  1. DIAMONDPower Solution Fiber optic interface for high power applications

  2. Why and how to obtain a high power fiber optic connector

  3. Why a high power fiber optic connector? The following questions must be answered: • Which are the most common installations today? • What are future market requirements? • What are the most important parameters of an optical connector? We believe the answers are as follows: • Communication networks are getting bigger, and the information traffic every day denser. The maximal power used in common fibers has now increased to 500 mW or even more. • Dense Wavelength Division Multiplexing (DWDM) technology allows sending many different signals in the same line, each of them having a certain amount of power, which added up in the main cable make it reach high power values. • An up-to-date connector must be suitable for long distance transmissions and customer access furthermore present easy and secure handling, excellent as well as repeatable optical parameters, also under rough conditions.

  4. High quality manufacturing process • Computer assisted active core alignment • extremely reduced core eccentricity • high precision tilt angle measurement • guarantee of higher random mating repeatability • low connection losses • Low energy dispersion

  5. Safety trough connectors’ protection cap • Black chrome-plated metal protection cap as a standard component for E-2000™ and F-3000™ connector families. • Fully respects of current security requirements • Suitable for high power applications The black chrome plated metal cap features superior protection than any other previous solutions, presenting high optical isolation and very resistant construction.

  6. Safety trough adapters’ protection cap • Carbon reinforced protection caps for E-2000™& F-3000™ PS mating adapters • Fully respects of current security requirements • tested 24 Std. with 1 W power (E-2000™) • superior protection against undesirable radiation thanks to its high optical isolation • reduced temperature increase thanks to better thermal dissipation

  7. High power technology

  8. High Power Connector As the silica doesn't absorb the light, it doesn’t warm up and so there is no risk inside the fiber. The critical location is at the connections. At the junction, the fiber could be contaminated by dust or any kind of dirt, and the material deposited on the fiber will absorb part of the light and might warm up to a very high temperature, and hence there is a risk of damaging the fiber. Within the fiber core, which has a diameter of 9 µm, using a power of 1 W, the superficial power density reaches a value of roughly 10-15 GW/m2. (Solar surface power density is 62.6 MW/m2) In order to have a solution suitable for high power applications with max. target power at 3 W, Diamond has developed a special E-2000™ PS & F-3000 PS connectors based on standard components.

  9. Standard SM fiber • A perfectly cleaned connector can withstand up to 1 W without problems • With a slightly contaminated connector, the dirt particles will absorb light and convert it to heat • Danger: the fiber could melt and collapse Simulation: burnt SM fiber

  10. Fiber with expanded beam Solution: increase the mode field diameter at the connector interface the power density is lowered to a harmless value Singlemode: (spot  9 mm) Simulation: High Power: (spot  32 mm)

  11. GRIN fiber SM fiber GRIN fiber SM fiber splice splice connector 1 connector 2 Computer simulation: 10 GW/m2 1 0.1 Fiber with expanded beam Execution: use of a gradient index fiber (acts as a lens) to enlarge the spot

  12. High power production process

  13. Fiber splicing • Splicing of MM to SM fibers is critical because of material difference • Diamond ZEUS fusion splicer with multimode and SM fiber capability • Fiber-to-fiber alignment on 125µm diameter Multimode to single mode splice ZEUS fusion splicer

  14. High precision fiber cleaver • The fiber must be cleaved at the right distance (defines the focal length!) • Fiber cleaver including microscope and video camera for precise length measurement and splice quality assessment Fibers after cleavage Cleaver with video camera

  15. The fiber must be glued within the ferrule in the right position Special ferrule holder for the glue polymerization within standard oven Multimode fiber is very sensitive to stress because of larger core diameter Ferrules are pre- crimped (1° crimping) with metal wire Centering and Curing First crimping device Ferrule holder

  16. Collimation measurement • Expanded beam connectors are very sensitive to the focal length • CCD camera to measure the collimation • during polishing steps Measurement of diameter

  17. Pre-polishing (0°) • High power connectors need polishing process to optimize the length of the multimode fiber • Manual polishing steps Pre-polishing

  18. Active angle alignment • Angular misalignment induces high insertion loss because of lens system • second crimping device: crimping is carried out to straighten the output beam direction, not to reduce core eccentricity which is less critical before 2nd crimping: angle=0.5°  IL=1.5 dB after 2nd crimping: angle<0.1°  IL<0.5 dB Second crimping device

  19. Final polishing (APC 4°) • Automatic final polishing • APC 4° polishing • Achieve the right • geometrical parameters • Ensure optimal Return Loss Polishing machine
