Built for standard 1000Base-SX applications, it fits into SFP slots enabling easy upgrades or expansions of fiber networks. Network engineers and IT professionals benefit from its plug-and-play compatibility and stable performance. Key Features Operates at 2.125Gbps for smooth data flow Supports multi-mode fiber with 850nm wavelength Effective communication distance of up to 550 meters Duplex LC connectors ensure simple and secure fiber hookups Complies with 1000Base-SX standards for compatibility This module is typically deployed in switches and servers to extend network reach within buildings or across campuses. It plays a practical role in maintaining fast and consistent connections between network devices without the need for copper cables.

Use Cases
The Finisar 2.125Gbps 1000Base-SX SFP transceiver is suited for IT infrastructures requiring reliable short-range fiber connectivity. It is ideal in environments where multi-mode fiber is already deployed and efficient gigabit links are needed, such as enterprise campus networks and data closet aggregation points. How It's Used: Connecting switches within data centers for high-throughput rack-to-rack fiber links. Extending network segments across university or corporate campus buildings using existing multi-mode fiber cabling. Linking storage area networks (SANs) that demand low-latency gigabit fiber connections in enterprise IT environments. Providing fiber optic connectivity in SMB networks seeking improved EMI resistance over copper alternatives. Supporting edge computing nodes requiring fiber-based uplinks in constrained physical spaces. This SFP module facilitates scalable and maintainable fiber network deployments by leveraging compact transceiver form factors. Its compatibility with standard multi-mode fiber and duplex LC connectors helps maintain consistent network performance in densely cabled infrastructure scenarios.
