The power meter is meant to meet the high demands of fiber optic testing. It can be used for the absolute power measurement and relative measurement of the link loss in dB. Its compact size, user friendly interface, broad power measurement range, and precision makes it a high performance testing device ideal for network testing. Different style adapter caps are included. Also included on the 2nd port, a 1mW Visual Fault Locator allows for quick and easy troubleshooting and continuity testing.
