What is XGS-PON?

XGS-PON (10 Gigabit Symmetrical Passive Optical Network) is a point to multi-point fiber-based access network technology with passive optical components that can deliver last-mile broadband network access at speeds of up to 10 Gbps downstream and 10 Gbps upstream, XGS-PON is defined by the ITU-T G.9807 family of specifications.

Gigabit Passive Optical Network (GPON) standard is the primary fiber-based transmission technology widely deployed today that is delivering last-mile broadband network access. However, GPON is only capable of supplying this network access at speeds of up to 2.4 Gbps downstream and 1.2 Gbps upstream which is not sufficient for supporting the higher bandwidth consuming applications in homes and businesses. Hence, XGS-PON enables internet service providers to offer superior high-speed internet, video, and voice services to consumers and businesses.

In turn, these customers benefit from XGS-PON’s significant step-up in bandwidth by experiencing better performance when gaming (particularly cloud-based), using multiple streaming devices simultaneously, and consuming higher resolution content (e.g., 4K and 8K video). XGS-PON technology can serve up to 256 customers on a single fiber. In contrast, GPON can support only 64 customers and typically these networks do not serve more than 32 customers.

XGS-GPON uses a single strand fiber network that reaches from the access concentrator at a service provider site to each subscriber side demarcation device.

XGS-GPON uses a single strand fiber network that reaches from the access concentrator at a service provider site (an Optical Line Terminal or “OLT”) to each subscriber side demarcation device (called an Optical Network Terminal or “ONT”).
