摘要： Systems and methods for upgrading selected wavelengths in a WDM link to higher data rates at minimal expense are provided. Error correction coding techniques are employed such that the data encoded onto the upgraded wavelengths experiences higher coding gain than that experienced by data encoded on the non-upgraded wavelengths. This increases receiver sensitivity without the use of expensive opto-electronic components. In one embodiment, Reed-Solomon coding is employed on the upgraded wavelengths and no error correction coding is employed on the remaining wavelengths. These techniques may also be applied to new WDM links carrying channels with disparate bit rates.

摘要： There is described a method for enabling session mobility in a multi-participant IP-based multi-media communication network in full-mesh conference model, the method comprising: mapping a full-mesh communication protocol to a Session Initiation Protocol (SIP); defining an extended message protocol including new message mechanisms to support session mobility options; mapping the extended message protocol to the Session Initiation Protocol; and adding headers to mapped messages from the extended message protocol and from the full-mesh communication protocol to comply with full-mesh message signalization protocol mechanisms.

摘要： Highly efficient control of laser frequency is provided. An optical channel monitor is coupled to a composite WDM signal resulting from the multiplexing of outputs from multiple laser sources. The monitor determines the frequency of each laser and this measurement is used to provide feedback for laser frequency control. In this way a single optical channel monitor can provide frequency control for numerous WDM channels, greatly reducing the cost and space required. Monitoring capability may be provided to individual channels as needed.

摘要： A dithering signal is superimposed on a laser frequency control signal. In this way, laser frequency control may be achieved by employing measurements from a single photodetector. By sampling synchronously to the dithering signal, it is possible to generate both the magnitude end sign of the current frequency error based on the output of a single photodetector. This reduces the number of components required to generate an optical signal and is particularly advantageous in WDM systems where laser frequency control components may be duplicated over a large number of channels.
摘要翻译：抖动信号叠加在激光频率控制信号上。以这种方式，可以通过采用来自单个光电检测器的测量来实现激光频率控制。通过与抖动信号同步采样，可以基于单个光电检测器的输出同时产生当前频率误差的幅度结束符号。这减少了产生光信号所需的部件的数量，并且在其中激光频率控制部件可以在大量通道上复制的WDM系统中特别有利。
