First, thanks for the replies.
[4] Some recent threads on NANOG discussed physical layer issues like
SONET, SDH, circuit layout etc. Could somebody point me to
technical papers / articles / books which describe fiber and
copper technology in detail.
Ask in comp.dcom.telecom.tech.
Judging from the answers to this question, I gather I didn't phrase
the question correctly. What I am looking for some is practical
literature on fiber and copper technology - stuff which network
operators and designers need and use. I would have guessed there
would be an equivalent to say what the Stevens Books are to TCP/IP.
Or have most people on this list learnt their skill by experience
only?

No problem. Although apparently I was wrong on point 3.

Sorry, misunderstood.
Hmmmm... Layer 1? Physical? Not sure. The layer 2 stuff is covered
to some detail in _Digital_Telephony_, which alas, I can't give a cite
for right now, as it's at home. Mail me privately, and I'll be glad
to.
Also, the readers of that NG are likely to have other references to
hand; many work for IXC's, LEC's and switch mfr's.
Cheers,
