GPON is a passive optical network (PON) that delivers high-speed broadband access by using a single optical fiber to connect multiple users to a service provider’s central office. GPON technology is widely used for FTTH (fiber-to-the-home) applications, providing high-speed internet, television, and telephone services.
GPON uses a point-to-multipoint architecture, where a single optical line terminal (OLT) at the central office connects to multiple optical network units (ONUs) at the user’s premises. The OLT converts electrical signals into optical signals and transmits them over the fiber, while the ONU converts the optical signals back into electrical signals for the user’s devices.
GPON technology is known for its high bandwidth, long reach, and low cost. It can support up to 2.5 Gbps downstream and 1.25 Gbps upstream, with a reach of up to 60 km. GPON is also highly scalable, allowing service providers to easily add or remove users as needed.
GPON technology is widely used by service providers around the world, including Verizon, AT&T, and China Telecom. It is also used in many FTTH deployments, such as Google Fiber and CenturyLink.
XG-PON (10-Gigabit-capable Passive Optical Network) is a next-generation passive optical network (PON) technology that provides high-speed broadband access. It is a point-to-multipoint architecture that uses a single optical fiber to connect multiple users to a service provider’s central office. XG-PON technology is an evolution of GPON (Gigabit-capable Passive Optical Network) and provides ten times the bandwidth of GPON.
XG-PON uses a wavelength division multiplexing (WDM) technique to transmit multiple signals over a single optical fiber. It operates on two wavelengths: one for downstream (from the central office to the user) and one for upstream (from the user to the central office). The downstream wavelength operates at 1577 nm and provides a maximum bandwidth of 10 Gbps, while the upstream wavelength operates at 1270 nm and provides a maximum bandwidth of 2.5 Gbps.
XG-PON technology is highly scalable, allowing service providers to easily add or remove users as needed. It can support up to 128 users per optical line terminal (OLT) and has a reach of up to 60 km. XG-PON is also highly reliable, with a bit error rate of less than 10^-12.
XG-PON technology is used by service providers around the world, including Verizon, AT&T, and China Telecom. It is also used in many FTTH (fiber-to-the-home) deployments, such as Google Fiber and CenturyLink. XG-PON is a cost-effective solution for providing high-speed broadband access to residential and business customers.
