How many dB is the attenuation of a beam splitter

How many dB is the attenuation of a beam splitter

If we have measured gains in linear units (e. in Watts – W), the loss value in dB is calculated by the formula: Loss (dB) = 10 lg ( mW1 / mW2 ) When both gains are equal, the loss is 0 dB, so there is no loss (doesn't happen obviously). If we operate with absolute gains measured in relation to 1. They are used to divide a beam of light into two or more separate beams.
