1.25G SFP Optical Transceiver Module Series, Single-Mode Single-Fiber, 20KM – 40KM, Dual-Wavelength, DDM, SC Connector

The 1.25G SFP Optical Transceiver Module Series (Single-Mode Single-Fiber) with SC connectors delivers high-speed, long-range data transmission over single fibers. Leveraging dual-wavelength technology (1310/1550nm pairs) and DFB lasers for 40KM models, these modules enable simultaneous bidirectional communication with minimal signal loss. Integrated Digital Diagnostic Monitoring (DDM) provides real-time tracking of temperature, voltage, and optical power, ensuring proactive network management. Designed for compatibility with existing SC-based infrastructure, they are ideal for metropolitan area networks, regional data links, and enterprise backbones.

1. Metropolitan Area Networks (MANs): The 20KM modules (TV-A-20KM-SC/TV-B-20KM-SC) are ideal for connecting network nodes within cities, such as between data centers, base stations, and central offices.
2. Regional Network Backbones: The 40KM modules (TV-A-40KM-SC/TV-B-40KM-SC) support high-speed links between regional network centers, enabling efficient data transfer over longer distances.
3. Enterprise Campus Networks: Both 20KM and 40KM variants facilitate high-speed connections between buildings in large corporate or university campuses, leveraging existing SC-based fiber infrastructure.
4. Telecommunication Access Networks: These modules can be deployed in fiber-to-the-x (FTTx) networks, connecting central offices to distribution points or subscriber premises over single fibers.
5. Industrial Control Systems: The industrial temperature grade models ensure reliable communication in harsh environments, such as power plants, factories, or outdoor installations.
