We propose a new system of a continuous variable quantum key distribution via a wavelength router in the optical networks. A large bandwidth signal is generated by a soliton pulse propagating within the micro ring resonator, which is allowed to form the continuous wavelength with large tunable channel capacity. Two forms of soliton pulses are generated and localized, i.e. temporal and spatial solitons. The required information can be transmitted via the spatial soliton while the continuous variable quantum key distribution is formed by using the temporal one. This is formed by using an optical add/drop multiplexer incorporated in the optical network, where the localized soliton pulses are available for add/drop signals to/from the optical network. The high security and capacity information can be performed.
