For high-speed optical transfer and WDM, there is more and more energy of over 1W output power from laser LD. How is it going if there exits pollution and dust on the end face?
● Fiber may fuse because of pollution and dust heating. (In foreign countries,it is limited that the fiber connectors and adapters should suffer over 75 ℃).
● It can cause damage to the laser equipment and influence the communication system because of light reflex (OTDR is very sensitive).
Effect of Dust Heating by High-Energy Laser
● Burn the fiber stub
● Fuse the surrounding of fiber stub
● Melt the surrounding metal powder of fiber stub
Comparison
Tools | Reasons of Undesired Effects |
Optic Fiber Stick and Electronic Optic Fiber Cleaner | 1) Though it is good at the first cleaning, there is secondary pollution after repeated use. (Secondary pollution is avoided by our CLEP because the cleaning part will be updated after use).
2) High cost. |
Non-Woven Fabrics (Clothes or Towel) and Cotton Ball Rod | 1) It is not suitable for the final cleaning because of the depilation.It may cause of failure.
2) The Metal powder and dust will cause damage to the fiber end face. |
High Pressure Gas | 1) It is good for the floating dust at a non-contact method. However there is little effect to the backlog dust.
2) There is little effect to the oil. |
