:: Sumitomo Lynx-CustomFit Splice On Connector Procedure

1. Remove housing-side covering from package

image

2. Insert the cordage through assembly parts

image

3. Insert cordage into appropriate groove (2mm or 3mm) of slitter using back of tool as stopping point.

image

4. Spin the slitter while holding the cordage creating a ring cut.

image

5. Pull the cord to remove the outer jacketing.

image

6. Pull the Kevlar to remove excess slack inside cord.

image

7. Insert cordage into appropriate groove (2mm or 3mm) of slitter using the back of tool as stopping point.

image

8. Using the back of the tool as a gauge, mark the fiber. This mark represents the ending strip point and reference point for the fiber holder edge.

image

9. While holding the tool, pull the cordage slitting the jacket in the process.

image

10. Fold the Kevlar and sheathing back.

image

11. Insert the fiber through the fiber protection sleeve.

image

12. Strip the fiber coating to the marked point.

image 

13. Clean the fiber.

image

14. Check for fiber breaks by gently snapping the end.

image

15. Set the fiber into the holder curl side down.

image

16. The 900 micron coating should be flush with the edge of the fiber holder.

image

17. Set the fiber holder into the fiber cleaver.

image

18. Slide the front tip of the holder until it touches cleaver.

image

19. Close the cover of the fiber cleaver, cutting the glass fiber.

image 

20. Place the holder into the fusion splicer from behind the v-groove.

image

21. Remove the ferrule side covering of the package. (open just before using the ferrule subassembly).

image

22. Insert the ferrule/fiber into holder and close the cover. Ensure that the glass fiber does not hit the holder.

image

23. Insert this holder into fusion splicer from behind the v-groove.

image

24. Close the fusion splicer’s cover.

image

25. Ensure that the fusion splicer is set for single fiber splicing and 60mm sleeve setting.

image

26. Complete the splice.

image

27. Open the ferrule holder. Remove the fiber from the splicer while maintaining tension on assembly to prevent bending.

image

28. Move the protection sleeve into position adjusting the sleeve by slanting the fiber.

image

29. DO NOT twist the ferrule subassembly or fiber. Sleeve should cover metal flange.

image

30. Center the fiber protection sleeve inside heater and complete the heat cycle.

image

31. After completing of heater cycle allow the assembly to cool at least 1 minute before removing.

image

32. Remove the tape from the outer sheath of the cordage and spread Kevlar.

image

33. Separate the crimp ring then slide the spring and rear housing up until they touch the back of the ferrule subassembly.

image

34. Pull the Kevlar and sheathing out from the rear housing.

image

35. Holding the metal screw of the fiber stub, remove the dust cap without pulling on fiber protection sleeve.

image

36. The ferrule should fit inside the key when using APC connectors align the red marks with each other.

image

37. Loose press the ferrule subassembly into the notched housing.

image

38. Gently press the dust cap onto the ferrule. The dust cap is being using as a temporary holder.

image

39. Align the groove and slide the inner housing over the rear housing until the components lock together.

image

40. Snap the string from the dust cap.

image

41. Divide the Kevlar into two tight bundles.

image

42. Spread the sheath and Kevlar around the rear housing.

image

43. While maintaining the position of the sheath and Kevlar, slide the protection tube down 1/4 inch above rear of housing.

image

44. Slide the crimp ring over the protection tube keeping sheath and Kevlar split.

image

45. Slide crimp ring until it touches rear of rear housing.

image

46. The larger diameter of the crimp tool (noted by red dot) should face the rear housing.

image

47. Crimp the crimp ring with the crimp tool. Be careful not to crimp the black part of the rear housing.

image

48. Rotate the connector by 90 degrees, and crimp again.

image

49. cut off excess Kevlar using snips.

image

50. Put the outer housing over the inner housing. Align the notch of the outer housing with the notch of inner housing.

image

51. Align the boot with the notch of the outer housing. Slide the rear boot until it stops.

image

53. Connector Cleaning.

It is recommended to keep the dust cap installed to maintain cleanliness and to prevent end-face damage before installation.

We recommends at a minimum following a simple wet dry connector cleaning procedure. The procedure will require using a lint free wipe in conjunction with 99% pure isopopyl alcohol being used as a cleaning solvent.

Dampen a small area of the wipe with alcohol. Staring on the dampened side the of the wipe, move the connector end-face from the wet area to the dry area in a single motion. Rotate the connector 90 degrees and repeat the process on clean section of the wipe.
