5G fronthaul bearer solution based on CWDM and circulator technology

Time:2022-03-24 Views:146
USource circulator realizes 12-channel bidirectional transmission of CWDM 1271nm to 1371nm 6 wavelengths.

Deploying three 5G base stations in most areas can meet the demand, each base station has 1 transmit and 1 receive, a total of 6 wavelengths, and the relatively low-cost CWDM 1271-1371 color light 25G SFP optical module is used.
5G fronthaul CWDM SOLUTION
In areas with relatively large population density, 6 base stations need to be deployed. The conventional 5G fronthaul system uses passive wavelength division of 1271-1371nm 6 wavelengths plus 1471-1571nm 6 wavelengths, a total of 12 waves of CWDM 25G SFP28 modules, but the cost of 1471-1571nm optical modules using EML lasers is high. In order to solve this problem, USource has launched a circulator for 5G fronthaul applications, which realizes 12-channel bidirectional communication based on 1271-1371nm 6-wavelength, thus avoiding the use of relatively high-cost 1471-1571nm SFP modules.
