See Figure 5, Detail D. Detail D Spring 10. Pre-heat the heat cure oven to 100_C. 11. Prepare the epoxy according to the following: Bare Fiber a. Remove the separating clip from the epoxy package. Using the epoxy mixer, mix the two components together thoroughly for 20 to 30 seconds. Fiber Buffer Figure 5 b. Install the needle tip on the applicator from the epoxy applicator kit. Make sure it is secure. Remove the plunger. c. Cut the epoxy packet open, and squeeze the epoxy into the back of the applicator. Re-assemble the plunger. Hold the applicator vertically, and slowly push on the plunger until the entrapped air escapes and a bead of epoxy appears at the needle tip. d. Using a lint-free tissue or cloth dampened with the isopropyl alcohol or acetone, clean the tip of the applicator. 12. Hold the ferrule assembly vertically, and insert the needle tip into the base of the ferrule assembly until it is against the back (end closest to the base) of the ferrule assembly. Refer to Figure 6. 4 of 11 Tyco Electronics Corporation 0.75-mm Diameter (Approx) Bead of Epoxy Base of End Face of Ferrule Assembly Ferrule Assembly Applicator Needle Figure 6 Rev B 408-10222 PRO BEAM Jr. EB Cable Plug Connectors 13. While holding the ferrule assembly firmly against the needle tip, slowly inject the epoxy until a small bead of epoxy (approximately 0.75 mm in diameter) forms at the end face of the ferrule assembly. DO NOT allow the bead to get too large or smear. 14. Withdraw the needle slightly, and inject an additional small amount of epoxy so that the cavity at the base of the ferrule assembly is approximately one-third to one-half full. DANGER Curing Fixture Cable To avoid personal injury, remember that epoxy is a hazardous material, and pay particular attention to the following: ALWAYS follow manufacturer's safety guidelines. Fiber Base and O-Ring of Ferrule Assembly ALWAYS wear protective gloves when using epoxy. Spring Crimp Sleeve ALWAYS use epoxy in a well ventilated area. AVOID prolonged and frequent contact with skin. Assembly After Curing AVOID inhaling fumes from epoxy. 15. Place the crimp sleeve and fiber into the curing fixture according to the instructions included with the curing fixture. 65.5+1/-0 mm Required Functional Length Carefully insert the fiber into the back of the ferrule assembly (previously prepared with epoxy). Simultaneously slide and rotate the ferrule assembly on the fiber (to prevent any air pockets from being trapped in the epoxy) until it bottoms. Make sure that the bare fiber is protruding from the end face of the ferrule assembly. If it is not, re-strip and re-terminate the fiber. Figure 7 After Scoring, Pull Fiber Straight Away Place the ferrule assembly in the curing fixture according to 408-8857 (instructions included with the curing fixture). Fiber 16. Cure the assembly in the heat cure oven for 20 minutes. Remove the assembly from the oven, and allow the assembly to cool to room temperature. Epoxy 17. Remove the assembly from the curing fixture according to 408-8857. Measure the assembly to make sure that it conforms to the dimension given in Figure 7. If it does not, re-strip and re-terminate the fiber. NOTE Scribe Tool End Face of Ferrule Assembly Figure 8 Although the curing fixture is designed to ensure that the required functional length is obtained, it i is still important to measure the assembly for this length after curing. DANGER Safely dispose of excess fiber. CAUTION To avoid damage to the tip of the scribe tool, 5.3. Cleave the Fiber Firmly support the ferrule assembly, and draw the beveled edge of the scribe tool across the fiber as shown in Figure 8. After scoring the fiber, pull the fiber straight away from the ferrule assembly. Rev B DO NOT allow the scribe tool to contact the ! Tyco Electronics Corporation epoxy. 5 of 11 408-10222 PRO BEAM Jr. EB Cable Plug Connectors 5.4. Polish the Fiber It is recommended polishing the fiber using a polishing machine. The polish must produce a super-physical contact (PC) end finish for singlemode connectors and a flat end finish for multimode connectors. Machine polishing produces the best results. Polish the fiber according to the machine manufacturer's instructions. Polishing Bushing Figure-8 Pattern If machine polishing is not possible, hand polish the fiber according to the following: 1. Using a small piece of the 5-mm polishing film, remove the fiber stub to the level of the epoxy. 2. Install the ferrule assembly onto the polishing bushing. 3. For singlemode connectors, place the green polishing pad on the polishing plate. Place the 5-mm polishing film on the green polishing pad. Figure 9 For multimode connectors, place the polishing plate on a hard flat surface. Place the 5-mm polishing film on the polishing plate. 4. Hold the ferrule assembly and rest the tips of your index finger, middle finger, and thumb on the top of the polishing bushing. Starting with very light pressure, polish the tip of the fiber in a figure-8 pattern. Refer to Figure 9. Polish the fiber until the epoxy turns a very light yellow. NOTE 9. Remove the ferrule assembly from the polishing bushing. Clean the end face and sides of the ferrule assembly with isopropyl alcohol or acetone and a lint-free tissue. DO NOT remove all the epoxy. As the epoxy gets lighter, check the tip of the fiber frequently. i 5. Clean the end face of the ferrule assembly and polishing bushing with isopropyl alcohol or acetone and a lint-free tissue. 6. Place the 0.3-mm polishing film on the polishing pad (singlemode) or polishing plate (multimode). Polish in a figure-8 pattern. Stop polishing as soon as all the epoxy is removed. 7. Clean the end face of the ferrule assembly and polishing bushing with isopropyl alcohol or acetone and a lint-free tissue. 8. Place the final polishing film on the polishing pad (singlemode) or polishing plate (multimode). Apply several drops of water to an unused area of the film. Move the ferrule assembly in 20-mm circles on the water for 25 seconds. NOTE One sheet of final polishing film will be sufficient for 10 to 20 ferrule assemblies. i 6 of 11 Tyco Electronics Corporation Rev B 408-10222 PRO BEAM Jr. EB Cable Plug Connectors 5.5. Inspect the Ferrule Assembly and Fiber DANGER Never inspect or look into the end of a fiber when optical power is applied to the fiber. The infrared Ferrule Assembly Tip Acceptable Small Peripheral Chips Fiber light used, although it cannot be seen, can cause injury to the eyes. 1. Using the microscope, inspect the ferrule assembly and fiber according to the following criteria (refer to Figure 10): Fine Polishing Lines -- Make sure that any epoxy is removed from the ferrule assembly -- Dirt may be mistaken for small pits. If dirt is evident on the ferrule assembly or fiber, clean with isopropyl alcohol or acetone and a lint-free tissue, then dry Ferrule Assembly Tip Unacceptable Dark Scratches Fiber Large Chips -- Fine polishing lines are acceptable -- Small peripheral chips (at the outer rim) on the fiber are acceptable -- Large chips in the center of the fiber and dark scratches are unacceptable, and the fiber must be re-terminated 2. If necessary, install the dust cover onto ferrule assembly to prevent contamination to the end face. Figure 10 Detail A 5.6. Complete the Assembly 1. Remove the protective label from the back (end opposite the lens) of the EB insert. 2.
