FAS is the frame alignment overhead, the length is 6 bytes, and it is located in the 1st to 6th columns of the first row. The 1st to 3rd bytes are 3 OA1 bytes, and each OA1 is always "1111 0110", that is, 16 F6 in hexadecimal; the 4th to 6th bytes are 3 OA2 bytes, and each OA2 is always "0010 1000", that is, 28 in hexadecimal.
