Deluxe Optical Power Meter with Memory
4.11 Connecting to the Optical Laser Source
When connected to the dual-wavelength laser source (FOLS-SM-200 or FOLS-
MM-200), the Optical Power Meter (FOPM-210) accurately measures loss at
distances up to 250 kilometers at 1550 nm. On-the-spot measurement will differ
with the working wavelength, fiber attenuation, and the testing environment.
