摘要： A method of configuring an optical network terminal, ONT, of a wavelength division multiplexed passive optical network, WDM PON. Sequentially setting a transmission wavelength of a tunable optical filter at the ONT to one or more wavelengths of a pre-selected plurality of transmission wavelengths until a wavelength is identified for which no downstream optical signal from an optical line terminal of the WDM PON is detected. Determining whether a transmitter operable at said identified transmission wavelength is present at the OLT and is available to be assigned to communicate with the ONT. If a transmitter is determined to be present and available, maintaining the transmission wavelength of the tunable optical filter at transmission wavelength and assigning the ONT to the OLT as a subscriber at said identified transmission wavelength. If a transmitter is determined to be one of not present and not available, recommencing the method.

摘要： A method for negotiating speed between a Fiber Channel (FC) local client and a remote FC client across a DWDM network is provided. A transmission speed of the local FC client at a local ingress transport interface is detected. The data from the local FC client is forwarded along with the detected transmission speed to a remote egress transport interface. The remote egress interface forwards the data at the detected transmission speed to the remote FC client. The present invention eliminates complex speed negotiation state machines that would otherwise be required to make the DWDM transport behave like a virtual wire with respect to the FC ports and to allow the FC clients to negotiate the desired speed directly between themselves.

摘要： A supervisory channel is provided on an optical path (31) between nodes of an optical communication network. The nodes are arranged to use a set of wavelengths allocated for carrying traffic channels. An optical signal (16) which carries a supervisory channel is generated at a supervisory channel transmitter (15) and added (12) to the optical path (31) downstream of an optical amplifier (11). The optical signal (16) has a wavelength which is one of the set of wavelengths allocated for carrying traffic. The method is performed at a time when the wavelength is not being used to carry traffic. An impairment parameter of the received optical signal is measured at a supervisory channel receiver (15). The receiver is a coherent receiver and the impairment parameter is chromatic dispersion or polarization mode dispersion.
