This tool kit provides everything you need to measure power and provide a stable light source for fiber optic cable testing. The FPL-5050 Fiber Power Meter - Optical Light Source Kit (-50 to +26 dBm, single-mode) includes:

The FPM-50A Fiber Optic Power Meter to measure wavelengths from 800-1650 nm, with a mere 0.01 dB resolution
Measures 6 preset calibrated wavelengths with high precision to determine absolute or relative power
Includes FC/SC adapters for APC/PC/UPC connectors and an LC adapter for PC/UPC connectors only
The FLS-50 Fiber Optic Light Source to provide either 1310 nm or 1550 nm wavelengths for a stable light source for single-mode fiber measurements
Has four different modulation outputs (CW, 270 Hz, 1 kHz, 2 kHz) at 1310 nm and 1550 nm wavelengths
Includes FC, SC, and LC adapters to directly connect to UPC/PC FC, SC, and LC fiber connectors
