20 Maintenance and Calibration
20.1 Cleaning of Optical Interfaces
Interfaces must be kept clean. Special alcohol may be used to clean optic output. Always
replace protective dust caps when the unit is not being used, and keep the protective dust
caps clean.
In addition, flanges must be kept clean periodically.
20.2 Necessity of Cleaning
The diameter of optic core is 9 μm, and diameter of dust and other particulates ranges from
1/100 to 1/10 μm. Comparatively speaking, the size of dust and other particulates can cover
part of optic end and therefore degrade the performance of MTP-200.
In addition, power density may burn dust into optic fiber and induce further damage (for
example, 0dBm optic power may produce about 16,000,000W/m
2
power density in single
mode fiber). In this case, measurement will be inaccurate and irreversible.
20.3 Safety Instructions before Cleaning
1. Make sure MTP-200 is power off when cleaning
2. Any operations contradict to the instructions may result in dangerous laser
injuries.
3. Make sure laser source is off, when cleaning any optic connectors
4. When MTP-200 is in operation, please always avoid looking directly into
optic output. Although laser radiation is invisible, it may do serious injury to
eyesight.
