NextG’s Coarse Wavelength Division Multiplexing (CWDM) platform combines multiple RF signals from various service providers on laser beams at various wavelengths for transmission along fiber optic cables. NextG's CWDM can combine up to eight wavelengths onto a single fiber (16 wavelengths per fiber ring), spread out over a relatively large range of wavelengths. The NextG CWDM enables existing metro fiber rings to support multiplexing services onto a shared fiber backbone. This creates a system that is more flexible and cost effective than traditional architectures.

CWDM enables NextG to:

• Expand fiber distributed antenna systems in fiber-weak areas
• Offer ring-diversity on nodes connected to a NextG system
• Increase capacity in existing fiber distributed antenna systems
• Add bandwidth without large construction projects
• Support a less expensive, more flexible, more reliable DAS system
