Similar to FDM, WDM (Wavelength Division Multiplexing) uses each wavelength of light to
transmit a signal. WDM is for fiber optic systems. The number of wavelengths per
fiber, currently available, is about 300. Each wavelength can carry about 10Gbps.
This makes 3Tbps. AT&T predict that up to 1024 wavelengths may be available in the future.

The hub/optical hub is clearly an analogue device - input signals are reflected to all
outputs. It is also called passive, because it does not introduce any power to the signal
