COMPONENT IDENTIFICATIONREAD ALL INSTRUCTIONS COMPLETEL Y BEFORE PROCEEDING1.4 ITEMS REQUIRED FOR TERMINATION2. PRECAUTIONS2.1SAFETY GLASSESWARNING : Safety glasses have to be worn when handling the adhesive or primer used with the connector or when handling bare optical fiber. The bare fiber is very sharp and can easily damage the eye.2.2ISOPROPYL ALCOHOLWARNING : Isopropyl alcohol is flammable. Contact with the alcohol can cause irritation to the eyes. In case of contact with the eyes, flush with water for at least 15 minutes. Always use isopropyl alcohol with proper levels of ventilation. In case of ingestion, consult a physician immediately.2.3RECOMMENDED ADHESIVE AND PRIMERWARNING : The recommended adhesive (Panduit Part #FJPXY) may contain maleic acid and methacrylic ester. In case of eye contact, flush with water for 15 minutes and get medical attention. Wash after skin contact. Request M.S.D.S. for further safeguards. Check “Used By” date on bottle to ensure best performance.WARNING : The recommended primer (Panduit Part #FJPMR) may contain acetone. The primer is harmful if inhaled or swallowed. In case of contact with eyes or skin, flush with water. Get medical attention in case of ingestion or contact with eyes. Do not induce vomiting. Check “Used By” date on bottle to ensure best performance.2.4DISPOSAL OF BARE FIBERSWARNING : Pick up and discard all pieces of bare fiber with sticky tabs. Do not let cut pieces of fiber stick to clothing orFERRULE TERMINATIONTERMINATION PREPARATIONRemove the plunger from a syringe. Squeeze a b out 0.5 ml of FJPXY Anaero b ic Adhesive into the b ack of the syringe b arrel. Insert the plunger. Point opening upward, and squeeze any air out of the b arrel. Attach needle to syringe. Adhesive that is stored in a syringe may start to harden within 24 hours.Partially fill a second syringe with a b out 0.5ml of FJPMR Primer. Do this b y drawing primer up into the syringe b arrel rather than pouring it in through the b ack.3.0mm/2.0mm/1.6mm JACKET & 900µm BUFFER STRIPPINGRefer to Page 1 or appropriate Panduit laminated template for stripping dimensions.For jacketed duplex cable: Split the two ca b les approximately 6" (152mm) or as needed depending on desired jacket stripping length.Insert the fi b er end through the small end of the appropriate b oot for your specific fi b er type. Slide the b oot b ack out of the way. For jacketed cable only: To reduce wear on the jacket stripper b lades, do not slide the b lades along the aramid yarn. Instead, use the tool to cut through the jacket, then pull off the jacket b y hand. For 3.0mm jacketed fiber, use the third hole (marked “1.3MM” or #16AWG) from the tip of the jacket stripper. For 2.0mm/1.6mm jacketed fiber, use the first hole (marked “.80MM” or #20AWG) from the tip of the jacket stripper. Using the ca b le jacket stripper, strip therequired length of the jacket off of each fi ber according tothe stripping dimensions.For jacketed cable only: Insert the fi b er through thesmaller end of the crimp sleeve. Use the crimp sleeve tofold the aramid yarn b ack over the jacket, holding it out ofthe way.For jacketed cable only: Use the marking pen andstripping dimensions provided to mark the b uffer from theend of the jacket.3.2.6For 900µm buffered fiber only: Using the marking pen,place a mark 1" (25mm) from the end of the b uffer.3.3.5DROP OF PRIMER3.3.63.3FERRULE ATTACHMENTInstructions intended for anaerobic adhesive only.3.3.1Clean the b are fi b er using an alcohol (90% minimumconcentration) soaked lint-free wipe. The fi b ers should b e free of all coating and residue after cleaning. Insert fi b er without adhesive or primer into ferrule assem b ly to ensure a proper fit and to remove any de b ris which may b eb locking the ferrule hole. Remove fi b er, clean fi b er again, and proceed to the next step.3.3.2Apply primer onto the b are fi b er with the b rush from theprimer b ottle, and onto the first 1/8" (3.2 mm) of the b uffer next to the exposed fi b er. Set fi b er aside such that it will not collect de b ris while completing the next three steps.3.3.3Insert the needle of the adhesive filled syringe into theferrule assem b ly until the needle b ottoms against the rear of the ferrule. 3.3.4While pressing the needle firmly against the rear of theferrule, gently squeeze the syringe plunger until you see a small b ead of adhesive form on the front tip of the ferrule. Pull syringe out of the ferrule assem b ly. 3.3.5Carefully b ut quickly insert the b are fi b er through theferrule in a smooth forward motion. The fi b er is fully inserted when the b uffer b ottoms against the rear of the ferrule. The adhesive will b egin to set within seconds. Note: If adhesive oozes out the back of the assembly, you have injected too much. It is critical to the function of the connector that you wipe away all excess adhesive.3.3.6To speed hardening of the adhesive, apply a small drop ofprimer to the adhesive b ead on the ferrule tip using the primer filled syringe. Do not allow the primer to come in contact with the plastic housing of the ferrule assem b ly. A b sor b any primer and unhardened adhesive from the ferrule tip b y gently da bb ing it with the corner of a lint-free wipe. Be careful not to break the fiber.3.3.7Allow one minute for the adhesive to harden b eforecleaving.•Clean the b uffer stripper b lades after each strip b y holding the handles open, pulling the casings b ack away from the b lades, and letting them snap b ack against the b lades.CRIMPINGFor jacketed cable only .Note: Be careful not to break the bare fiber protruding from the ferrule during this step.Slide the crimp sleeve b ack, freeing the aramidyarn. The ca b le jacket should nearly touch the rear of the b ack b one of the ferrule assem b ly.Note: Do not press the cable jacket forward to touch the rear of the backbone. There should be a gap between the jacket and backbone.With the appropriate strength mem b er (aramidyarn) cutters, cut the aramid yarn even with the flange. Flare the aramid yarn evenly around the perimeterof the grooved area of the b ack b one of the ferrule assem b ly. For 2.0mm/1.6mm jacketed cable , use tweezers for b est results.Slide the crimp sleeve over the b ack b one, trappingthe aramid yarn b etween the crimp sleeve and the b ack b one.

This is indicatedwhen the white trace on the film is no longer o b vious. Make surefingers are at the edge of the film, not directly b ehind fi b er.Note: Do not use the same 5µm film used in this step for anyof the following polishing steps.4.2Thoroughly clean polishing puck, puck hole, and pad with alcoholand cleaning swa b. Place a separate sheet of 5µm polishing filmon the soft side of the polishing pad. Set the polishing puck on thepolishing film.4.3Carefully insert the inner housing assem b ly into the puck hole untilthe ferrule/fi b er contacts the polishing film. While keeping the puckflat against the film, apply very light pressure on the ferruleassem b ly making figure eight motions with the puck. Graduallyincrease pressure until the fi b er stu b no longer leaves a white traceon the film (a b out 10 figure eights). At this point, the adhesive willb e gone.4.4Remove 5µm polishing film from polishing pad. Clean the ferruletip, pad, and b ottom of the puck with an alcohol soaked wipe.4.5Place a sheet of 1µm diamond polishing film onto the polishingpad. Place several drops of distilled water on the diamond film.Polish the fi b er endface with the puck using medium pressure forapproximately 10 figure eights.4.6Clean the ferrule tip and puck with an alcohol soaked lint-free wipe.Clean the 1µm diamond film using an alcohol soaked wipe afterevery 5 connectors.4.7Inspect the fi b er endface using a microscope. If scratches remain,repeat steps 4.5 and 4.6.WARNING: NEVER LOOK INTO THE END OF A FIBER WHICHMAY HAVE A LASER COUPLED INTO IT.Note: Each time a mating takes place, clean the ferruleendface thoroughly with an alcohol soaked lint-free wipe.4.8For singlemode only: Place a sheet of the .05µm lapping film onthe pad. Apply several drops of distilled water onto the center ofthe film.4.9For singlemode only: Place the puck in the center of the distilledwater on the film and pad. Keeping the puck flat against the filmand pad, apply even pressure for 4 figure eights.4.10For singlemode only: Wipe the ferrule, pad, and puck with a drywipe.4.11For singlemode only: Clean the ferrule with a distilled watersoaked wipe. Do not use alcohol to clean after using the .05µmlapping film.4.2UNIVERSAL POLISHING PUCKPOLISHING GUIDELINES•Keep the puck flat against the polishing film.•Figure eights should b e a b out 3" tall and 1.5" wide.•Always polish on a clean area of the 5µm (micron) polishing film, withfigure eights traversing the film as shown in Figure 4.3.•One sheet of 5µm (micron) polishing film will polish 2-4 ferrules.•One sheet of 1µm diamond polishing film will polish 100 ferrules.•One sheet of .05µm lapping film will polish approx. 18-20 ferrules.•Clean the polishing puck and pad with a clean wipe after each step.•DO NOT OVERPOLISH.Boot againstflange 6.1.36.FINAL CONNECTOR ASSEMBL Y 6.1Boot Installation6.1.1For jacketed cable only: Align the b oot so that the firstset of slots is aligned with the top of the inner housingassem b ly.6.1.2For jacketed cable only: Slide the b oot over the crimpsleeve and onto the b ack b one.

通常「光纤」与「光缆」两个名词会被混淆.多数光纤在使用前必须由几层保护结构包覆,包覆后的缆线即被称为「光缆」。

光纤外层的保护结构可防止周遭环境对光纤的伤害,如水,火,电击等.光缆分为:光纤,缓冲层及披覆.光纤和同轴电缆相似，只是没有网状屏蔽层。

中心是光传播的玻璃芯。

在多模光纤中，芯的直径是15mm~50mm，大致与人的头发的粗细相当。

而单模光纤芯的直径为8mm~10mm。

芯外面包围着一层折射率比芯低的玻璃封套，以使光纤保持在芯内。

再外面的是一层薄的塑料外套，用来保护封套。

光纤通常被扎成束，外面有外壳保护。

纤芯通常是由石英玻璃制成的横截面积很小的双层同心圆柱体，它质地脆,易断裂,因此需要外加一保护层。
