A low-loss shared FTTH distribution network that enables optical communications within a subscriber area, including optical fibers routed from a point of distribution to the subscriber area, a tap device including an optical tap which interfaces a downstream optical fiber with a first optical fiber, and a straight-through optical fiber which is routed straight through the tap device. The laser processing apparatus includes a laser processing head having a transmission window, an opening portion, an outlet hole, a first vent hole and a second vent hole. Each mobile printer prints data based on information input to the corresponding data input terminal. The solar cells are wired to a DC electric motor so that the motor rotationally responds to the disparity in the power output of the solar cells. The airflow director adjacent to the moisture removal component extends in a plane that is generally parallel to the first direction. The novel endotracheal tube apparatus enables the application of continuous suction or intermittent suction.
