Dear colleagues,

Here is the revised text of the Distinct Identity and Compatibility Critters as discussed and revised today at the meeting. I also attach updated project objectives per discussion at the meeting today – I extracted these from ExEPON_1111_hajduczenia_1 we examined at the meeting.

Regards

Marek

Subject: [802.3_EXTND_EPON] Objectives under discussion

Objectives we discussed in the morning

» Support subscriber access networks using point-to-multipoint topologies on SM optical fiber

» EPON PHY(s) to have a BER better than or equal to 10^-12 at the MAC/PLS service interface

» Provide physical layer specifications:

˃ for 1G-EPON supporting a downstream channel insertion loss of 29dB, compatible with PRX30 upstream;

˃ for 1G-EPON supporting a channel insertion loss of at least 32 dB, with the split of at least 1:64 at the distance of at least 20 km;

˃ for 10G-EPON, supporting a channel insertion loss of at least 32 dB, with the split of at least 1:64 at the distance of at least 20 km;

» Changes to be confined to the PMD layer; PCS and MPCP are to be reused as is.

» Maintain coexistence among 1G-EPON and 10G-EPON (i.e. support the same loss budget classes for 1G-EPON and 10G-EPON).
