<p>A method for transparent transmitting 10GE Ethernet signal through the optical transport network is disclosed, the method uses the first asynchronous mapping manner for transparent transmitting 10GE Ethernet signal; wherein, the construction of the first asynchronous mapping manner includes the following steps: A1, a reserved value of anyone of the payload structure identifiers is used to indicate the first asynchronous mapping manner; A2, the optical channel transport unit-frame of the first asynchronous mapping manner is constructed, in the adjusting and controlling bytes, at least three bits are used to pre-define the filling state of the positive/negative adjusting bytes, and a negative adjusting byte is added in the overhead zone of the payload unit in the optical channel, a positive adjusting byte is added in the payload structure unit; A3, a reference clock is used in constructing the overclock optical channel transport unit-frame, the frequency is 11.0491Gbit/s±20ppm. Using the above solution, the integrated 10GE LAN signal can be transparent transported in the asynchronous mapping manner through the optical transport network, the frequency deviation of the client signal is well adapted.</p> |
