    Abstract: Disclosed herein is a muffler of a scroll compressor. The muffler includes a first muffler having a pair of chambers defined above an outlet of a fixed scroll to communicate with the outlet and a gas passage hole formed at the center of an upper end thereof, and a second muffler located around the first muffler to be spaced apart from the gas passage hole of the first muffler and having a chamber including one or more guidance paths of the fixed scroll. The muffler can achieve reduction of operational noise, sufficient separation of oil contained in discharge gas, and efficient isolation between a discharge pressure inside the muffler and outside suction pressure.

    Abstract: Disclosed is a method of registering only an authorized optical network terminal among a plurality of optical network terminals with the same serial number, in an optical line terminal, using a public key encryption algorithm, in a Gigabit Passive Optical Network (GPON). According to an exemplary aspect, a GPON system encrypts a physical layer OAM message transmitted/received for serial number registration of an optical network terminal, using a key distributed according to a public key encryption algorithm, and authenticates registration of the optical network terminal using the encrypted physical layer OAM message. Accordingly, it is possible to securely authenticate registration of an authorized optical network terminal and block registration of unauthorized optical network terminals.

    Abstract: A burst mode optical repeater is provided. The burst mode optical repeater receives optical signals, which are transmitted from a plurality of optical network units (ONUs) in a passive optical network (PON) to a central office using a time division multiplexing access (TDMA) method, and relays the received optical signals using an optical-electrical-optical (OEO) method. Since the burst mode optical repeater can be installed anywhere between an optical line terminal (OLT) and the ONUs, the number of subscribers and transmission range that can be supported by a corresponding network can be increased.
