Fiber Optic Access Network Solutions
Fiber to the Home (FTTH): Adopting Passive Optical Network (PON) technologies such as Ethernet Passive Optical Network (EPON) and Gigabit-capable Passive Optical Network (GPON), the optical fiber is directly laid to residential users. At the central office, the Optical Line Terminal (OLT) converts electrical signals into optical signals, which are transmitted through the optical fiber to the Optical Network Unit (ONU) at the user end, and then converted back into electrical signals for use by user devices, providing users with high-speed broadband access services.

Fiber to the Node (FTTN): The optical fiber is laid to nodes close to users, such as distribution boxes in residential areas or junction boxes in corridors, and then the signals are connected to users' homes through other media such as copper cables. This method is suitable for areas where users are concentrated and can reduce construction costs.

Data Center Fiber Optic Solutions
Internal Interconnection: Inside the data center, multimode and single-mode optical fibers are used to connect servers, switches, storage devices, etc. Multimode optical fibers are suitable for short-distance high-speed transmission, such as the connection between racks in the data center; single-mode optical fibers are used for longer-distance connections, such as the connection between different areas within the data center. Optical fiber patch cords, fiber optic distribution frames and other fiber optic products are used to build a high-speed and reliable optical network to meet the data center's requirements for large-capacity and low-latency data transmission.
Interconnection between Data Centers: For the connection between data centers in different geographical locations, single-mode optical cables with a large number of cores, such as 144-core and 288-core cables, are usually used. By using Wavelength Division Multiplexing (WDM) technology, multiple optical signals with different wavelengths can be transmitted in a single optical fiber, greatly increasing the transmission capacity and enabling high-speed data transmission and sharing between data centers.

5G Communication Fiber Optic Solutions
Fronthaul Network: It is used to connect the Radio Remote Unit (RRU) and the Base Band Unit (BBU) of a 5G base station. With its characteristics of high bandwidth, low latency and strong anti-interference ability, optical fiber can meet the requirements of the 5G fronthaul network for high-speed data transmission and ensure high-density communication between base stations.

Backhaul Network: It connects the 5G base station to the core network, usually adopting topological structures such as optical fiber ring networks and tree networks. A large amount of user data and signaling information are transmitted through optical fibers, providing a reliable transmission channel for the stable operation of the 5G network.

Long-distance Trunk Communication Solutions
Single-mode optical fiber is used as the transmission medium. It has extremely low loss near the 1.55μm wavelength and can achieve relay-free transmission for dozens or even hundreds of kilometers. At the same time, Wavelength Division Multiplexing (WDM) technology, including Dense Wavelength Division Multiplexing (DWDM) and Coarse Wavelength Division Multiplexing (CWDM), is applied to transmit multiple optical signals with different wavelengths in a single optical fiber, increasing the transmission capacity of the long-distance trunk. In addition, optical amplifiers and other devices are used to amplify and relay the optical signals to compensate for the attenuation of the signals during the transmission process and ensure the signal quality for long-distance transmission.

Optical Transceiver Communication Solutions
In fields such as industrial automation and remote monitoring, optical transceivers are used to convert various signals, such as switch signals, analog signals, and digital signals, into optical signals for transmission through optical fibers. Optical transceivers include digital optical transceivers, analog optical transceivers and multi-service optical transceivers, etc., and appropriate optical transceivers can be selected according to different application requirements. Digital optical transceivers are suitable for scenarios with high requirements for signal transmission quality; analog optical transceivers can maintain the continuity of signals and are suitable for certain specific industrial applications; multi-service optical transceivers can integrate multiple communication services to meet diverse communication needs.
