Dear HSSG Members,
I am going to apologize up front for missing some of the content of the meeting in my notes. I did not
take shorthand in school and this has left me somewhat unprepared for the job! :)
If anyone notices an error or omission, please contact me directly and I will update these notes and when
they are final, have them posted on the HSSG-FOAH website.
Regards,
Dan Dove

Notes:
Pete's
Presentation
================
Petar P: Should we consider other
effects like polarization, etc?
Pete A: There are some well known
differences between fiber... to include real data into the spreadsheet is tricky
because you suffer from the problem that information is sometimes too
optimistic
Petar P: In some countries where
legacy is prevalent, we might need more data to support those
fibers
Pete A: Even DPQSK or 25G/lane over
40Km would likely be able to operate over such fibers
Frank: We need guidelines for all
parameters
Dan: Are there any other parameters
that we should be including in the spreadsheet?
Pete A: Not in a position to put
down something that is useful. Some info available, for example at recent
OFC, some operators were presenting
PMD distribution information.
Chris: Don't see us spending time on
that. Loss & Dispersion are key parameters. Dave Cunningham made a
presentation in
Piers: Easy question, is skew delay
the integral of chromatic dispersion?
Pete: Y.
Piers: Concerned about the method
applied to derive data, that it is different than conventional (Piers correct me
if I misstated this)
Piers: 10G EPON people re-arranging
the look/feel of the spreadsheet. Would we want to accept this as the basis for
forward movement, then align with the 10G EPON activity as they
proceed?
Pete A: 10G EPON is addressing
different problems.
John Jaeger: <I totally missed John’s point and was unable to
transcript>
Chris C: update to models going to
be much bigger task.
Conversation got too
fast for chair to record. Feel free to insert if you have
it.
Straw Poll: Adopt
spreadsheet "FOAH_anslow_02_0407.xls" as the basis for future work
and presentations in the
HSSG with regard to attenuation, dispersion & skew for
single mode fiber cables
including splices.
No
Objection:
Chris Cole's
Presentation
====================
Added Optical Amplification and
Dispersion Compensation terms into spreadsheet.
Mike D: Should we add "cooled" as a
term?
Chris C: Believes this term is very
implementation dependent in most cases, and thus difficult to capture. Agrees it
is an important parameter. Maybe belongs on 2nd sheet.
Mike D: OA and DC are costs as well
vs technical feasibility.
Chris: Yes, ultimately all things
translate to cost.
Dan D: What about adding cooling
only to mandatory boxes?
Chris C: 10x10DML1310 10/140 &
all four 2x50G boxes would be included other candidates? 40K DML 5x20 or 4x25
maybe
Chris C: Will make the changes and
send out
Chris C: Any concerns with boxes
labeled OA or DC? Should we add/subtract?
Pete A :Why is ML not EML in the
table now?
Chris C: Possible that modulator
structure might be different than assumed.
Pete A: Would we not also add 10x10
ML?
Chris C: yes
Chris C: Which boxes are you looking
at? We are looking at 5x20 and 4x25 1310 DML and ML
John D: When TF is formed, people
will begin to compare alternatives
Chris C: Will send out on reflector
to request input on what people are investigating
Chris C: Moving on, Slide 4 listed alternatives Pete, did I
get this right?
Pete: No. No end points
defined.
Chris C: CWDM expected 40% cost
savings for uncooled approaches, 4-5 channel pretty
feasible
Chris C: Speaking to slide 6,
adopting an optimum grid is going to be very important if WDM
used.
Pete A: Comment on "strongly
resonate with * note, not with proposal to rename to IWDM.
Chris C: Looking for input from
other members of FOAH to provide optimum grid.
Pete A: Brief mention of 40G, any
need for input from FOAH on that topic? I believe there is a need for this. If
10x10, pretty straight forward how you might proceed... 4x10. However, if we
went 5x20 or 4x25, it might change how you would proceed.
Chris C: Strictly data center, not
any indication of 10Km or 40Km reach requirements.
Piers: What if 40G were 5x and 100G
were 20x?
John: Requests for presentation time
are due by April
