Optical interface
Optical interface
The laser has two optical outputs on the front panel. The optical outputs are assigned
as:
•
Main – this is the laser’s primary optical output (Class 3B or Class 4) near
which, a laser aperture label is affixed.
– or –
•
Monitor – this is a low power output intended for monitoring purpose only.
The output is classified as a laser CLASS 1 and therefore it does not require a
laser aperture label.
Contact NKTP support for information on how the laser’s optical ports are assigned.
See
“Support contact details” on page 104
.
Optical fibers,
connectors and
adapters
The optical outputs can be configured as either:
•
fiber patch cords with FC/APC connectors (FC/APC pig-tail)
– or –
•
connector adapters (FC/APC adapter or SC/APC adapter)
Polarization maintaining output
The output fiber of the laser is polarization maintaining, the slow axis is by default
aligned to the connector key. Because of this, the laser polarization (E-field) is parallel
to the key.
