Description
12 Wavelength MWDM to Meet the 10km Link Budget
MWDM, short for Metro WDM, is a medium wavelength division multiplexing technology based on the 6 wavelengths of CWDM. MWDM compresses the 20nm wavelength spacing of CWDM into 7nm and employs Thermal Electronic Cooler (TEC) temperature control technology to split one wave into two, with a 3.5nm offset on the left and right sides, and expands to 12 wavelengths (1267.5, 1274.5, 1287.5, 1294.5, 1307.5, 1314.5, 1327.5, 1334.5, 1347.5, 1354.5, 1367.5, 1374.5nm) to meet the needs of operators. The first 8 wavelengths of MWDM use with DML+PIN+TEC, and the last 4 wavelengths use DML+APD+TEC to meet the 10km link budget. By leveraging existing CWDM infrastructure, MWDM achieves capacity enhancement while further conserving optical fiber resources.
MWDM is suitable for regional networks with medium-distance data transmission requirements, such as those connecting cities or multiple facilities within a large geographic area. Compared to the high capacity of DWDM and the simplicity of CWDM, MWDM strikes a balance between the two. MWDM combines the advantages of both, meeting the needs of medium-distance transmission without significantly increasing deployment cost, and is an economical and cost-efficient choice.
