[STDS-802-3-EPOC] Line coding for EPoC

[Marek Hajduczenia <marek.hajduczenia@xxxxxx>]

Dear colleagues, 

 

I prepared a presentation (as attached) focusing on the topic of line coding
for EPoC, why it is needed and what our options are looking at other
existing Ethernet standards. I also included overview of 64b/66b line code
with some details so that people can start thinking about this topic. My
belief is that we can reuse 64b/66b line coding in EPoC to guarantee good
code-word alignment and have to do absolutely nothing to develop a new line
code for EPoC. The same approach was taken in 10G-EPON and worked just great
? no development errors were committed, and companies could just reuse their
existing implementations from 10GE and other high speed Ethernet PHYs. 

 

The decision on the line code is important, since the selection of the line
code influences other choices, including the FEC code word size, mapping of
individual data vectors into the FEC code word, as well as the following
OFDM symbol size. 

 

I plan to submit this contribution to the upcoming meeting in Orlando and I
would appreciate your feedback and comments ahead of time. 

 

Thank you in advance

regards
