Re: [8023-10GEPON] [POWER_BUDGET] ad hoc group 2nd meeting
Dear Tatsuta-san,
Would You be able to estimate what channel insertion loss would be observed in this type of a system should 1x64 split PON be constructed with 10km reach ?
Best wishes

Dear Frank,
This is Tsutomu TATSUTA from NTT.

Unfortunately, we use more connectors in a real field than you image.
So, we need 29dB only if we use 32 split ratio.
Sincerely yours,
