Hi Tom,

Sorry for this late reply to your comment. As this was very initial draft, we did not have time to fix issues raised by you. We will address your comment in the next revision. 

Thanks.
Young

I wonder who the target audience is for this I-D.  The absence of Normative References might suggest that everyone will be able to understand it; or perhaps not:-)

I note the impressive list of editors for the I-D; I wonder if they can be put to work coming up with YANG reference clauses for the objects defined herein e.g. Reed-Solomon and Hamming are fine for me but I need some pointers for Golay or the for the difference between  identity DP_QAM8 {description
      "DP-QAM8 (Dual Polarization Quadrature Amplitude Modulation)";  and  identity DC_DP_QAM8 {description
      "DC DP-QAM8 (Dual Polarization Quadrature Amplitude Modulation)"; different identities, same description.

I believe in a reference for every leaf, every identity, every typedef unless there is clearly no need thereof.  And I think that the G.65x, G.69x that you do mention will be Normative References, which, in turn, gives a pointer to who is expected to be able to understand this I-D.
And I believe in having references ab initio, to clarify understanding, not something to be added just prior to requesting publication.

And I note
'   that may be used in the interfaces colored in yellow in Figure 1.'

Mmm, I wonder how the RFC Editor will specify yellow lines.

So, I am left wondering does it belong in the IETF or is there a better home for it, one, e.g., which can print its standards in colour (sorry, color)?

There are some lines too long and some quirky spellings, but they can wait.
