He aha nā mea e hoʻololi ʻia ai ka ʻoihana Fiber Optic Access Network i ka 5G Era?
Ua ʻike mākou i ka piʻi ʻana o ka bandwidth 5G, hoʻohemo i ka hoʻohaʻahaʻa a me ke kākoʻo ikaika ʻana i ka Pūnaewele o Mea. Kono ia i kahi hoʻohālike nui i ka ʻoihana ʻike hoʻokani kūhelu kumu. ʻO ka mea mua, no nā lawelawe pūnaewele kuʻuna, ua hoʻonui ʻia ka bandwidth o nā mea hoʻohana i ka 1 ~ 10Gbps. Hoʻemi ʻia ka neʻe i ka 1 ~ 10ms, kahi kaulike me ka hana hoʻokipa hoʻokipa paʻa paʻa. ʻO ka bandwidth a me ka lohi i ka pono o ke komo ʻana o ka ʻike kūlohelohe i nalowale i ke alo o 5G, a me ka hōʻoluʻolu o ka neʻe ka mea e hoʻonui i ka neʻe i nā ʻoihana hou aku i ka ʻoihana kelepona 5G. ʻO ka lua, No ka ʻoihana IoT, loaʻa ka 5G IoT i kahi ākea ākea, nā lawelawe lawelawe pono, nā pilina hoʻokipa maʻamau, maʻalahi ka hana maʻalahi a me ka mālama ʻana, a me nā kumukūʻai haʻahaʻa ma mua o ka puka o IoT.

ʻO nā luʻi a me nā manawa kūpono no nā ʻoihana loiloi optical i ka  5G ʻO  era
As the most important information and communication infrastructure for the digital transformation of the whole society, 5G will realize the interconnection of all things, and connect people and machines, environment, etc. more closely and efficiently, and it is convenient, fast, intelligent and reliable. The communication connection will lead to innovation and evolution of the whole society’s production mode, business model and lifestyle.
Compared with 4G, 5G can provide stronger services, subdivided into three telecom business scenarios, one is enhanced mobile broadband (eMBB) with a peak rate of up to 10Gbps, and the other is that the number of connections can reach 1 million per square kilometer. Connected to the Internet of Things (mMTC), the third is low-latency, high-reliability communication (URLLC) with an end-to-end delay of 1ms, such as the Internet of Vehicles.
We have seen 5G’s bandwidth increase, delay reduction and stronger support for the Internet of Things. It also poses a huge challenge to the traditional optical access network. First, for traditional Internet services, the bandwidth of mobile users is increased to 1~10Gbps. The delay is reduced to 1~10ms, which is basically equivalent to the fixed-line optical access performance. The bandwidth and delay advantage of traditional optical access is lost in the face of 5G, and the convenience of mobility will increase the transfer of more traffic to the 5G wireless network. Secondly, For the IoT service, the 5G IoT has a wide coverage, convenient service delivery, standardized interfaces, easier operation and maintenance, and lower costs than the IoT gateway.
On the other hand, the development of 5G brings new opportunities to optical access networks. First, 5G using AAU and DU separation architecture, and because of such high frequency introducing 5G AAU huge number, a 4G times 2 or more times, so 5G before the transmission network becomes very important, the key to the optical fiber resources become deployed; this has been built a high-density coverage ODN network, low cost and easy access on demand. 5G AAUs, WDM-PON technologies provide a wide range of applications. Secondly, 5G uses high-frequency signals, which has the weak wall-to-wall capability, and there is also a problem of bandwidth degradation and unstable access quality at the edge of the wireless network. In contrast, the bandwidth and quality of service of optical access fixed-line users are independent of distance. Is a huge advantage.
Operators can consider the advantages of integrated 5G wireless access and optical access to form a supplement. They rely on the large ODN fiber resources and stable large-bandwidth access that has been built on the existing network to provide users with stable and reliable 5G+FTTH dual-gigabit access.
