Modulation Index Study of a Cost-Effective Solution for CRAN Architecture Based on Coherent Radio-over-Fiber Backhaul
2018 11th International Symposium on Communication Systems …, 2018•ieeexplore.ieee.org
We study and experimentally evaluate the modulation index influence on Mach-Zehnder
Modulator in external modulation at low-radio frequency voltage (2.277 V pp) to improve the
system performance of a coherent receiver based-on 3× 3 coupler. The system achieves a
sensitivity of− 29 dBm in the error-free condition, after propagation through 60 km-long fiber
link at a frequency carrier of 15 GHz, offering a cost-effective solution for centralized radio
access network (C-RAN).
