In turn, this data rate requires aggressive performance metrics such as high transceiver bandwidth (BW) that is 2 times higher than the previous generation, low circuit noise, and low clock jitter. In addition, lower power consumption per bit is needed to fit into the optical module power envelop which is specified by multi-source
