outside of the jack. See Figure 5,

Detail B. With the key in this position, the fiber hole

is “open.”

Ensure that the key is rotated ONLY one-quarter

turn; otherwise, the fiber hole will be partially

open, and the fiber cannot be inserted.

5. Insert the fiber further into the fiber hole until it

bottoms. See Figure 6, Detail A. If the fiber stubs

while inserting it into the fiber hole, slightly turn the

fiber, and continue to insert the fiber into the hole.

The fiber is fully inserted into the fiber hole when

the stripped portion of the fiber is inside the jack.

6. Hold the fiber in place using enough pressure to

create a slight bow in the fiber, then

SLOWLY

rotate the key handle 90

(one–quarter turn)

toward the inside of the jack. DO NOT “flip” the key

handle. Refer to Figure 6, Detail B. The fiber is

now terminated to the jack.

7. Remove the key from the jack.

If preferred, use the visual fault locator to confirm

that the fiber is fully inserted into the fiber hole.

When the fiber is properly inserted, the laser (or

LED) light will diminish in the target area of the

jack. Refer to Figure 7.

If using the visual fault locator, avoid

contamination to the ferrule end face.

Make sure that the protective cover remains

clean when removed, and then before

proceeding, that the protective cover is

re-installed onto the jack.

If the ferrule end face is touched or otherwise

contaminated, clean the end face with canned air

before re-installing the protective cover.

TO AVOID PERSONAL INJURY, wear eye

protection.

8. Repeat the assembly procedure for Channel B.

Carefully

slide the fiber guide at least 76 mm

[3 in.] away from the jack, then carefully route the

fiber out of the slot in the fiber guide. Keep the

protective cover on the jack if not installing the jack

immediately.

3.4. Inspection

Remove the protective cover, and inspect the ferrule

end face for cleanliness using the microscope kit.

DANGER: Never View Active Fiber Signals

3.5. Installation

Refer to Instruction Sheet 408–8844 for instructions

on installing the jacks into the adapter plates, patch

panels, or enclosure or wall outlets.

408–4579 (packaged with the test kit) for instructions

on using the test kit and testing procedures.

5. REPLACEMENT AND REPAIR

Jack kit components are not repairable. Replace any

damaged or defective components. DO NOT re–use

the jacks by removing the fibers after a successful

termination.
