2024 Prospects for Optical Communication Development
From LPO to silicon light, from coherent sinking to coherent upper limit, from FTTR to 5G, how does optical communication develop in 2024?
More professional, More timely, More reliable, More profitable!
From LPO to silicon light, from coherent sinking to coherent upper limit, from FTTR to 5G, how does optical communication develop in 2024?
Plastic optical fibers are particularly suitable for FTTH due to the characteristics of thick core diameter, easy coupling, no need for fusion or welding, light weight, good flexibility and bendability. At the same time, they have anti-corrosion, moisture-proof, shockproof and explosion-proof functions, and are resistant to electromagnetic interference and radiation. They have strong confidentiality, safety, and anti-interference capabilities, decay to a constant value, and do not change with transmission status.
China 5G package users have reached 1.3 billion, and ARPU has also increased by 0.4% from 48 yuan. However, 5G has not seen the rapid growth in user traffic seen in the 4G era.
5G base station is the core equipment of 5G network, providing wireless coverage and realizing wireless signal transmission between wired communication network and wireless terminals. The architecture and form of the base station directly affect how the 5G network is deployed. Since the higher the frequency, the greater the attenuation during signal propagation, the density of base stations in the 5G network will be higher.
The power consumption of a 5G single station is 2.5 to 3.5 times that of a 4G single station. The increase in AAU power consumption is the main reason. And the current full load power of a single station is nearly 3700W, and the existing network power supply and supporting facilities need to be expanded in advance.
the single wave capacity of 400G for short distance transmission has gradually matured, and it is expected to achieve large-scale commercial long-distance transmission by 2024.
Both GPON and EPON belong to passive optical networks and are widely used in FTTH. Nowadays, most households are connected to EPON and GPON, achieving the integration of telephone, broadband internet, and IPTV networks. A single fiber optic cable is used to solve the problem of making phone calls, accessing the internet, and watching TV. In the early days, there were many EPONs, but now they are mostly GPONs.
The internet slow may be happen with many reasons: Wifi capacity, frequency band, network patch cord, and modem, application size, router speed, etc.
Fiber-to-the-home and optical-to-copper transitions require the transformation of household lines, ftth requires power supply support, resulting in power consumption, and depend on electricity, if no power, no signal.
FTTH is fiber to the home, “Fiber To The Home” means that the line connected to your home is optical fiber instead of ordinary network cable.
Except old wavebands in fiber optic communication, optical networks have emerged in the CE, Cpp, and C+L bands, this article will explain all of them and their applications.
January 23, 2024 Huawei Technologies Co., Ltd. recently disclosed an FTTR patent, public number: CN117426105A. The application date for this patent is May 17, 2021.
