[802.3ae_Serial] Updated issue list; phone conference tomorrow as usual
Here are the list of actions from the database with some other known to-do
items. You will see that the comment database is pretty repetitive:
basically, check all the dB numbers in all the tables. By eliminating
unallocated margin and making the link attenuation normative, we should end
up with simpler, more understandable tables. I am working on a spreadsheet
update to support this.
Serial PMD ad hoc issues list
-----------------------------
# numbers are from comment database
General
-------
Liaison letter from ITU-T SG15
Optical power measurement in network maintenance
(Technical feasibility - covered by other groups)
All wavelengths
---------------
# 317 combine Rx jitter tolerance and Rx sensitivity tests
further work (add calibration sequence, etc.).
Road-test jitter and stressed sensitivity measurements
Jitter spec values
Road-test the test patterns (LAN and WAN?)
SR/SW
-----
# 77
Check SR/ SW Rx sensitivity value. May need to allow for jitter penalty.
# 78
Check SR/ SW stressed Rx sensitivity value. May need to allow for jitter
penalty.
# 79
Check SR/ SW vertical eye closure penalty value.
# 81
Check SR/ SW link power penalties.
LR/LW
-----
Obtaining test fibers or equivalent for 1310 dispersion penalty measurement
# 364
power budget, 1310 nm Tables 52- 12, table 52- 14 and tables 52- 15 are not
clear understandable and probably inconsistent.
Send to Serial PMD ad hoc.
# 367,368,130
maximum average transmitter power and receiver overload changed to 0.5 dBm
by #130 and sent to Serial PMD ad hoc for final resolution.
# 89
Check LR/ LW Tx triple trade off table.
# 86
Check LR/ LW Rx sensitivity value. May need to allow for jitter penalty.
# 87
Check LR/ LW stressed Rx sensitivity value: thought very demanding by some.
May need to
allow for jitter penalty.
# 88
Check LR/ LW vertical eye closure penalty value.
# 90
Check LR/ LW link power penalties. Need to allow for reflection noise and,
to be decided,
jitter penalty.
ER/EW
-----
# 363
power budget, 1550 nm Tables 52- 17, table 52- 18 and tables 52- 19 are not
clear understandable and probably inconsistent.
Send to Serial PMD ad hoc.
# 96
Check ER/ EW link power penalties. May need to allow for jitter penalty, to
be decided.
