The main Fibre To The Home (FTTH) technology we have deployed is Gigabit Passive Optical Network (GPON).
hg0088管理this shares a system capacity of 2.5 gbps downstream and 1.25 gbps upstream across typically 32 to 64 customers. this enables our customers to reach the peak speeds of 1 gbps outlined in our gigabit society vision.
hg0088管理we can evolve these ftth networks by overlaying additional optical wavelengths of new pon technologies such as xgs-pon (10 gbit/s symmetric) and ng-pon2 (40 gbps via four additional wavelengths). hence, the asset life of our fibre investment should be good for a few decades. we can use it for consumers, business customers and mobile infrastructure such as small cell backhaul.
we have also started to evolve our cable networks to docsis 3.1, which will allow them to deliver speeds of up to 1 gbps to customers.
