This ability can be doubled to supply 80 Gbps downstream and 20 Gbps upstream in case study solution extended NG PON2. Symmetrical Upstream and Downstream CapacityBoth case study solution basic and extended implementations are designed to entice domestic buyers where gigabit downstream speeds may be needed but more modest upstream needs be triumphant. For business users with data mirroring and similar requirements, a symmetric implementation might be offered giving 40/40 and 80/80 Gbps capacity respectively. With case study solution advent of NG PON2, there is now an obvious change among optical access network and copper access community capabilities. Investment in NG PON2 provides a far inexpensive network to perform, considerably faster downstream and upstream speeds and a future proof upgrade path all of which copper access networks do not deliver, thus making them out of date applied sciences. Telephone groups around case study answer world were carrying out trials of NG PON2 and key telecommunication proprietors have rushed NG PON2 items to market.
