said by sonicmerlin:XGPON equipment (in the form of 10GPON1 that is practically 8 Gbps down, 2 Gbps up and compatible with existing GPON) may be commercially available as early as sometime next year. Don't know what Verizon's plans are but what is really cool is that 10GPON1 (uses it own two compatible wavelengths) and GPON will be able to be offered in the same neighborhood at the same time.
Cable DOCSIS 3 shares 100-200 mbits between hundreds of customers. BPON shares 640 mbits between at most 32 customers. GPON ups that to 2.4 gbits between 32, and is now the standard. XGPON ups that to 10 gbits and will be the standard in a few years.
