The FOA Reference For Fiber Optics
Optical power, required for measuring source power, receiver power and, when used with a test source, loss or attenuation, is the most important parameter and is

This level of testing consists of link attenuation testing, link length, and a pola ity check. Typical power levels measured by an optical power meter: Telecom transmitters: 0 to +10 dBm (1 to 10 milliwatts), Receivers: -30 dBm (1 microwatt) DWDM systems with fiber amplifiers: +10 to +20 dBm (10 to 100 milliwatts), Receivers: -20 to -30 dBm (1-10 microwatt) Data links and LANs: 0 to -10 dBm. To use a power meter for fiber optic testing, always clean connectors first with lint-free wipes or click-to-clean tools. From fig(c) measure the value of output intensity (Iout) of the light at different angles and begin from θ=0.
