Gigabit Passive Optical Network (GPON) technology is a type of passive optical network (PON) that delivers high-speed broadband services to homes and businesses. It is widely adopted for its efficiency, scalability, and ability to provide gigabit-level internet speeds. This article explores the key features, benefits, challenges, and applications of GPON, highlighting its significance in modern telecommunications.
Understanding GPON
What Is GPON?
GPON is a point-to-multipoint access mechanism that uses optical fiber to deliver broadband network access from a single optical line terminal (OLT) to multiple optical network units (ONUs) or optical network terminals (ONTs). It operates by splitting the optical signal using passive splitters, allowing a single fiber to serve multiple endpoints, making it a cost-effective solution for delivering high-speed internet.
