Broadband access Gigabit access era, 10G PON PON has become the mainstream technology, the traditional PON is to 10G PON upgrade, broadband will increase 10 times. 10G PON scale commercial launch, will directly help FTTH to Gigabit access rate evolution. The company is located in: 10G PON has many advantages, based on the existing hardware architecture to upgrade the network, greatly reducing costs, and shorten the transformation cycle, more crucially, PON upgrade to 10G PON, the bandwidth can be increased 10 times. Only through the upgrading of key components, you can enter the “Gigabit era” from the “Fast trillion times.” Gigabit bandwidth is not the limit, with the rapid development of 8K ultra-high definition video and Internet of Things technology, especially the advent of the 5G era, will bring greater bandwidth demand for the network growth, in this context, 10G PON will continue Development, will be 100G PON evolution. From the standard progress, 100G PON has been in IEEE / FSAN / ITU-T and other standardization organizations. IEEE set up the NG EPON research group, the standard named P802.3ca, mainly for 25G PON, 50G PON, 100G PON standardization is scheduled to be released in May 2019 standards; ITU-T also set up a 25G PON research group, Research on single wavelength rate improvement.
