SFP Module 1.25G 40KM 1310+1490 SC Single Mode (Pair) – NETLINK
Reliable, Long-Distance Single Fiber Optical Modules with SC Interface for Efficient Network Expansion
The NETLINK SFP Module 1.25G 40KM 1310+1490 SC Single Mode (Pair) is a high-quality optical transceiver solution designed for cost-effective, high-speed data transmission over long-distance single-mode fiber (SMF). Operating at 1.25Gbps, this pair of SFP (Small Form-factor Pluggable) modules utilizes Wavelength Division Multiplexing (WDM) technology, allowing full-duplex communication over a single optical fiber. It is the perfect choice for telecom service providers, data centers, ISPs, and enterprise networks looking for efficient long-haul connectivity.
With a transmission range of up to 40 kilometers, the SFP pair provides stable and reliable data communication across extended distances, making it ideal for metropolitan area networks (MANs), FTTH deployments, backbone infrastructure, and inter-building connectivity.
Bi-Directional Transmission over a Single Fiber
This SFP module pair supports bidirectional (BiDi) transmission, which allows simultaneous data send and receive operations over a single strand of fiber. One module transmits at 1310nm and receives at 1490nm, while its paired module transmits at 1490nm and receives at 1310nm. This configuration ensures efficient use of existing fiber infrastructure, reducing deployment costs and improving overall cable management.
Whether you’re expanding an ISP backbone or building a smart enterprise network, this solution allows you to double network capacity without laying additional fiber.
Stable 1.25Gbps Data Rate for Gigabit Applications
These modules support a 1.25Gbps data rate, making them suitable for a variety of Gigabit Ethernet applications including point-to-point links, media conversion, and FTTx networks. They deliver reliable high-speed performance with low latency, ensuring seamless data transmission for both business-critical and consumer-grade services.
SC Connector – Rugged and Reliable
Equipped with an SC (Subscriber Connector) interface, this SFP module pair provides a secure and simple push-pull connection ideal for field deployments. The SC connector is widely used in telecom and networking applications due to its ruggedness and ease of use. Its single-fiber design makes it particularly beneficial for long-range deployments where minimizing fiber usage is crucial.
