摘要： An optical communications system using forward error correction (FEC) to correct errors in signals carried by the system. Optical signals on the system are dropped at nodes and converted to electrical signals by avalanche photodiodes (APDs) at the node receivers. An FEC chip operates on the electrical signal to correct errors. The error rate is used to control the APD bias voltage which affects signal noise and therefore error rate. The errors in a predetermined interval are counted and a determination made as to whether the error rate is rising with time. The bias voltage is derived from the value of a counter whose count is incremented each interval. If the error rate is rising, the counting direction is changed.

摘要： An object of the invention is to realize a gain monitoring method for an optical amplifier and an apparatus thereof, capable of detecting a gain for a signal light regardless of a noise light generated inside the optical amplifier. To this end, in the gain monitoring method according to the present invention, a part of a signal light input to an optical amplifier is branched as an input monitor light, and the input monitor light is modulated, and also a part of a light output from the optical amplifier is branched as an output monitor light, so that the modulated input monitor light and the output monitor light are multiplexed. Then, the multiplexed light is converted into an electrical signal, an interference component contained in the electrical signal is extracted, and a gain for the signal light in the optical amplifier is detected based on the interference component.

摘要： An add/drop arrangement using broadband optical couplers provides a low-loss, highly flexible add/drop capability for survivable wavelength division multiplexed (WDM) ring networks. At each node in the ring having the broadband optical coupler-based add/drop element, a portion of optical signal power of the entire WDM signal (i.e., all optical channels) is tapped off so that one or more optical channels of particular wavelengths can be dropped at the node. Information (e.g., data) to be added at the node is supplied in an optical channel that is added to the WDM signal via the broadband coupler. Because the add/drop element uses a broadband coupler, another portion of optical signal power of the WDM signal, including any added optical channels, passes through the node onto the ring. Depending on the specific ring topology being used with the broadband coupler-based add/drop arrangement, additional wavelength assignment and handling measures may be required. For example, certain ring topologies may experience interference between optical channels of particular wavelengths due to possible re-circulation of these optical channels beyond the add and drop nodes (e.g., after an optical channel passes its destination node). According to one illustrative embodiment, a node is equipped to perform wavelength conversion and/or wavelength suppression to prevent undesirable re-circulation of optical channels.
摘要翻译：使用宽带光耦合器的添加/删除装置为生存波分复用（WDM）环网提供了低损耗，高灵活性的分插能力。在具有基于宽带光耦合器的分插元件的环中的每个节点处，整个WDM信号（即，所有光信道）的光信号功率的一部分被分接，使得特定波长的一个或多个光信道可以被丢弃在节点。在节点处添加的信息（例如，数据）经由宽带耦合器被添加到WDM信号的光信道中。因为加/减元件使用宽带耦合器，WDM信号的光信号功率的另一部分（包括任何附加的光信道）通过节点到达环。根据与基于宽带耦合器的分插配置一起使用的特定环形拓扑，可能需要额外的波长分配和处理措施。例如，由于这些光信道可能重新循环超过加和落节点（例如，在光信道通过其目的地节点之后），某些环形拓扑可能会遇到特定波长的光信道之间的干扰。根据一个说明性实施例，节点被配备为执行波长转换和/或波长抑制以防止不希望的光通道重新循环。
