What is a normal signal strength dBm for an optical module
An Excellent/Ideal signal strength generally falls between -15 dBm and -25 dBm, though some systems may operate well up to -8 dBm. This range ensures the ONT receives a strong, clean signal without overwhelming the device's receiver. Optical loss is measured in “dB” which is a relative measurement, while absolute optical power is measured in “dBm,” which is dB relative to 1mw optical power Loss is a negative number (like –3. 2 dB) while power measurements can be either positive (greater than the reference) or negative (less than. , The single-mode optical module has a receiving power range of -23 dBm to 0 dBm.
