A radio frequency output power control system for use in communication systems is disclosed. A first mask having a first pattern is applied over surface of an n-type layer. The MPE creates and rearranges BIDIRs based upon volume thresholds of traffic being reached in BIDIRs, such as by splitting overloaded BIDIRs. A silver comprising layer is formed over the chalcogenide material. The fixture may be configured to disconnect the power source upon removal of a face plate of the fixture.
