As we all know, building an all Fibre-to-the-home network gives you a reliable network that will serve for years to come, but it takes a long time and significant investment to execute. In many cases an operator needs to deal with a wide variety of geographical situations and customer concerns which pose difficulties bringing the fibre into the house. However, as broadband is becoming a utility, a service that is expected to be available with decent quality at all times, end-users expect operators to continually improve the network and provide higher speed broadband services. Therefore, operators around the world are bringing fibre deeper into the network and bridging that gap with the technology that makes most business sense.

In situations where there is high quality copper available or where it is difficult to get local power, operators can also opt for a fibre-to-the-distribution point approach (FTTdp).

FTTdp uses a Distribution Point Unit (DPU) and Network Connection Device (NCD) to deliver fibre-like broadband services. The DPU is installed as close to the end-user as possible while the NCD goes into the home. Given the differences in geographical environment and the difference in how close an operator can bring the fibre, there are different requirements on the DPU: different number of ports, VDSL or G.fast depending on the copper loop lengths, form factor and shape. Although the technology inside is always the same, every network is different and requires small modifications.
