(a) Frequency response measured for short range (SR) scenario end-to-end link; (b) frequency response measured for the optical back-to-back of long range (LR) and extended range (ER) scenarios. Received electrical MultiCAP spectrum and corresponding constellations transmitted in each MultiCAP band for (c) short range (SR) scenario with total bit rate 70.4 Gbps; (d) short range (SR) scenario with total bit rate 80 Gbps; (e) long range (LR) and extended range (ER) scenarios with total bit rate 108 Gbps.
