Re: [8023-10GEPON] [FEC] upstream lock status - Hamming distance of 31
Dear Pedro,
Thank you for the valuable input. I would like to add that in the below set
of 49 delimiters, delimiter #42 has maximum run length of 4 and 32/34
balance.
"110100011000011110111000101100110111010110101001000010011001011011"
Delimiters 13 and 14 have running lengths of 5, but perfect balance 33/33.
"010100100100001111101000110100101011000100011001100010110111110111"
"010100011010111000001100111010010101101111001111100001111100001000"
I think either of those would be a fine candidate for burst delimiter.
