20110211840 | REMOTELY SETTABLE CHROMATIC DISPERSION ROBUSTNESS FOR DENSE WAVE DIVISION MULTIPLEXING INTERFACES - An apparatus for transmitting signals in a telecommunications network includes a light source that generates an optical signal for encoding information transmitted from the apparatus over a light path of the telecommunications network, a modulator configured for controlling the optical signal to generate chirped optical pulses of the optical signal, the chirped optical pulses having a first frequency spectrum controlled by the modulator, such that when the pulses are transmitted from the apparatus and received at an end of the first light path the pulses have a chromatic dispersion penalty that is less than a predetermined penalty. Modulation control circuitry receives instructions from a remote controller and, in response to the instructions, controls the modulator such that the chirped optical pulses have a second frequency spectrum controlled by the modulator, such that when the pulses are transmitted from the apparatus and received at an end of a second light path of the telecommunications network the pulses have a chromatic dispersion penalty that is less than a predetermined penalty. | 09-01-2011 |
20140133653 | Timeslot Encryption in an Optical Transport Network - An Optical Transport Network (OTN) frame comprises an optical channel payload unit that is divided into a plurality of timeslots. This OTN frame is received at a transmitter and the timeslots are grouped into blocks of timeslots. Two or more blocks of timeslots are selected for encryption and are encrypted/authenticated in parallel to generate an encrypted OTN frame in which only certain blocks of timeslots are encrypted. | 05-15-2014 |

20120158990 | Transporting a CBR Data Stream Over a Packet Switched Network - In one embodiment a method includes receiving a constant bit rate data stream, segmenting the constant bit rate data stream into fixed size blocks of data, generating a time stamp indicative of a system reference clock, the time stamp being in reference to a clock rate of the constant bit rate data stream, encapsulating, in an electronic communication protocol frame, a predetermined number of fixed blocks of data along with (i) a control word indicative of, at least, a relative sequence of the predetermined number of fixed blocks of data in the constant bit rate stream and (ii) the time stamp, and transmitting the electronic communication protocol frame to a packet switched network. | 06-21-2012 |
20130148965 | MULTIPROTOCOL TRANSPORT USING POLARIZATION DIVISION MULTIPLEXING - Using polarization modulation techniques to simultaneously transmit two different data streams (formatted according to two different protocols) over a single optical wavelength. A first data stream that is encapsulated for transport using a first transport protocol, and a second data stream that is encapsulated for transport using a second transport protocol are received. The first data stream is modulated on a wavelength with a first polarization mode of a polarization division modulation scheme to produce a first modulated data stream and the second data stream is modulated on the wavelength with a second polarization mode of the polarization division multiplex transmission scheme to produce a second modulated data stream having the second polarization mode. The second polarization mode is orthogonal to the first polarization mode. The first and second data streams are combined onto a single wavelength for transmission over a single optical fiber using a polarization beam combiner. | 06-13-2013 |
20140064722 | Optical Transport Network Delay Measurement - In one embodiment, a one-way delay is measured between optical devices in an optical transport network based on roundtrip times of request and corresponding response frames. A first optical device sends a sequence of delay measurement request frames to a second optical device, which varies a local delay before responding to a request frame, thus causing a slippage in the sequence of reply frames received by the first device. The point at which the request frames are received in relation to the stream of frames sent by the optical device can be identified based on the frame slippage. Therefore, the delay measurement can be adjusted by a corresponding offset to the beginning of a frame in order to increase the accuracy of the one-way delay measurement. | 03-06-2014 |
20140362989 | Securing Virtual Lane Physical Layers - A data stream with a given data rate is distributed into a plurality of virtual lanes or streams, each with a lower data rate than the data stream. Virtual lanes permit the use of lower cost electronics at the optical-electrical conversion points. Security information is generated that includes a unique initialization vector. The security information is distributed or allocated across some or all of the of the virtual data streams in a virtual lane alignment marker in a portion of the alignment marker used to maintain direct current (DC) transmission balance, but that otherwise does not provide useful information. | 12-11-2014 |
