Recently, China Telecom issued a notice to open the centralized tender of 2017 PON equipment products. The tender includes GPON equipment, 10G EPON equipment and XG-PON equipment 3 standard packages. The number of GPON devices is estimated to be about 600,000 for the OLT port and about 200,000 for the ONU (including MDU / MTU / SBU). The number of 10G EPON equipment is estimated to be about 450,000 for the OLT port and about 200,000 for the ONU (including MDU / MTU / SBU) wide and narrow port; The number of XG-PON equipment standard package is estimated about 40,000 for OLT port, ONU (including MDU) wide and narrow port about 50,000.
Demand spawned 10G PON
By comparing the tender situation of PON equipment in recent 3 years as the diagram shows, it is found that the purchase volume for GPON equipment has been relatively large, while the purchase volume for EPON equipment has been less and less; there is even no purchase for EPON equipment this year. On the contrary, the purchase volume of 10G EPON equipment has been gradually increased, and there is XG-PON equipment newly-added to purchase this year. From which we can learn the development trend of PON equipment, 10G PON has been gradually the mainstream in telecom market.
The development of 10G PON is referred to the demands of users. With the development of 4K video, virtual reality and other digital services, users have increasing demands for the bandwidth and PON technology could not afford to meet them anymore. To prompt the smooth upgrade of network and speedup of bandwidth, and to accomplish the “100 trillion” to “Gigabit” across based on existing equipment of carriers, upgrading PON technology is the most important key. Under this background, 10G PON comes out and becomes the mainstream technology of access network.
10G PON industry chain has matured
10G PON has advantages in multiple aspects. It is able to upgrade the network on the basis of existing hardware structure, which would largely lower the cost and shorten the refurbishment cycle. More importantly, upgrading PON to 10G PON can enhance bandwidth by 10 times. That is to say, by only upgrading the key components, you can accomplish the stride from the “100 trillion era” into the “gigabit era”.
Not only China Telecom, China Unicom has been also making a positive contribution to the improvement of 10G PON. In 2014, China Unicom conducted 3 times 10G PON research tests in the laboratory, and organized multiple times verifications of new technology in multiple cities over the country. Seen from the purchase of equipment, China Unicom has started to purchase the 10G PON equipment since 2016. Besides, China Unicom network is actively under the large-scale deployment of 10G PON.
At present, some chip suppliers like PMC-Sierra have already been able to provide 10G PON OLT/ONU chips; And 10G PON optical module and equipment are also already available to order in many fiber optic products providers like Cozlink, more than that, some of them have cooperated with multiple carriers over the world for the commercial deployment, which shows 10G PON industry chain has already matured.
100G PON is getting ready for 5G
Gigabit bandwidth is not the extreme, with the rapid development of 8K ultra-high-definition video and Internet of things technology, especially the arrival of 5G era, will bring network greater bandwidth growth demands, in this context, 10G PON will continue developing and evolve to 100G PON.
From the standard progress, 100G PON has been in the IEEE / FSAN / ITU-T and other standardization organizations as the item. IEEE established the NG EPON research group, the standard was named P802.3ca, mainly for 25G PON, 50G PON, 100G PON standardizations, and plans to officially release in May, 2019 the standard; ITU-T also set up a 25G PON research group to research on single wavelength rate enhancement.
For the optical module, Hisense broadband in early 2017 achieved thebreakthrough of 100G EPON optical module technology, increased the optical module rate of the access network to 100G, which means that 10 Gigabit ultra-wideband becomes possible.
In the aspect of optical equipment, currently, Huawei, FiberHome, ZTE has launched 100G PON prototype, can provide users with Gigabit, 10 Gigabit fixed bandwidth access, and also can meet the future demands for mobile broadband access of 5G base station peak rate at least 10Gbit / s, which is leading the future of ultra-bandwidth. Industry experts expected in 2020, 100G PON will “debut” to achieve the scale business.
10G PON equipment and technology is generated to fulfill users’ demands for network bandwidth and performance, in the days of full development of data communication, it is the best solution to higher bandwidth network and communication, and also importantly, it is well prepared for future demands of an upgrade.
