The present invention provides an optical fiber preform manufacturing method and a burner apparatus employed for this method. The shoe midsole in the form of footprint plate comprising a light metallic skeleton in the form of footprint plate and RB ceramics or CRB ceramics molded around the skeleton. A client, such as a mobile wireless device, sends an instruction to perform the operation to a server. In some embodiments, plasma-enhanced atomic layer deposition may be utilized for the deposition, and may be conducted at a temperature suitable to anneal passivation materials so that such annealing occurs simultaneously with the plasma-enhanced atomic layer deposition. A pump impeller of the torque converter is fixed to the crankshaft, and a clutch for connection and disconnection of engine output is provided on the side of a transmission. According to the invention, a PON includes an optical splitter module having one or more optical couplers that combines downstream light from 1\xd7N optical splitter directing the output of an OLT and a cyclic AWG for transmission toward one or more ONUs.
