... amplified optically (e.g., with an erbium-doped fiber amplifier [EDFA]) to a fairly high power level and then is detected with a passive low-impedance front-end. For example, given an amplified optical ... bound for the BER (or a lower bound for Q). Furthermore, the accuracy of the relationship depends on how well the random jitter follows a Gaussian distribution. With Eq....
