● Fiber optic transmission medium:

Fiber optic is the main transmission medium of optical access network. It has many excellent properties, such as low loss, high bandwidth, anti-interference, etc. It can achieve long-distance transmission and high-speed transmission through fiber optic.

● Optical module and optical fiber:

The optical access network uses optical module to convert electrical signals into optical signals, which are transmitted to the user end through optical fiber. The selection and deployment of optical module and optical fiber have an important impact on the network transmission speed and transmission quality.

● Optical signal transmission:

The optical signal is transmitted to the user end through optical fiber, converted into electrical signals by ONT, and then transmitted to the user's equipment, such as computers, routers and other devices. The data sent by the user equipment is also converted into optical signals by ONT, and then transmitted to OLT through optical fiber. Through the conversion of electrical signals and optical signals, it is finally connected to the Internet.

● Fiber optic network management:

After the optical access network is successfully connected, network management and monitoring are required, which includes equipment management, bandwidth management, security management and other projects. Through the network management system, operators can realize remote monitoring, troubleshooting, resource allocation and other functions of the network.

● High-speed transmission:

The optical access network transmission speed supports up to hundreds of megabits or even gigabits, meeting your needs for high-speed data transmission, providing faster web page loading speed, smooth video playback experience, while speeding up file upload and download speeds, improving work efficiency and user experience.

Currently, there are GPON, XGPON, XGSPON and even 50G PON high-speed networks.

● Stable and reliable:

Fiber optic transmission will not be affected by interference and electromagnetic interference, reducing the risk of network interruption and data loss, and has a long transmission distance, and will not cause speed reduction or signal quality reduction due to long distance, ensuring the stability of network connection.

● Security guarantee:

The optical access network adopts fiber optic transmission technology. Through encryption technology and security protection mechanism, eavesdropping or interference can be prevented during data transmission, effectively protecting data security, avoiding the risk of data leakage and information theft, and having high security.

● Environmental protection and energy saving:

Fiber optic transmission has excellent environmental protection performance, with the characteristics of low energy consumption and low electromagnetic radiation, which is conducive to environmental protection and energy saving, reducing the impact on the environment, and more in line with the concept of sustainable development.

● High scalability:

The optical splitter can easily achieve user-side expansion without large-scale changes to the existing network infrastructure, with flexible deployment and strong scalability.

● Support for multi-service integration:

The optical access network can simultaneously transmit multiple services, such as broadband data, voice, video, IPTV and 5G backhaul, to meet the needs of different types of users.

● Easy to maintain:

Compared with copper cables, optical fibers have a longer service life and do not need to be replaced frequently. At the same time, the passive components of the optical access network reduce the complexity of the network and reduce maintenance costs.

Typical applications

The optical access network has been widely used in home broadband (FTTH), enterprise dedicated line access, video surveillance, smart cities and 5G networks, and is an important pillar technology for modern communication networks.
