Table 20:
Using the protective glass
The cleaning steps differ depending on whether a protective conduit or
tube is used. For fiber connectors without quartz block protection or
with a protective conduit, the quartz-block end-face is cleaned; for fiber
connectors with protective glass, only the protective glass is cleaned, if
the quartz block end surface is free from debris. In case of persistent
dirt accumulation, the protective glass may be replaced with new pro-
tective glass.
Optional protective conduit
12.
Remove the screwed-on protective conduit and place it on a clean
surface. A clean, lint-free cloth is ideal for placing the protective
conduit on.
13.
Adjust the focus of the microscope to the quartz-block end-face.
