1.25G SFP Optical Transceiver Module, Single-Mode Single-Fiber, 40KM – 160KM, Multi-Wavelength, DDM, LC Connector

The 1.25G SFP Bidirectional Optical Transceiver Module Series (Single-Mode Single-Fiber) offers high-performance, long-haul data transmission solutions with versatile wavelength configurations. Ranging from 40KM to 160KM, these modules leverage advanced DFB/FP laser technologies and dual-wavelength pairs (1310/1550nm, 1310/1490nm, 1490/1550nm) to enable bidirectional communication over single fibers. Integrated Digital Diagnostic Monitoring (DDM) provides real-time monitoring of critical parameters, ensuring optimal network performance. Designed for compatibility with standard LC connectors, they are ideal for metropolitan, regional, and national network backbones, as well as data center interconnections.

• Regional Network Backbones: 40KM modules (TV-A-40KM/TV-B-40KM) are ideal for connecting network nodes across cities or regions, supporting high-speed data transfer between regional data centers and network hubs.
• Inter-City and National Networks: 80KM and 120KM modules (TV-A-80KM/TV-B-120KM) enable long-haul connections between cities or across countries, forming the backbone of national and international communication networks.
• Critical Infrastructure Links: The 160KM modules (TV-A-160KM/TV-B-160KM) are designed for mission-critical applications, such as connecting remote data centers, financial networks, or emergency response systems.
• Fiber-to-the-x (FTTx) Networks: 40KM modules with 1310/1490nm wavelengths (TV-C-40KM/TV-D-40KM) are optimized for distribution networks in FTTx deployments, connecting central offices to remote nodes.
• Data Center Interconnects: All models support high-speed links between data centers, enabling efficient data replication, cloud service integration, and disaster recovery.
