1. INTRODUCTION

LightCrimp Plus ST �ber optic connector kits aredesigned for use with 125--mm singlemode ormultimode glass �ber optic cable. These kits can beused with any of the following media (paragraph ofassembly procedure is indicated next to media).

5.1. 900-mm Bare Bu�ered Fiber

5.2. 250-mm Coated Fiber

5.3. 2.0- to 3.0-mm Loose Jacketed Cable

5.4. 900-mm Easy Strip or Semi-Tight Bu�ered Fiber

Read these instructions thoroughly before assemblingthe connector kits.

All numerical values in this instruction sheetare in metric units. Dimensions are inmillimeters Figures are not drawn to scale.

Reasons for reissue of this instruction sheet areprovided in Section 6, REVISION SUMMARY.

2. DESCRIPTION (See Figure 1)

Each connector kit consists of a connector assembly,strain relief, inner eyelet, crimp eyelet, black tubing,and clear tubing. Each kit is also supplied with a barebu�er boot and small tubing to compensate for smalldiameter cable. Also included, assembled onto theconnector, is a ferrule protective cover for the ferrule(front of connector) and a plunger protective cap forthe plunger (rear of connector).

3. SAFETY PRECAUTIONS

NEVER look into the end of terminated orunterminated �bers. Laser radiation is invisiblebut can damage eye tissue. NEVER eat, drink, orsmoke when working with �bers. This could leadto ingestion of glass particles.

Be very careful to dispose o� ber ends properly.The �bers create slivers that can easily puncturethe skin and cause irritation.

DO NOT use defective or damaged components.Replace them with new components.

A. Preparing 900-mm Bare Bu�ered Fiber(Figure 2)

1. Slide the bare bu�er boot (small diameter end�rst) over the bu�er. See Figure 2, Detail A.

2. Remove the ferrule protective cover and theplunger protective cap from the connectorassembly. Keep the cover; discard the cap.

3. Push the connector into the holder of the cableholder assembly with the ferrule protective coverfacing outward. See Figure 2, Detail B. Make surethat the connector butts against the lip of the armof the cable holder. Slide the �ber into the channelmarked “BUFFER” on the cable holder. Make surethat the tip of the bu�er butts against the end of thechannel.

4. Mark the bu�er at each cross--slot of thechannel. See Figure 2, Detail B. Remove the bu�erfrom the cable holder.

5. Using the strip tool, strip the �ber to the �rstmark. It is recommended holding the strip tool atan angle to the �ber and stripping the �ber in threesections. See Figure 2, Detail C. Clean the �berwith an alcohol �ber wipe to remove the �bercoating residue.

Before using the strip tool, make sure that the “V”opening is clean; otherwise the �ber could break.Only use isopropyl alcohol on the tool.

B. Cleaving (Figure 3)1. Open the �ber clamp of the �ber optic cleaver.Press the button, and slide the carriage back(toward the �ber clamp). Then move the �ber slideback until it stops.

2. Place the stripped �ber into the slot so that theend of the bu�er is at the 8--mm marking. SeeFigure 3, Detail A.

3. While applying pressure on the bu�er, carefullyslide the �ber slide forward (toward the carriage)until it stops. See Figure 3, Detail B.

4. Gently close the �ber clamp, and slide thecarriage forward. DO NOT touch the button whilesliding the carriage. See Figure 3, Detail C.

5. Open the �ber clamp, and move the �ber slideback until it stops.

6. Remove the cleaved �ber, and properly disposeof the scrap �ber.

DO NOT attempt to clean the �ber after it hasbeen cleaved.

C. Crimping (Figures 4 and 5)1. Open the cable clamp of the cable holder, andhold the bu�er (with the cleaved end o� ber facingthe connector) inside the clamp. Pull the end of the�ber even with the front of the arm of the cableholder, and holding the bu�er in place, close theclamp. See Figure 4, Detail A.

2. Carefully insert the �ber into the plunger of theconnector assembly until the �ber bottoms againstthe internal �ber. Make sure that the remainingmark on the bu�er enters the plunger. Theresultant bend in the bu�er should hold the �beragainst the internal �ber. See Figure 4, Detail B.

It is important that the �ber bottoms against, andremains against, the internal �ber. If the markdoes not enter the plunger or if the �ber does notseem to bottom against the internal �ber, the�ber may be caught on internal guides. Rotatingthe connector and backing the �ber out a smallamount and re--entering may help. However, ifthe mark will not enter the plunger, the �ber mustbe re--stripped.
