Optical packet transmisson

摘要

A burst mode optical signal (OPAK) is transported as payload of a framed continuous bit-stream optical signal (OCON) through an optical transport network (OTN). The optical bursts (OPAK) are all generated at a common nominal bitrate which equals substantially the payload bitrate of the continuous bit-stream optical signal (OCON). The bursts are converted into a continuous bit stream by filling gaps between the bursts with a predefined pattern. The continuous bit stream thus created is then mapped into frames to generate the framed continuous bit-stream optical signal (OCON) for transmission. <IMAGE>
