3 SECTION A Warnings, Recommendations and Overview 1. Most fibers can be mechanically stripped without the aid of chemicals or heat. If the fiber is not mechanically strippable, contact 3M's Training Department or the cable manufacturer for their recommendations.
4 (A) - Strain Relief Boot (B) - Crimp Ring (C) - Connector (D) - Housing SECTION A Warnings, Recommendations and Overview This manual is for terminating the following field mountable connectors: Iden.
5 Fig. B1 SECTION B Jacketed Cable Preparation This section is for mounting the 3M brand SC and FC/PC3 field- mountable connectors on 2.4 mm cable and 3.0 mm cable. The process for mounting on 900 ϑ m buf fered fiber can be found in Section H. 1. TURN THE OVEN ON When the oven is heated to the proper temperature the heater light will go of f.
6 SECTION B Jacketed Cable Preparation 5. SLIP THE STRAIN RELIEF BOOT AND THE CORRECT CRIMP RING ONT O THE CABLE DO NOT FORGET T O DO THIS STEP . The boot will not fit over a mounted connector assembly so it is essential that it be slipped onto the cable at this time.
7 SECTION B Jacketed Cable Preparation 9. BUFFER REMOV AL With the modified No-Nik tool's arrow pointing in the direction of the stripping, remove the fiber's buffer in small bites, about 3/16" (5 mm). Be sure to remove the stripped material from the tool after each incremental cut.
8 SECTION C Mounting 1. INSPECT THE CONNECT OR Before mounting, hold the connector up to a light to ensure that the capillary hole of the ceramic ferrule is clear . If the hole is obstructed, blow it clear with air or use a piece of stainless steel wire supplied with the kit.

PREP ARE THE SYRINGE AND EPOXY Remove the plunger and protective cap from the syringe and place both parts on a clean convenient surface along with the dispensing tip. The epoxy supplied has been specifically designed for use with fiber optic connectors and is packaged in premeasured 2 gram bi-packs.
10 Fig. C8 Fig. C9 Fig. C10 Fig. C11 SECTION C Mounting 8. THREAD THE CONNECTOR ONT O THE FIBER Slide the crimp ring up the cable within 1/2" (13 mm) of the end of the jacket. Hold the cable in one hand directly behind the crimp ring and hold the connector in the other hand.
11 Fig. C12 Fig. C13 SECTION C Mounting 1 1. SECURE THE STRAIN RELIEF BOOT Use the syringe to apply two dabs of epoxy onto the larger half of the crimp ring (Fig. C12). While holding the load adapter , slide the boot up over the crimp ring and rotate it to evenly distribute the epoxy .
12 SECTION D Scoring 1. CAREFULL Y REMOVE THE LOAD ADAPTER 2. SCORE THE FIBER Hold the connector in a vertical position with the fiber pointing upward. Score the fiber by drawing the scoring blade lightly against the fiber , just above the epoxy bead (Fig.
13 SECTION E Standard Polishing Process for Single-mode and Multimode Connectors (>30dB) Note: See Section F to achieve >40 dB Return Loss. 1. PREP ARE THE 5 ϑ m POLISHING SURF ACE Clean the surface of the soft polishing pad with a lint-free cloth dampened with isopropyl alcohol.
14 SECTION E Standard Polishing Process for Single-mode and Multimode Connectors 3. PERFORM THE 5 ϑ m FINISH While holding the polishing jig in your hand, insert the connector so that the ferrule end does not protrude past the bottom of the polishing jig.
15 SECTION E Standard Polishing Process for Single-mode and Multimode Connectors 4. PREP ARE T O PERFORM THE 1 ϑ m FINISH Using an isopropyl alcohol dampened lint-free cloth, clean the ferrule, the polishing jig, and the 5 ϑ m lapping acetate. Blow all pieces dry with compressed air .
16 SECTION F Polishing Process for Single-mode Connector Return Loss >40dB This process will need to be used for single-mode finishes with a reflection requirement of 40dB or better . This specification is outlined in Bellcore TR-NWT-00326 Issue 3.
17 SECTION F Polishing Process for Single-mode Connector Return Loss >40dB 4. PERFORM THE 5 ϑ m FINISH While holding the polishing jig in your hand, insert the connector so that the ferrule end does not protrude past the bottom of the polishing jig.
18 SECTION F Polishing Process for Single-mode Connector Return Loss >40dB 6. PERFORM THE 1.5 ϑ m FINISH Insert the ferrule into the jig and lower it gently onto the 1.5 ϑ m acetate. Using medium pressure (equivalent to 1 lb of force), perform four figure 8 strokes.
19 SECTION F Polishing Process for Single-mode Connector Return Loss >40dB 7. PREP ARE TO PERFORM THE FINAL POLISH Using an isopropyl alcohol dampened lint-free cloth, clean the ferrule and the polishing jig. Clean a sheet of the final polishing film and place it shiny side down onto the clean polishing pad.
20 SECTION G Final Cleaning 1. BLOW THE DUST CAP WITH COMPRESSED AIR 2. WIPE THE CERAMIC FERRULE WITH AN ISOPROPYL ALCOHOL DAMPENED LINT-FREE CLOTH (Fig.
21 SECTION H Mounting Unjacketed/900 m Buffered Fiber 7. THREAD THE CONNECTOR ONT O THE FIBER Slide the strain relief tube with the crimp ring within 1/2" (13 mm) of the buffer .
22 SECTION I Connector Assembly and Installation 1. CONNECT OR ASSEMBL Y Once the SC connector has been mounted and polished, the housing can be installed onto the body . A. Standard Density Applications While holding the connector firmly by the boot, align the chamfers on both the connector and housing and snap into place (Fig.
23 SECTION I Connector Assembly and Installation Fig. I5 Fig. I6 4. SC CONNECTOR - HIGH DENSITY MA TING Installation A. Clean the connector and coupling as described above. B. Hold the connector by the boot. C. Align the connector chamfers with the coupling (Fig.
