摘要： A Reflective Semiconductor Optical Amplifier (RSOA) for compensating for light loss in an optical link, an RSOA module for improving polarization dependency using the RSOA, and a Passive Optical Network (PON) for increasing economical efficiency and practical use of a bandwidth using the RSOA are provided. The PON includes a central office comprising a plurality of optic sources transmitting a downstream signal and a plurality of first receivers receiving an upstream signal; at least one optical network terminal (ONT) including a second receiver receiving the downstream signal and an RSOA which receives the downstream signal, remodulates the downstream signal into the upstream signal, and transmits the upstream signal in loopback mode; and a remote node interfacing the central office with the ONT. The upstream signal and the downstream signal are transmitted between the remote node and the ONT via a single optical fiber. The remote node includes an optical power splitter at its port connected to the ONT.

摘要： Disclosed is a method for preparing metal nanoparticles, the method comprising the steps of: providing a solution of metal salt and a solution of a strong reducing agent with a standard reduction potential of −0.23V or lower; and mixing the solutions by using a micro mixer without supplying additional heat energy from the exterior, while carrying out reduction of the metal. Metal nanoparticles obtained by the above method, and a micro mixer for preparing the metal nanoparticles are also disclosed. The method for preparing metal nanoparticles via the reduction of metal ions in a solution uses a strong reducing agent and a micro mixer. Therefore, it is possible to obtain metal nanoparticles having a particle size of 20 nm or more and a uniform shape and dimension without supplying additional heat energy from the exterior. Additionally, the method is amenable to a continuous process, and thus ensures cost-efficiency and stable product quality required for mass production.

摘要： A ventilating apparatus, a heat exchange apparatus, a heat exchange element, and a rib therefor are provided. The heat exchange element includes a plurality of heat exchange sheets which are multi-stacked, and a plurality of ribs arranged between the heat exchange sheets to form ducts with the heat exchange sheets. Each of the plurality of ribs includes an irregular structural surface including an uneven portion. The uneven portion may include a recess portion, a protrusion portion, or a combination of a recess portion and a protrusion portion, which generates a turbulent flow in a heat exchange gas flowing through the duct. Such heat exchange element having such a rib may minimize duct resistance by suppressing a laminar flow and growth of a boundary layer in airflow of outdoor and indoor air passing through a heat exchanger, and may further increase heat exchange efficiency because the heat exchange gas may be introduced/exhausted smoothly at a low flow velocity.
