The64 channel telephone optical transceivers support the selection and customization of 1 to N telephone interfaces, reducing procurement and deployment costs; they are compatible with FXO/FXS interfaces and support functions such as call display, suitable for enterprise communication, expansion of switching centers, elevator intercom, and other scenarios.
2. High-definition voice transmission, stable and interference-free:
The64 channel telephone optical transceivers employ PCM encoding technology, with 64Kbps uncompressed transmission, ensuring clear and noise-free calls without any delay. Leveraging the advantages of optical fibers, 64 channel telephone optical transceivers completely avoid electromagnetic and radio frequency interference, and are suitable for complex environments such as industrial control, meeting the needs of emergency and daily office communication.
The total bandwidth of 64 channel telephone optical transceiver is 155M - 250M. It supports single/fiber or dual-fiber transmission. For multimode, they can transmit up to 2KM, and for single mode, the maximum transmission distance is 120KM, without the need for repeaters. The bandwidth redundancy is sufficient, enabling it to simultaneously carry telephone, 100M Ethernet, and E1 services, achieving"one line for multiple uses".
4. Stable, reliable and durable, with extremely low operation and maintenance costs:
The64 channel telephone optical transceivers are designed with large-scale integrated circuits, featuring low power consumption and energy-saving durability. 64 channel telephone optical transceivers support dual power supply options, and some models have hot-swappable and 1+1 backup functions to ensure business continuity. The standard chassis installation is convenient, and they are equipped with alarm indication and network management interfaces, making operation and maintenance efficient.
5. Strong compatibility and easy scalability, with convenient and efficient deployment:
The64 channel telephone optical transceivers are compatible with mainstream switches, PCM devices, etc., and can seamlessly integrate into the existing network; the modular design reserves slots, allowing for flexible expansion in the future without the need to replace the entire machine; standardized interfaces make wiring simple and plug-and-play, shortening the deployment cycle.
In today's era of rapid evolution of optical fiber communication technology, the 64 channel telephone optical transceivers, as the core carrier for long-distance transmission of voice signals, have already permeated into the communication networks of various industries. As a direct supply product from the manufacturer, our 64 channel telephone optical transceivers have outstanding core advantages and can ensure communication security.
First, they are flexible and adaptable. According to the differentiated needs of various industries, the 64 channel telephone optical transceivers adopt a modular design. The number of channels can be customized from 1 to N. They can be equipped with Ethernet, E1, serial data and other interfaces, and 64 channel telephone optical transceivers support mixed transmission of multiple services, suitable for all scenarios such as communities, enterprises, operators, and mines. Second, they are stable and reliable. The 64 channel telephone optical transceivers use dedicated digital multiplexing chips and all-digital circuit design, with a low failure rate. They have a complete alarm monitoring function and can be equipped with dual power supplies and dual optical port backups to ensure uninterrupted communication. Third, they offer high-definition transmission. They have multiple protections. The 64 channel telephone optical transceivers use G.711 encoding law, which complies with international standards, ensuring that the call has no noise and no delay. The telephone interface is equipped with lightning protection and overvoltage protection, and the optical interface supports single/fiber transmission. Some models can have an internal SNMP module, making centralized management convenient.
With the integration of 5G and fiber-optic communication, we will continuously optimize the performance of 64 channel telephone optical transceivers, expand their specifications and application scenarios. By providing high-quality 64 channel telephone optical transceivers, comprehensive services and competitive prices, we aim to assist our customers in upgrading their communication networks, enabling seamless long-distance communication and making maintenance more convenient.
