A Passive Optical Network (PON) is a point-to-multipoint, fiber to the premises network architecture in which passive optical splitters are used to enable a single optical fiber to serve several functions. There has always been a development in telecommunication sector. As can be seen by the progress of standards from APON to BPON to GPON, and from EPON to GEPON, the industry is looking at ways to deliver even more bandwidth over longer distances than ever before. Two ways of doing this are by increasing the number of optical wavelengths being used on the PON fiber, and by increasing the bandwidth and bandwidth efficiency of each wavelength.
