WebFiber optics has been providing long distance connections for a long time. But, until now, the higher cost often made it impractical in many LAN topologies. That is has been changing as the need for bandwidth rises and the price of fiber drops. WebSo, the power of 20 dBm is equal to 100 mW or 0.1 W (Watt). Example 2: Convert -30 dBm to milliwatts: P (mW) = 10 (-30/10) = 0.001 mW. So, the power of -30 dBm is equal to 0.001 mW or 0.000001 W = 1 μW.
