Provided is a WDM-PON system based on a wavelength-tunable ECL. A method of controlling an upstream optical wavelength of an ONT in WDM-PON system, the method comprises: determining upstream optical wavelength information of the ONT corresponding to a downstream optical wavelength predetermined to the ONT newly installed by being connected to a network; in an OLT, loading the determined upstream optical wavelength information onto the downstream optical wavelength assigned to the ONT and transmitting the loaded upstream optical wavelength information to the ONT; in the ONT, generating an upstream optical wavelength based on the upstream optical wavelength information transmitted by being loaded on the downstream optical wavelength from the OLT; and in the ONT, loading upstream data onto the generated upstream optical wavelength and transmitting the loaded upstream data to the OLT.

The skin preparation device and sensor of the present invention include an array of rigid tines. The tines serve to “self-prepare” the skin at each electrode site. These tines, when pressed against the skin, penetrate the stratum corneum, thereby reducing skin impedance and improving signal quality. A self-prepping device of the present invention is an optimized array of short non-conductive rigid tines in which the individual tines are created in a geometry that allows for a sharp point at the tip when molding, machining or etching is used as a method of fabrication. This non-conductive array with rigid penetrating structures may, therefore, be used in combination with a conductive medium, preferably an ionic conductive gel. In penetrating the stratum corneum, micro-conduits are created in the layers of the skin enabling the conductive medium to reach the low impedance layers and to transmit bioelectrical signals from the skin to the electrode surface. Such a self-prepping device can be readily mass produced using molding methods or possibly other manufacturing methods, thereby providing for a low cost means of achieving improved performance of the biopotential sensor. Additionally this invention includes the integration of this self-prepping device into a biopotential sensor comprising an array of one or more electrodes.
