Described by Google as a new Time and Wavelength Division Multiplexed Super PON (TWDM Super PON), the company believes that this new standard can reduce the network operating costs and investment costs. The company claims that the technology can do this by extending the transmission distance, which can reduce the number of central offices that need to deploy the optical line termination (OLT), significantly reducing equipment, space and power costs.
