摘要： An optical transmission network is inherently asynchronous due to the utilization of a variable overhead ratio (V-OHR). The network architecture makes extensive use of OEO regeneration, i.e., deals with any electronic reconditioning to correct for transmission impairments, such as, for example, FEC encoding, decoding and re-encoding, signal reshaping, retiming as well as signal regeneration. The optical transmission network includes a plesiochronous clocking system with intermediate nodes designed to operate asynchronously with a single local frequency clock without complicated network synchronization schemes employing high cost clocking devices such as phase locked loop (PLL) control with crystal oscillators and other expensive system components. The asynchronous network operation provides for asynchronous remapping or remapping of any client signal utilizing any type of transmission protocol where the line side rate or frequency is always the same frequency for the payload signal and the local frequency at an intermediate node is set to a local reference clock in accordance with the payload type and its overhead ratio, i.e., the overhead ratio is varied to meet the desired difference between the line rate or frequency and the desired client signal payload rate or frequency for the particular client signal payload type.

摘要： A transmission network includes network elements which accept client signals to be transported over a transmission network, particularly an optical transmission network, each of the client signals having one of a plurality of payload rates. The client signals are digitally mapped into first transport frames and, subsequently, digitally mapped into second transport frames for transport across the network infrastructure. The second transport frames having a universal frame rate throughout the transmission network infrastructure supporting a client signal of any frequency, whether the client signal includes a standard client payload or a proprietary client payload.

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.
