FPM-50A Fiber Optic Power Meter (-50 to +26 dBm) with FC/SC/LC Adapters


The Jonard Tools Fiber Optic Power Meter is perfect for measuring both the absolute optical power and relative power loss in fiber optic cables.

Measures a wide variety of 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. Special function of the unit allows the device to be manually calibrated as needed. LED screen is backlit for viewing in low light locations and a 10 minute auto-off helps preserve battery life. Dust-proof button design and shatter-resistant sleeve protect the tool to last a lifetime. Comes with FC, SC, and LC adapters so that fiber connectors can be directly connected to the tool (FC/SC adapters are for APC/PC/UPC connectors and LC adapter is for PC/UPC connectors only).
