Connecting the optical output
Figure 62 Trigger output circuit
The high and low voltage levels are defined by the following equations:
Vhigh = Vexternal
Vlow = Vexternal x 22k / (22k + R)
Connecting the optical output
Caution: Before connecting the optical output connector, ensure to check the
connector tip using a fiber microscope. Using the microscope, check for any de -
formities, damage, residue or other contaminants at the optical tip of the connec -
tor. Either clean the connector or contact NKT Photonics support if a replacement
is necessary.
The fiber and its connectors are inspected and sealed in a clean environment
before shipping. For optimum system performance, follow the guidance below:
•
Avoid removing any connector caps when the outputs are not in use and
kept in storage.
•
When connecting an output fiber, avoid:
•
Excessive strain on the fiber through stretching or twisting.
•
Fiber bend diameters < 10 cm
•
Exposing the fiber and its facets to contaminants.
•
Take good care and handle output fibers and their connectors gently to
prevent damage to the fiber or its facets.
