  5. 5.  Load the mixed epoxy into a syringe (unless its pre-loaded of course). Inject the epoxy into the back end of the connector ferrule. Insert the prepared cable into the connector such that the bared fiber is inserted into the ferrule hole. Insert until the cable seats inside the connector. The fiber will be protruding out the front of the ferrule by typically ½ inch. Crimp: If the connector is being installed onto jacketed fiber, a crimping operation is required to retain the connector onto the cable strength members and jacket. This is usually accomplished via use of a crimp sleeve and, in order to retain the connector onto the cables strength members as well as the jacket, two crimps are typically required.
  6. 6.  Insertthe bare fiber into the connector Perform crimping Cleaving (manual or auto)
  7. 7. PATCHCORD
  8. 8. A patch cable or patch cord is an electrical or optical cable used to connect ("patch-in") one electronic or optical device to another for signal routing. Firstly, Crimping kevlar sleeve onto the connector Slide the strain relief boot up to the connector
  9. 9.  A fibre is a single short, usually unbuffered, optical fibre that has an optical connector on one end and a length of exposed fibre athe other end. The end of the pigtail is stripped and fusion spliced to a single fibre of a multi-fibre trunk to break out the multi- fibre cable into its component fibres for connection to the end equipment. Pigtails can have female connectors and be mounted in a patch panel A plastic boot is normally used for strain relief and protection from moisture.
  10. 10. End-surface treatment for proper light propagation
  11. 11. Polish film made Diamond, silicon carbide, andaluminum oxide
  12. 12. POLISHING TYPE FOR CONNECTOR
  13. 13. most popular type . . . UPC (Ultra-Physical Contact), and themore recent APC (Angle Polished Connector). UPC (coded blue/black) APC (Green)
  14. 14. 1. Air polish
  15. 15. 2. Surface polish
  16. 16. 3. Fiber optic micro polisher
  17. 17. •Toinspect the quality of the fiber surface. •Using a microscope100x,200x(Multimode Inspection) 400x(Singlemode Inspection)
  18. 18.  Insertion Loss & Return Loss Return Loss are two importance data to evaluate the quality of many passive fiber optic components,such as fiber optic path cord and fiber connectors, etc.
  19. 19.  Insertion Loss refers to the fiber optic light loss coused when a fiber optic component insert into another one to from the fiber optic link. Insertion loss can result from absorption, misalignment or air gap between the fiber optic components. Return Loss is the fiber optic light gets reflected back at the connection point. The higher return loss means the lower reflection and better the connection. According to industry standard, Ultra PC polished fiber optic connectors return loss should be more than 50dB, Angled polished generally return loss is more than 60dB. PC type should be more than 40dB.
