METHOD FOR THE TRANSMISSION OF A LOW-RATE SUPPLEMENTARY CHANNEL IN HIGH-RATE COHERENT OPTICAL TRANSMISSION SYSTEMS |
| 摘要 |
The invention relates to a method for the transmission of a low-rate supplementary channel (24) in high-rate coherent optical transmission systems for the transmission of supplemental data (26), in particular relating to the operation, in an optical communications link, in which a user data flow (17) in the form of a phase-modulated laser lightwave is transmitted, and and wherein syncbits (synchronization bits) are scattered into the user data flow (17) by a transmitter.
