4 78-0013-1746-6-E 1.3 Additional materials needed: • De-ionized or distilled water for nano-finishing at above-freezing temperatures • 25% to 35% methanol by volume and 75% to 65% de-ionized or distilled water solution by volume for nano-finishing at below-freezing temperatures. DO NOT use ethanol or isopropyl alcohol for nano-finishing. • 9[...]

5 78-0013-1746-6-E 2.3 Remove the 3M ™ Crimplok ™ + Connector from the bag and remove the dust cap from the ferrule. Remove the lapping film disc from the bag and set it aside for later . 2.4 Insert the connector into the SC port with the actuation cap facing upward. Ensure the connector is fully seated in the port. Actuation Cap 3.0 Fiber Stri[...]

6 78-0013-1746-6-E 3.3 For 900 µm, determine if the fiber is tight or semi- tight buffer . If the 900 µm slides easily from the fiber, it is semi-tight buffer fiber . If not, it is tight buffer . Break-out kits for 250 µm are semi-tight. Make note of tight or semi-tight for step 3.1 1. 3.4 For semi-tight 900 µm buffer only , place a second fibe[...]

7 78-0013-1746-6-E 3.8 Close the left cover . Close the right cover . Push the shuttle forward to cleave the fiber . 3.9 Open the right cover . Use tweezers to carefully grab the glass shard. Discard it in the shard container . CAUTION: The glass shard is sharp and can pierce the skin. 3.10 Open all 3 lids on the fiber holder . Slide the shuttle fo[...]

8 78-0013-1746-6-E 3.1 1 Lay the fiber in the track running through the center of the fiber holder . Use the “TIGHT BUFFER” or “SEMI- TIGHT BUFFER” slits as appropriate. Reference section 3.3 to determine which fiber type. Tight buffer Semi-tight buffer 3.12 Move shuttle forward. Leave at least one finger width of buffer extending beyond th[...]

9 78-0013-1746-6-E 3.14 Rotate the fiber so the fiber curl is directed downward in the fiber holder . 3.15 Hold fiber at rear , and pull the fiber backward. Position the fiber so the tip is flush (±1 mm) with the end of the nozzle. Note: The 900 µm coating edge can be seen through a hole in the shuttle. V iewing this is a good method to check tha[...]

10 78-0013-1746-6-E 4.0 Fiber Insertion and Connector Activation 4.1 Grip the back of the fiber holder . Do not grip the front or middle lids, because they may need to pop open. Slowly insert the fiber holder (with cleaved fiber) into the guide track on the protrusion setting tool until it reaches a stop. Do not push or pull the back end of the fib[...]

11 78-0013-1746-6-E 4.4 For 250 µm only , the fiber will bow in the nozzle slot. No lids will open with 250 µm. Note: Bowing these 3 different fiber coating types at 3 different lengths enables consistent fiber protrusion setting. 250 µm coating 4.5 Rotate the activation lever on the protrusion setting tool 180° until the free end is positioned[...]

12 78-0013-1746-6-E 4.7 Press down hard on the free end of the activation lever to activate the fiber crimping mechanism within the connector . After a click sound, the lever will be stopped and cannot be pushed any further . Note: Never activate a connector without a fiber in it or with a fiber only partially inserted. Doing so will ruin the conne[...]

13 78-0013-1746-6-E 4.9 Open the covers and buffer clamp (if necessary) on the fiber holder (for stif f-coated fiber , the buffer clamp was already opened). Slide the fiber holder out of the guide track in the protrusion setting tool, leaving the connector and fiber behind. 4.10 Remove the connector from the port on the protrusion setting tool. Use[...]

14 78-0013-1746-6-E 5.2 W et the top surface of the finishing disc with 2 squirts of de-ionized water using the spray bottle provided. A void using excessive amounts of water . Close the lid fully and ensure the latch is engaged. Note: W etting the disc surface is important because it carries off glass particles that have been removed. Failure to w[...]

15 78-0013-1746-6-E 5.7 Remove the lapping film. Inspect the lapping film for fiber tracks. If the film has tracks, dispose of it. If not, restart at step 5.1. APC UPC 5.8 Dry the connector using a new lint-free wipe. Do not use the same wipe used for stripping fiber . Fold the wipe to provide cushion. For APC, tilt the connector so the ferrule tip[...]

16 78-0013-1746-6-E 5.9 Before the network has a laser light source feeding your connector , inspect the fiber end face with 3M ™ 200X V iew Scope 6365-VS if you have one. If the fiber end face looks acceptable per photos to the right, then re-insert the connector into the protrusion setter and activate the buffer clamp per step 4.8. If the conne[...]

17 78-0013-1746-6-E 6.0 Connector Reusability 6.1 Should it become necessary to separate the connector and fiber , e.g. to reset the fiber protrusion, the activation cap within the connector can be deactivated. This is accomplished by first removing the connector from the port on the protrusion setting tool. Place the connector atop the deactivatio[...]
