A Gigbit Passive Optical Network (GPON) is a cutting edge cabling and technology solution to support telephone, data, wireless, security cameras and access control at terabit bandwidth and gigabit speed over fiber optics. Utilizing a fiber optics, we are able to decrease the amount of cabling and hardware required to bring a host of critical services to all points of a facility, often at great distances. Installation time and physical space required are measurably reduced compared to legacy cabling methods.
GPON is comprised of two main active (powered) components—an optical line terminal (OLT), typically located in the Server Room/ equipment room, and optical network terminals (ONTs) that provide service to the end users. A network of singlemode fiber (SMF) and passive (non-powered) optical splitters connects the OLT to the ONUs. The fiber and passive equipment between the OLT and ONTs are often simply referred to as the optical distribution network (ODN).
The OLT provides the interface between the network’s core switch and the ONTs. The OLT encodes Ethernet data for transmission to the ONTs and manages the upstream data traffic from the ONTs to the OLT through the ODN. The ONTs then distribute the signal wirelessly or via twisted pair data cable to a variety of Internet Protocol (IP)-enabled devices, such as computers, wireless access points (WAPs) and Voice-over-IP (VoIP) phones.
