279:(OLT), is housed within the central office of the telecommunications operator. A laser in the OLT injects photons from the central office into a glass-and-plastic fiber-optic cable that terminates at a passive optical splitter. The splitter divides the single signal from the central office into many signals that can be sent to up to 64 consumers. The number of consumers serviced by a single laser is determined by the operator's engineering criteria; operators may opt to reduce the number to 32 consumers. Furthermore, the operator may choose to divide the signal twice, for example, once into eight and again farther down the line. The maximum distance between the central office and the site can be 20 kilometers, however operators will normally limit it to 16 kilometers in order to maintain a high level of service. 43: 152: 232:
GPON puts requirements on the optical medium and the hardware used to access it, and defines the manner in which Ethernet frames are converted to an optical signal, as well as the parameters of that signal. The bandwidth of the single connection between the OLT

The first version of GPON was ratified in 2003. Since then, it has been expanded upon and revised several times. Work on the standard continues. As of July 2018, G.984.5 is currently being revised. The most recent version comprises seven parts:
