Fiber Optic transmitters and receivers are extremely susceptible to contamination by 
particles of dirt or dust, which can obstruct the optic path and cause performance 
degradation.  Good system performance requires clean optics and connector ferrules. 

1.  Use fiber patch cords (or connectors, if you terminate your own fiber) only from 

a reputable supplier; low-quality components can cause many hard-to-diagnose 
problems in an installation. 

2.  Dust caps are installed at IMC Networks to ensure factory-clean optical devices.  

These protective caps should not be removed until the moment of connecting 
the fiber cable to the device.  Should it be necessary to disconnect the fiber 
device, reinstall the protective dust caps. 

3.  Store spare caps in a dust-free environment such as a sealed plastic bag or box 

so that when reinstalled they do not introduce any contamination to the optics. 

4.  If you suspect that the optics have been contaminated, alternate between 

blasting with clean, dry, compressed air and flushing with methanol to remove 
particles of dirt.
