Necessity of cleaning
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. (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
