Habe a look at G.983.1 "Broadband optical access systems based on Passive Optical Networks (PON)" Its not exactly describing point to point FTTH but for other access protocols. For 1.25GBit/s and single fiber "Diplex" it defines the Downstream optical Window as 1480-1500 - See Page 23. The following pages define a Window of 1260-1360 for the Upstream direction. This matches GPON which uses 1490 for Downstream and 1310 for Upstream. Flo -- Florian Lohoff [email protected]
