摘要： Consistent with the present disclosure, an optical communication system, such as a passive optical network (PON), is provided that includes an optical line terminal (OLT) and a plurality of optical network units (ONUs). The OLT includes a plurality of photonic integrated circuits that have both optical transmitters and receivers provided therein. Accordingly, the OLT may have fewer components and a simpler, more reliable and cost-effective design than a conventional OLT including discrete components. In addition, various ONU configurations are provided that also have a simple design and fewer components. Thus, ONUs consistent with the present disclosure may also have reduced costs.

摘要： A node, of a group of nodes, may detect a failure on a first path; establish a connection associated with a second path when the failure on the first path is detected; store an identifier in a field in an overhead portion of a data frame when the failure on the first path is detected, the data frame including a payload portion that contains a client signal, the identifier instructing another one of the nodes to establish a connection associated with the second path; and transmit the data frame to the other one of the nodes via the second path.

摘要： The present invention provides a system, apparatus and method for accurately identifying optical or digital impairments on a span using FEC errors identified at an intermediary node. This information may be provided to an end node within a network to switch to a redundant path around the impaired optical path or span therein. In one embodiment of the invention, signal degradation is identified by analyzing FEC data within a FEC decoded signal at an intermediary node. An identification of signal degradation provides an indication of a potential failing span within an optical link, which may be provided in-band or out-of-band to a terminal node so that a signal may be switched around a failing path, or span therein, prior to an actual failure event.

摘要： A system, apparatus and method are described for displaying multiple attributes relative to objects in a network management program. In one embodiment, multiple attributes from a plurality of different standards are coalesced together and the coalesced attributes are displayed by a user interface. These coalesced attributes may be shown in such a manner so that inconsistencies between attributes of objects from different standards are reduced or obviated.
摘要翻译： 描述了一种用于显示关于网络管理程序中的对象的多个属性的系统，装置和方法。 在一个实施例中，来自多个不同标准的多个属性被合并在一起，并且合并的属性由用户界面显示。 这些合并的属性可以以这样的方式示出，使得来自不同标准的对象的属性之间的不一致性被减少或消除。
