When limited by available fibers Fosco carries Singlemode fiber WDM SFP modules. These SFPs transmit and receive over the same fiber using Wavelength Division Multiplexing (WDM) fiber optic technology. These SFPs utilize two different light sources (LASER) to achieve full duplex transmission over a single fiber minimizing fiber usage.
