1.25G SFP Optical Transceiver Module Series, Single-Mode Single-Fiber, 3KM – 20KM, Dual-Wavelength, DDM, LC Connector

The 1.25G SFP Optical Transceiver Module Series (Single-Mode Single-Fiber) delivers high-speed, cost-effective data transmission over short to medium distances. Leveraging dual-wavelength technology (1310/1550nm or 1310/1490nm pairs), these modules enable simultaneous bidirectional communication over a single fiber, doubling bandwidth efficiency. Designed with Digital Diagnostic Monitoring (DDM), they provide real-time tracking of temperature, voltage, and optical power for proactive network management. The SFP form factor ensures seamless integration with existing network infrastructure, making them ideal for metropolitan area networks, data center links, and fiber-to-the-x (FTTx) deployments.

1. Intra-Building Links: The 3KM modules are ideal for high-speed connections between network equipment within large buildings, such as data centers, office complexes, or hospitals.
2. Metropolitan Area Networks (MANs): The 20KM variants enable cost-effective links between city-based network nodes, including switches, routers, and base stations.
3. Fiber-to-the-x (FTTx) Deployments: Modules like TV-C-20KM/TV-D-20KM support bidirectional communication in access networks, connecting central offices to subscriber premises over single fibers.
4. Campus Networks: 20KM modules facilitate high-speed connections between buildings in university or corporate campuses, optimizing fiber infrastructure usage.
5. Data Center Interconnects: The 3KM and 20KM modules support short to medium-range links between data centers, server racks, or storage arrays, ensuring efficient data transfer.
