iConverter 8878-31 Single-Fiber Course Wave Division Multiplexing (CWDM) module provides a flexible and cost effective solution for increasing fiber capacity over single fiber networks. CWDM over single-fiber increases network bandwidth capacity by enabling multiple wavelengths, or data channels that carry independent services over existing fiber infrastructure. Up to sixteen separate wavelengths can be transported on a single fiber link with iConverter Single-Fiber CWDM module.iConverter 8878-31 Single-Fiber Course Wave Division Multiplexing (CWDM) module provides a flexible and cost effective solution for increasing fiber capacity over single fiber networks.
