Abstract: A communication method of an optical communication system in which a plurality of ONUs are connected to an OLT, includes steps (a) allocating, by the OLT, a transmission bandwidth to an ONU capable of an operation in a sleep mode in which an optical transmitter is tentatively halted for a predetermined sleep period, and transmitting a transmission bandwidth notification to the ONU when the ONU is in the sleep mode and when the ONU is not in the sleep mode; (b) receiving, from the ONU to which the transmission bandwidth is allocated, a response signal when the ONU is not in the sleep mode, wherein the response signal is or is not received during the sleep mode; and (c) suppressing, by the OLT, an alarm in the sleep mode, the alarm being caused by a communication failure with the ONU on a basis of the response signal not being received.

Abstract: An ONU includes the optical transceiver capable of an operation in a power-saving mode in which power consumption is reduced by stopping transmission while continuing reception, and a control device that controls to tentatively validate transmission of the optical transceiver and outputs a response signal when a control signal is received from an OLT during an operation in a power-saving state. Moreover, the OLT includes the control device that allocates a transmission bandwidth to the ONU even while the optical transceiver of the ONU operates in a power-saving mode and stops transmission and determines whether a communication failure occurs or the ONU is in operation in a power-saving mode based on the response signal received by a transceiver of the OLT.

Abstract: A laminate body (1) is provided with a transparent substrate (10) and a refractive layer (11) which refracts incident light towards the top of the substrate (10). The refractive layer (11) contains, at least, one kind of fluorine compound (ss) selected from a group consisting of fluoro-silsesquioxane and fluoro-silsesquioxane polymers, and a resin (pl) having a refractive index higher than that of the aforementioned fluorine compound (ss).

Abstract: The invention provides a test system of a fault detecting means, in which, during a normal operation, a fault forcibly generating circuit lets a transmission path signal inputted from the outside pass through as it is, generates a test signal which is the same as that of the transmission path signal, and outputs it to a fault detecting circuit. During a time of testing, the fault forcibly generating circuit outputs "Low" level of the test signal forcibly to the fault detecting circuit, according to a test control signal outputted from a control portion. When the fault detecting circuit detects this test signal, an step-out alarm is generated and transmitted to the control portion. The control portion monitors the step-out alarm from the fault detecting circuit. The control portion judges the operation to be normal if the step-out alarm is outputted, and to be abnormal if the step-out alarm is not outputted under the condition that the step-out alarm is not outputted at the time of non-testing.
