High-Performance Voice over Fiber Multiplexer for FXS/FXO and Gigabit Ethernet

In today's era of rapid development of information technology, modern communication network architecture is undergoing a profound transformation, and is increasingly showing a clear trend of convergence and fiberization. Against this backdrop, how to efficiently and securely achieve unified transmission of voice and data services has become a core issue of concern to many key areas such as telecom operators, government and enterprise private networks, transportation hubs, energy systems, and emergency command. Especially in the process of migrating from TDM to all-optical networks, there is an urgent need for a type of highly reliable voice optical transceiver that can achieve the convergence of voice and data without changing the existing voice architecture.

For telecom operators, with the continuous expansion of business and the sharp increase in the number of users, the traditional communication network architecture has gradually exposed a series of problems such as insufficient bandwidth, low transmission efficiency, and security risks when facing the demand for converged transmission of voice and data services. In the field of government and enterprise private networks, a large amount of voice communication and data interaction is required between different departments and branches, which requires extremely high stability and security of communication, and existing network facilities often cannot meet these requirements. As an important node for the flow of personnel and materials, transportation hubs need to transmit various information in real time, including dispatching instructions, monitoring data, etc. The unified transmission of voice and data is crucial to ensure smooth and safe transportation. The energy system is related to the country's energy security and stable supply. Its communication network needs to have high reliability and anti-interference capabilities to cope with complex environments and various emergencies. Emergency command places extremely high demands on the timeliness, accuracy and stability of communication. In an emergency, it is necessary to ensure the smooth transmission of voice and data in order to make decisions and allocate resources quickly.

In response to this widespread and urgent demand, FXS/FXO over fiber multiplexer multi-service voice optical transceiver stands out with its excellent performance, outstanding stability and strong business integration capabilities, becoming the core representative of the new generation of Voice over Fiber solutions.

This flexibility enables the device to be compatible with various types of terminal equipment, such as ordinary telephones, fax machines, and various switches, so as to stably carry a variety of voice services such as POTS telephones, faxes, and magnetophones, providing users with rich choices and convenient user experience.

2. Core functions: Multi-port design ensures stable and efficient communication

FXS/FXO over fiber multiplexer supports 1~8 FXS over fiber or FXO over fiber voice interfaces to meet the needs of multi-channel voice access, with strong compatibility and flexible deployment. The device provides 1 RJ45 Gigabit Ethernet interface that supports 10/100/1000M adaptive, supports VLAN, can efficiently carry high-definition video, data transmission and IP voice services, and ensure the coordinated operation of multi-service systems.

The voice optical terminal supports single-mode, dual-fiber, multi-mode or WDM fiber interfaces, with a maximum transmission distance of up to 40 kilometers, providing an ideal solution for cross-regional and cross-park scenarios. The product supports rich voice functions such as caller identification, reverse polarity billing, fax, and ringing detection, which greatly improves user experience and communication efficiency.

In order to cope with complex industrial environments, the equipment adopts industrial-grade lightning protection design, complies with IEC61000-4-5 standards, has strong anti-interference capabilities, and can operate stably in high humidity, high temperature, high electromagnetic interference and other environments. In addition, the local end has the ability to monitor the remote optical link, which can monitor the remote optical fiber connection status in real time, significantly improve the operation and maintenance efficiency, and reduce the failure rate.

3. Typical application scenarios

In the power system, FXS/FXO over fiber multiplexer can be used as a multi-channel voice and data bridge between the main control center and the substation to realize the real-time issuance of remote monitoring and dispatching instructions, and improve the intelligent level of power grid operation and maintenance.

In emergency communication command, the equipment provides clear and stable voice dispatching channels and on-site data return channels for public security, fire protection, emergency management and other departments, and is one of the core infrastructures to ensure decision-making timeliness and resource allocation capabilities.

In the urban rail transit industry, the voice optical terminal can realize multi-service integrated communications such as intercom broadcasting and operation data upload between the station and the dispatching center, effectively improving system reliability and dispatching response speed.

In terms of government and enterprise private network construction, the equipment provides a cost-effective solution for cross-regional and cross-building communication scenarios, and is particularly suitable as an E1 alternative, smoothly migrating the original analog voice system to the optical fiber network, compatible with traditional TDM voice, and ensuring a smooth transition of the original system.

In mining and industrial automation scenarios, FXS/FXO over fiber multiplexer, as a fiber-optic voice transmission device with strong anti-interference ability and convenient deployment, can ensure stable and smooth data collection and voice communication between underground and ground, and ensure personnel safety and production continuity.

4. Summary: An important bridge to promote the evolution of TDM to fiber

As the IP trend sweeps the communications industry, a large number of voice systems based on E1 and TDM architectures are still widely used in various industries. The launch of FXS/FXO over fiber multiplexer voice optical transceiver provides a stable, secure and scalable TDM over fiber evolution path for such systems.

It not only retains the stability and clarity of traditional TDM voice communication, but also significantly improves the communication quality and transmission distance by leveraging the high bandwidth and low latency advantages of optical fiber. As a multi-service optical transceiver that integrates FXS/FXO over fiber interface, Ethernet data port, and industrial-grade reliability, it has become a star model in the product lines of many optical transceiver manufacturers.
