Abstract

With the large-scale commercial use of the global 5G network and the rapid growth of mobile Internet traffic

more abundant wireless spectrum resources can be released

and the demand for high-speed optical modules in wireless front-haul networks is increasingly prominent. Focusing on the key technologies of 50 Gbit/s front-haul optical modules

two main networking methods were deeply analyzed

the typical transmission distance and link loss were analyzed

the maximum and minimum dispersion values of coarse wave division multiplexing (CWDM) wavelengths in a 10 km scenario were explored

and the corresponding dispersion compensation strategies were studied. Through experiments

the changes in optical power penalty of different multi-path interference (MPI) were verified

and the potential impact of MPI noise on error performance was analyzed in detail. In addition

deep research on the optoelectronic chip scheme of 50 Gbit/s modules was conducted

the parameters of various types of optical modules were rigorously tested

standardized suggestions for the optoelectronic interface parameters of 50 Gbit/s front-haul modules were proposed

the current standard status of 50 Gbit/s modules at home and abroad was detailed

and the development trend of future applications was prospected.
