 Please note: A few nJ (10 nW @ 1 s exposure) or even less are usually enough to achieve a measurement. Take special care when working with pulsed lasers to avoid exceeding damage threshold of optical fibers.

Suitable patchcords:

All laser spectrum analyzers feature FC/PC sockets.

For singlemode fibers: Use the  FC/APC connector at the
laser and the FC/PC  connector at the laser spectrum analyzer.

Your measurement results will be impaired when you apply
FC/APC connectors to a laser spectrum analyzer input.
