摘要： An optical switching system is implemented by providing a transmitting section with a preparatory transmitted optical signal selector and a working transmitted optical signal splitter, which are each implemented by a 1×2 optical space switch, and by providing a receiving section with a receiving optical switch which is implemented by a 2×2 optical space switch, and with a preparatory receiving optical gate which is implemented by a 1×2 optical space switch. This makes it possible to switch between the working system and preparatory system without employing any 4×4 optical space switch, thereby implementing a practical optical switching system without causing such problems as communication interruption during maintenance or impairment of transmission path working efficiency.

摘要： A bilateral optical transmission system for pulse information disclosed which can accommodate variations in the relationship between the down-link signal transmission rate and the up-link one. A single bilateral optical transmission line is laid between first and second positions. A transmission pulse train with pulse transmission time slots set therein at fixed time intervals is provided onto the transmission line from the first position. A return pulse train is retransmitted from the second position to the first position over the bilateral optical transmission line. The return pulse train is obtained by gating the transmission pulse train with up-link information pulses from the second position to the first position in synchronization with up-link pulse transmission time slots for the transmission of the up-link information pulses so that at least one predetermined transmission time slot in each unit transmission period defined by a predetermined number of pulse periods in the transmission pulse train is used as the up-link pulse transmission time slot. At the first position, at least one time slot other than the up-link pulse transmission time slot in each unit transmission period is used as at least one down-link pulse transmission time slot for the transmission of down-link information pulses from the first position to the second position.

摘要： A system for measuring laser spectrum is disclosed in which the laser light to be measured is branched into one branched light and the other branched light so that the laser spectrum of the light is measured from a beat output resulting from mixing a delayed light obtained by delaying the one branched light for a certain period of time with the other branched light undelayed. In accordance with the present invention, the delay time of the delayed light undergoes such variations as to assume a value equal to an integral multiple of a fixed delay time by the use of an optical directional coupler.

摘要： An optical switch for switching laser beams, having a transparent glass plate with a reflection film on the surface of the same has been found. When the reflection film is at the first position, the first input beam is coupled with the output beam through the transparent glass plate, while the second input beam is prevented by said reflection film. When the reflection film is at the second position, the first input beam is prevented by said reflection film, and the second input beam is coupled with the output beam through the reflection by said reflection film. Thus, according to the displacement of the transparent glass plate together with the reflection film, the input beams are switched. Due to the above operational principle, the output optical level does not decrease even during the transient time, and then, the present optical switch is utilized in an optical repeater for digital communication.

摘要： A mobile dual-stack node engages in IPv6 communication while roaming within an IPv4-only network. The node determines that it has moved and obtains a new IPv4 address. After determining that the visited network contains no IPv6-enabled components, the node communicates with a tunnel broker to obtain a care-of address and a tunnel to an IPv6 connect agent (e.g., a tunnel server). If the obtained care-of address differs from the care-of address that the node had been using prior to the move, the node sends MIPv6 binding updates to its home agent and corresponding peers. The node can optimize the handoff when it has obtained a different care-of address by sending a binding update to the connect agent comprising the previous care-of address and the current care-of address. When the connect agent receives a packet destined for the previous care-of address, it forwards the packet to the current care-of address.

摘要： In a light source for generating light containing multiple wavelengths substantially uniform in intensity, a wavelength demultiplexing element 10 (for example, waveguide-type wavelength selecting filter) demultiplexes input light into a plurality of wavelengths &lgr;1 through &lgr;32. Optical amplifiers 14-1 through 14-32 amplify outputs of the element 10 and applies them to input ports of a wavelength multiplexing element 12. The wavelength multiplexing element 12 wavelength-multiplexes their input. Output of the wavelength multiplexing element 12 is applied to a fiber coupler 16 which, in turn, applies one of its outputs to the wavelength demultiplexing element 10. The optical amplifiers 14 have a gain larger by approximately 10 dB than the loss in the optical loop made of the element 10, optical amplifier 14, element 12 and fiber coupler 16. The other output of the fiber coupler 16 is wavelength-multiplex light containing wavelengths &lgr;1 through &lgr;32.

摘要： To enable the surveillance of a long-distance optical fiber line that a method using the reflection lights and Rayleigh backscatter lights cannot cover, a plurality of optical reflection elements P1-Pn are interposed in the optical fiber line at each specific distance. Each of the optical reflection elements P1-Pn reflects only a light signal of one of specific wavelengths .lambda.1-.lambda.n on a constant level. Light pulses of the specific wavelengths .lambda.1-.lambda.n are transmitted to the optical fiber line to measure intensities of the light pulses reflected by the optical reflection elements P1-Pn. From the measurement, surveillance of the optical fiber line can be done between the transmitter and each of positions of the optical reflection elements P1-Pn. The reflectance of the optical reflection elements P1-Pn can be set to 100%, and the surveillance becomes possible even if the length of the optical fiber line exceeds 200 km.
