Optical communication technology accelerates , promotes the intelligent development of the industry

In today's digital age, with the steady implementation of the "Digital China" strategy and the in-depth promotion of the "New Infrastructure" strategy, optical fiber communication technology, as a vital supporting force in modern information infrastructure, is rapidly evolving towards intelligence, high bandwidth and low latency at an unprecedented speed.

In the construction journey of "Digital China", various industries are actively undergoing digital transformation, and have put forward higher requirements for the speed, quality and stability of information transmission. The advancement of the "New Infrastructure" strategy has provided a broad stage and strong impetus for the development of optical communication equipment. Under such a background, optical communication technology continues to break through and innovate to meet the growing demand for data transmission.

Especially in key areas such as electricity, transportation, security, and operators, the demand for optical communication products has shown a trend of continuous expansion. In the past, optical communication equipment may mainly meet a single transmission function, but now, market demand has undergone a profound transformation from traditional single transmission to multi-service converged optical terminals.

Among many optical communication solutions, the demand for multi-service optical terminals has grown significantly. In recent years, integrated optical terminals with multiple interfaces such as E1, Ethernet, and serial ports have been favored in the market. The design of this integrated optical terminal has enabled the equipment to show many advantages in practical applications.

From the perspective of room space utilization, traditional optical communication equipment often requires multiple separate devices to meet different business needs, which not only occupies a large amount of room space, but also has complex wiring, increasing the difficulty and cost of operation and maintenance. The integrated optical terminal integrates multiple interfaces and integrates multiple business functions into one device, which greatly saves room space and makes the layout more concise and reasonable.

In terms of wiring, the advantages of multi-service fusion optical terminals are also obvious. Due to its high degree of integration, the connection lines between devices are reduced, thereby simplifying the wiring work. This not only reduces the cost and complexity of wiring, but also improves the stability and reliability of the system. At the same time, for operation and maintenance personnel, equipment maintenance is also more convenient and efficient.

For example, an E1 optical terminal + serial port optical terminal with integrated "4E1 + 4ETH + 32 RS232/485" interface can meet the data and control business synchronization transmission needs of most small and medium-sized sites with its rich interface resources and powerful business processing capabilities. This equipment is widely used in the following scenarios:

（1）In power grid dispatching and telecontrol systems, it transmits voltage, current, power and other information in real time, and controls remote equipment to ensure power grid stability;

（2）In intelligent transportation and highway communications, it transmits sensor data and video signals to assist road monitoring and dispatching.

（3）In front-end video monitoring and control systems, it transmits high-quality images and receives control instructions remotely;

（4）In the integration and transformation of TDM networks/IP networks, it plays a bridging and compatibility role to promote the upgrade of traditional networks to intelligent communications.

（5）In addition to its diverse functions, the reliability of industrial optical transceivers has also become a basic requirement for industry applications. In order to adapt to harsh environments and long-term operation needs, more and more optical communication products have the following characteristics:

        Support wide temperature operation from -40℃ to +75℃, suitable for outdoor substations or high-temperature workshops;

        Provide SNMP remote management function, support network centralized monitoring and equipment alarm.

        Equipped with optical link 1+1 protection switching function, it automatically switches to the backup link when the main link is disconnected to ensure continuous transmission of key data.

While traditional categories such as PDH optical transceivers, Ethernet optical transceivers, and serial optical transceivers continue to evolve, Chinese fiber optic communication manufacturers are also gradually rising in the global market. More and more local companies, relying on stable technical strength and flexible customization capabilities, are exporting their products to Southeast Asia, the Middle East, Latin America, and Eastern Europe, gradually building brand awareness.

Industry insiders pointed out that with the continuous deepening of infrastructure such as 5G communications, industrial Internet, and digital cities, the market demand for cost-effective optical communication solutions will continue to grow, and multi-service optical transceivers and integrated transmission equipment are expected to usher in broader development prospects.

Optical communication is not only a technology, but also a "nervous system" that supports the digital operation of future society. From industrial remote control thousands of miles away to urban monitoring networks in the streets and alleys, fiber optic communication products are driving the world's intelligent process with invisible but solid power.
