940 nm Fiber Isolator

Chapter 2 Setup

2.1. Unpacking

Note: Thorlabs aligns the isolator with unpolarized light. This unit is fusion
spliced with the laser source fiber and individually tested. See the included test
report for details.

2.2. Installation Procedure

1) Carefully remove the unit from the box by removing the pins holding the
input and output fibers. Be wary of damaging the fiber when removing
the unit from the box.
2) Place the isolator into your fiber optic system.
3) Secure the base of the isolator to the table via the 4-40 (M3) mounting
slot.
4) Orient the isolator according to the engraving on the lid.
5) Splice the fiber to the source via fusion (recommended) or mechanical
splice.
6) Turn on the power source within the isolator wavelength range (±10 nm
of the center wavelength).
7) Ensure you apply only the maximum rated power of the isolator as
indicated on this spec sheet.
