All, This is just a quick note to alert everybody to our work
item on dual rate 1G-10G PMD for EPON. The group will use the exploder for all correspondence, but
we will try to include the tag [Dual-Rate-PMD] on all Emails. If you couldn’t care less about the topic, you can set
your Email filters appropriately. To the matter at hand, I think the first order of business
is to prepare a short tutorial slide-set that covers the key issues of PMD
design and link rate. Those considerations are at the base of the problem that we
face. Stay tuned for more details. On a side issue, we also had a question on the issue of
modifying the line rate to accommodate FEC. The tutorial mentioned above
will also inform that debate, in that it will quantify the PMD sensitivity
penalty that comes from link rate increase. A bonus, free of
charge. J Sincerely, Dr. Frank J. Effenberger Huawei Technologies Office (732) 625 3002 Cell (908) 670 3889 |
