What is the relationship between GPON and FTTx networks?

Furukawa Electric offers insights into why passive networks represent the future of connectivity and how they are related to FTTx networks.

Developing an awareness of passive optical networks (GPONs) is the first step towards understanding how this solution applies to the various types of fiber-optic connections. This type of application offers a series of advantages for both implementing organizations and clients.

The main characteristics of GPONs are its capacity for traffic of up to 2.5 Gbps downstream and 1.25 Gbps upstream. GPONs provide networks with stability and offer scalability in broadband connections. Additionally, the efficiency rate seen in GPONs can reach up 92%. These characteristics, among others, means that GPONs offer capacity, range and reduce the volume of fibers used. As a result, infrastructure managers can monitor data more easily, thereby reducing costs associated with maintenance and electricity.

So, how exactly are GPONs related to FTTx networks? FTTx is a term used to designate passive optical networks that connect a central point at the access provider to a wide range of users. These connections can be:
● Residential (FTTH, Fiber to The Home)
● Building (MDU, Multi Dwelling Units)
● Corporate (FTTB, Fiber to The Building)

Point-to-multipoint topology allows a single fiber to serve several different clients thanks to passive fiber splitters that are used to distribute bandwidth. FTTx provides a scalable model that allows for future network expansions without compromising signal quality.

The use of GPON technology has expanded exponentially and its popularity is expected to continue to grow over the coming years. GPON is ideal for use in modern FTTH connections, which continue to gain leverage in both large urban centers and more remote areas. It is important to recognize that, when designing and building an FTTx network, long-term strategic thinking is essential to business success.
