METHOD AND APPARATUS FOR ADJUSTING THE GAIN OF AN AMPLIFIER OF AN OPTICAL RECEIVER MODULE BASED ON LINK BIT ERROR RATE (BER) MEASUREMENTS

摘要

An open loop gain adjustment method and apparatus are provided for adjusting the gain of a TIA of an optical RX module based on measurements of the BER of the optical link in which the optical RX module is employed. The gain of the TIA is adjusted until a determination is made that a satisfactory or optimum link BER has been achieved.
