Publication number: 20080226298Abstract: The present invention has been achieved to provide a novel optical transmission system realizing high-speed optical transmission over greater distance by suppressing waveform degradation caused by mode dispersion and mode transition in a multimode optical transmission line. The optical transmission system of the present invention includes: an optical transmitter for transmitting incoherent light; an excitation mechanism for exciting a predetermined mode in the incoherent light transmitted from the optical transmitter; a multimode optical transmission line for transmitting the incoherent light transmitted from the excitation mechanism; a transmission mechanism for transmitting a predetermined mode in the incoherent light transmitted from the excitation mechanism; and an optical receiver for receiving the incoherent light transmitted from the transmission mechanism or the incoherent light transmitted from the transmission mechanism.Type: ApplicationFiled: September 16, 2004Publication date: September 18, 2008Applicants: Nippon Telegraph and Telephone Corporation, NTT Electronics CorporationInventors: Hiroyuki Fukuyama, Toshihiro Itoh, Satoshi Tunashima, Kimikazu Sano, Koichi Murata, Yohtaro Umeda, Yasuo Tazoh, Hirohiko Sugahara, Hiromu Toba, Masahiro Muraguchi, Senichi Suzuki, Seiji Fukushima, Yoshinori Hibino, Tadashi Sakamoto, Yoshiaki Yamabayashi, Eiji Yoshida, Ryuichi Iwamoto

Patent number: 6587242Abstract: It is the object of the present invention to provide a transmission system that transmits a control signal corresponding to the overhead accommodating time division multiplexing information at a frequency that is the same (or nearly the same) as that of the main signal. In order to attain this object, an optical transmitter broadens in a time range the optical waveform of the OTDM signal having a wavelength &lgr;0 and the control light having a wavelength &lgr;1(≈&lgr;0), and multiplexes the signal light having an optical peak intensity set low compared to the OTDM signal peak intensity and sending this to an optical transmission fiber.Type: GrantFiled: October 22, 1999Date of Patent: July 1, 2003Assignee: Nippon Telegraph and Telephone CorporationInventors: Ippei Shake, Hidehiko Takara, Yoshiaki Yamabayashi, Osamu Kamatani, Koji Nonaka, Kentaro Uchiyama

Patent number: 6396601Abstract: An optical signal quality monitoring system is provided, by which the quality of optical signals can be examined using a single monitoring system, not depending on the bit rate of each signal. In the system, an optical signal having a bit rate N·f0, that is, N times as much as basic clock frequency f0, is sampled by using a pulse repetition frequency f0/n1−&Dgr;f or f0/n1+&Dgr;f where n1 is a predetermined natural number and the pulse repetition frequency slightly differs from f0/n1 by &Dgr;f, and an amplitude histogram of the optical signal is determined based on results of the sampling.Type: GrantFiled: December 1, 1998Date of Patent: May 28, 2002Assignee: Nippon Telegraph and Telephone CorporationInventors: Hidehiko Takara, Yoshiaki Yamabayashi, Ippei Shake

Publication number: 20010017866Abstract: In the present ultra-highspeed packet transfer ring network, an add/drop multiplex type node apparatus adds an optical packet to the optical fiber transmission path by preparing a label signal containing information on an address of a destination node apparatus or a routing to the destination node apparatus, and outputs time-sequenced signals to the optical fiber transmission path by multiplexing the optical packet and the label signal by means of wavelength or polarization multiplexing. The add/drop multiplex type node apparatus also receives a label signal by separating and extracting the label signal from the optical fiber transmission path, and determines whether to drop an optical packet corresponding to the label signal to its own node apparatus or to pass the optical packet through with reference to an address or routing information contained in the label signal, and operates an optical switch accordingly.Type: ApplicationFiled: February 28, 2001Publication date: August 30, 2001Inventors: Atsushi Takada, Jin Hun Park, Wataru Imajuku, Yoshiaki Yamabayashi

Patent number: 5995228Abstract: A first tunable wavelength pulse light source is driven by a reference signal to emit a first optical pulse. An optical demultiplexer demultiplexes a first optical pulse emitted from the first pulse light source into a reference optical pulse and an incident optical pulse to be sent into an object to be measured. An optical multiplexer multiplexes the reference optical pulse and an outgoing optical pulse passing through the object to output multiplexed light. A second pulse light source generates a second optical pulse which is synchronous with the first optical pulse and delays a predetermined time for each period of the first optical pulse. A sampling unit receives the multiplexed light and the second optical pulse to obtain an optical pulse train signal proportional to the intensity of the multiplexed light obtained in synchronism with the second optical pulse.Type: GrantFiled: February 16, 1999Date of Patent: November 30, 1999Assignees: Anritsu Corporation, Nippon Telegraph and Telephone CorporationInventors: Akihito Otani, Toshinobu Otsubo, Hidehiko Takara, Satoki Kawanishi, Yoshiaki Yamabayashi

Patent number: 5631896Abstract: A hitless path switching method without a bit loss. The same digital line signals on a working path and a protection path are continuously monitored independently for bit errors. If a bit error occurs in the working path and no bit error occurs in the protection path, a switching trigger is produced and a switching operation from the working path to the protection path is performed on a data block basis. Only correct data are transferred to downstream apparatuses. Reliable hitless switching is achieved not only in response to a failure in a path, but also in response to a bit error. Using data blocks of one frame length with an indicator for bit error checking placed at its beginning or top makes effective switching possible.Type: GrantFiled: July 17, 1995Date of Patent: May 20, 1997Assignee: Nippon Telegraph and Telephone CorporationInventors: Nobuyuki Kawase, Yoshiaki Yamabayashi, Yoshihiko Uematsu

Patent number: 5574717Abstract: In an optical transmission system applicable to a SDH network, communication between two line terminating equipments is performed in a form of a STM frame composed of a SOH field and a payload, which is determined by CCITT recommendations. The line terminating equipment provides a FEC circuit which is preferably arranged at a location between MSP and MST function blocks. The FEC circuit is designed to perform coding/decoding operations, using a cyclic Hamming code, directly on each AU-4 message derived from the STM frame. Otherwise, the FEC circuit performs operations on each k-bit interleaved AU-4 message (where `k` is an integer larger than 1). Check bits generated by a FEC coding circuit are written into undefined byte areas in a MSOH field, and error correcting is performed at a decoder circuit on the basis of embedded check bits, therefore FEC operations are performed within a multiplex-section layer.Type: GrantFiled: May 16, 1995Date of Patent: November 12, 1996Assignee: Nippon Telegraph and Telephone CorporationInventors: Masahito Tomizawa, Yoshiaki Yamabayashi, Yukio Kobayashi, Kiyoshi Nakagawa, Ken-ichi Yagisawa
