Abstract
The 5G fronthaul optical modules are the basic building block of the 5G network and WDM solutions are desired. Application code of MWDM has just been defined in ITU SG15 in December 2021 and are currently under intense study, naming draft recommendation G.owdm2. We organized the investigation and evaluation of MWDM optical modules from different vendors. Key parameters of optical/electrical interface have been tested and analyzed, including wavelength deviation, 20dB bandwidth, total mean output power, optical sensitivity, optical path penalty, eye diagram, power consumption as well as DDM function. Current commercial 25G MWDM optical modules are demonstrated capable to support transmission in O band covering almost all scenarios of 5G fronthaul.
