Understanding CWDM Wavelength Allocation in 100G IR4 Modules
As 100G connectivity becomes standard across enterprise and metro-access networks, 100G IR4 modules have emerged as a cost-effective solution for reaches up to 2 km over single-mode fiber (SMF). At the heart of the 100G IR4 design is CWDM-based wavelength allocation, which enables four parallel 25G optical lanes to coexist on a single fiber pair….
