FLS-50 FO Light Source

This FO optical light is designed to provide either 1310 nm or 1550 nm wavelengths. This FO optical light sourcePRODUCT DATA SHEET PDF.
is the perfect tool for providing a stable light source for single mode fiber measurements. See  also new multi-mode
& Single-mode Fiber Optic Light Source FLS-55.USER MANUAL PDF.

FLS-50 – FO Light Source provides two different wavelength outputs, 1310 nm or 1550 nm, at
varying frequencies for checking the optimal loss of single mode fiber optic cables using our FPM-50
Fiber Optic Power Meter (or other power meters).

The FLS-50 FO Light Source is designed for optimal use with our FPM-50 Optical Power Meter for measuring
optical loss on both single mode and multimode fiber cable. Note that the LC adapter may have up to
0.3 dB of signal loss.
