GPON: Optimal Solution to FTTH
Recently, the increasing spread of the Internet is the major driver for the development of new
access technologies, which demand more capacities carry to bandwidth. Among these
technologies, Fiber to the Home (FTTH) appears the most suitable choice. An optimal option for
FTTH technology, Gigabit Passive Optical Network (GPON) provides one of the most cost‐effective
ways to bandwidth‐intensive applications and establishes a long‐term strategic position in the
broadband market.
GPON Applies in FTTH
Gigabit Passive Optical Network (GPON) provides the reliability and performance expected for
business services and an attractive way to deliver residential services. GPON enables Fiber to the
Home (FTTH) deployments economically resulting to accelerate growth worldwide. The following
picture shows how the GPON OLT device deployed in a typical GPON network delivers services to
residential homes. Signals from the central office OLT transmits to the splitter, then the splitter
spreads the signal to the GPON ONT, the GPON ONT connects residential homes.

Features of the GPON Networks
Provide downstream speeds of 2.5 Gbps and upstream speeds of 1.25 Gbps.
Support long distances of up to 20 km and unlike copper does not suffer from decreasing
performance over distance.
Standards based and equipment are available from a large and growing number of vendors
giving service providers the peace of mind with being locked into a single vendor.
Inherently secure wherein wiretapping, eavesdropping and other hacking is nearly impossible.
Advantages of GPON Networks
The most obvious advantage of PON networks is that a single shared optical fiber can support
multiple users through the use of inexpensive passive optical splitters. In GPON networks, up to 64
ONTs can share one fiber connection to the OLT. This makes GPON an attractive option for service
providers wanting to replace copper networks with fiber, particularly in high‐density urban areas.
Allow service providers to deliver more capacity to carry bandwidth‐intensive applications.
Provide one of the most cost‐effective ways for a service providers to deploy fiber.
Provide a future proof mode of access as the speed of the broadband connection is limited by
the terminal equipment rather than the fiber itself. Future speed improvements can be
achieved via equipment upgrades before any upgrades on the fiber itself.
Demands for access networks have promoted deployment of FTTH technologies. As an optimal
solution to these technologies, GPON provides the unique features and advantages applied in

FTTH. To meet the demand of GPON in access networks worldwide, Sun Telecom has developed
FTTx solutions.
