Appendix: Optical fiber loss measurement Step 1- Optical Reference Level Turn on optical power meter and press the λ key to select the wavelength. Turn on optical light source and select the wavelength. Wait for 1-2 minutes until it stabilize. Select a piece of patch cords, which is used to connect with the light source. The patch cords must be the same fiber type as the fiber under test. Connect the light source with the Power Meter through the source patch cords.

CARE OF YOUR INSTRUMENT 1. Always clean the mating connector tip and ferrule before mating, using approved materials. Clean the instrument using alcohol or other non solvent cleaning agents. Acetone or other active solvents may damage the case. 2. When not in use, keep connectors covered and away from dust. Dust and other particles, however, can range from tenths to hundredths of microns in diameter.
