Methods, algorithms, architectures, circuits, andor systems for determining the status of parameters associated with optical transceiver operation are disclosed. The module comprises one or more cells stacked one on top of the other, each of these having at least one opening, the opening of the cell or the similar openings of the cells together forming at least one channel for feeding or discharging the fluid to be treated. Data packets that are accepted at the device are classified according to a set of defined classes and are transmitted through the device according to a policy for prioritization and bandwidth allocation for the classes. The foldable conductive oven provides convenience and practicability, because the invention is able to be folded or unfolded without any tools and easy to be carried or picked up.
