摘要： A method of assessing the feasibility of a composite optical path in an optical communications network in which the composite path is composed of two optical paths k1 and k2 is described. The method comprising the steps of defining, for each individual optical path k and with type i interface, at least one parameter indicating its feasibility, calculating a quality Q factor Q′_i,k1+k2 of the signal for the composite path, estimated considering the deterioration which affects transmission over the paths k1 and k2 and comparing this quality Q′_i,k1+k2 with a value Qbare_i which is defined as the lowest value which can be taken on by a mapping function Q_i(.) for interface i and which gives the Q factor as a function of the OSNR received evaluated under the conditions that are considered to be the worst case that can be accepted while ensuring the desired signal quality.

摘要： A peer network node, along with other peer network nodes, forms a higher-tiered optical network that transports wavelength division multiplexed traffic for multiple lower-tiered optical networks. The node comprises a plurality of dedicated bidirectional optical ports, including two or more lower-tiered ports and one or more peer ports. The node also comprises one or more hub-side bidirectional optical ports, and a switching circuit. The switching circuit is configured to distribute traffic received at the one or more hub-side ports to respective dedicated ports, for dedicated transport to one or more of the lower-tiered networks and peer network nodes. The switching circuit is also configured to direct any traffic received at the dedicated ports to the one or more hub-side ports for transport to a hub node, even if that traffic is actually destined for one of the lower-tiered networks to which a lower-tiered port is connected.

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.

摘要： A radio base station has a baseband controller coupled to a radio head by an optical wavelength division multiplexed link to pass downlink signals on a first wavelength, and uplink signals on another wavelength. A compensating delay is applied to one of the signals to compensate for a difference in transmission times between the downlink and the uplink signals. The compensating delay can be controlled according to the difference in wavelengths. By compensating for such differences in transmission times, synchronisation problems can be avoided or ameliorated, or transmission distances can be increased. This can result in more flexibility in choice of wavelengths, fiber types and fiber lengths, and greater resilience. This can enable simpler installation or configuration, or reconfiguration without needing to take care to restrict the selection of wavelengths on the WDM link or restrict the length of the link for example.
摘要翻译：无线基站具有基带控制器，其通过光波分复用链路与无线电头耦合，以传送第一波长的下行链路信号和另一波长的上行链路信号。对一个信号施加补偿延迟以补偿下行链路和上行链路信号之间的传输时间差。可以根据波长的差异来控制补偿延迟。通过补偿传输时间上的差异，可以避免或改善同步问题，或增加传输距离。这可以在选择波长，光纤类型和光纤长度以及更大的弹性方面产生更大的灵活性。这可以使得更简单的安装或配置或重新配置，而不需要注意限制WDM链路上的波长的选择或限制链路的长度。
