Chapter 8: Fiber Optic Cleaning & ESD Precautions
8. Fiber Optic Cleaning Guidelines
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;
2.Dust caps are installed at Black Box to ensure
3.Store spare caps in a
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.
Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product,
1.Do not remove unit from its protective packaging until ready to install.
2.Wear an ESD wrist grounding strap before handling any module or component. If the wrist strap is not available, maintain grounded contact with the system unit throughout any procedure requiring ESD protection.
3.Hold the units by the edges; do not touch the electronic components or gold connectors.
4.After removal, always place the boards on a grounded,
WARNING! Integrated circuits and fiber optic components are extremely susceptible to electrostatic discharge damage. Do not handle these components directly unless you are a qualified service technician and use tools and techniques that conform to accepted industry practices.
