QSFP-4X10G-LR-S Cisco 40Gbps QSFP+ MPO Transceiver 10km Single-Mode Fiber

The Cisco QSFP-4X10G-LR-S is a high-speed transceiver module that breaks down a 40 Gbps signal into four 10 Gbps lanes, enabling fast and efficient data transmission over long distances. It’s often found in environments that require reliable, high-bandwidth connections, such as data centers and telecom infrastructure.

Built for network engineers and IT professionals, this module fits into QSFP+ ports and connects using an MPO interface, making it suitable for scalable network setups. It’s commonly used to link switches, routers, and other network devices that need to handle heavy traffic loads without compromising performance or distance.

Key Features

• Supports up to 10 km transmission over single-mode fiber
• Operates at 40 Gbps with four independent 10 Gbps channels
• Utilizes MPO multi-fiber connectors for streamlined cabling
• Compatible with standard QSFP+ form factor ports
• Built to work reliably in high-density network environments

This transceiver is typically deployed in large-scale data centers and telecom networks where long-distance, high-speed data links are essential. It helps maintain efficient communication between critical network components, reducing latency and bottlenecks.

By integrating this transceiver, network operators can extend their reach without sacrificing speed, making it a practical choice for expanding network infrastructure.
