摘要： Disclosed are an environmental test chamber having a movable panel and a method of driving the same. The environmental test chamber is used in a thermo-hygrostat, a thermostat, and a high temperature-low temperature tester. The chamber body includes a test cavity in which an object is disposed. An air-conditioning unit conditions the air inside the test cavity, thereby controlling a condition of the test cavity. A movable panel is accommodated in the chamber body to decrease or increase a volume of the test cavity. The efficiency of the chamber is enhanced, and the cost and space required for installing additional equipment is reduced.

摘要： Disclosed are an optical transmission apparatus and method in a wavelength division multiplexing passive optical network (WDM-PON). The optical transmission apparatus outputs an optical signal by applying a DC bias current and an RF signal to a laser diode at a threshold current level of the laser diode, thereby broadening an optical spectrum of the laser diode. Accordingly, an optical link becomes less vulnerable to reflection induced noise, which contributes to improve stability and reliability of the optical link.

摘要： 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.

摘要： An optical waveguide device and an optical communication module are provided. In the optical waveguide device which includes a core and a cladding layer formed around the core and has one end formed to be inclined so as to refract input and output signals, the core includes therein a diffraction portion for diffracting an optical signal incident through the cladding layer to propagate straight through the core. Thus, it is possible to prevent deterioration of an optical signal coupling ratio in implementing a technique of transmitting optical signals in opposite directions.

摘要： A fragmentation repetition detection apparatus (410) for detecting an IP fragmentation repetition which may occur in a multicast or unicast environment is provided. The fragmentation repetition detection apparatus (410) includes a packet capturing unit (411) which captures a received packet, a fragmentation repetition detector which detects whether or not the captured packet is a packet which is repetitively fragmented, and a path maximum transmission unit (PMTU) transmitter (414) which transmits PMTU information acquired by the fragmentation repetition detector (412) to a server which transmits the packet when the captured packet is a packet which is repetitively fragmented. Since a packet is transmitted by readjusting a PMTU, a fragmentation of an IP packet can be prevented.
