QSFP-100G-FR-S

The Cisco QSFP-100G-FR-S is a high-speed transceiver module designed to deliver 100 Gigabit Ethernet over single-mode fiber. It’s built for network environments that require reliable, long-distance data transmission while maintaining compact hardware footprints.

Often found in data centers and enterprise networks, this module provides efficient connectivity between switches and routers across moderate distances. Network engineers and system integrators typically rely on this module to extend network reach without sacrificing performance.

Key Features

• Operates at 1310nm wavelength optimized for single-mode fibers
• Supports duplex LC connectors for straightforward fiber connections
• Compatible with QSFP28 ports for easy integration with modern hardware
• Ensures up to 2km reach, suitable for various campus and metropolitan networks
• Meets the 100GBase-FR1 standard for long-reach Ethernet applications

In practice, this transceiver is used to connect equipment across buildings, floors, or data center aisles where distances exceed typical short-range modules. It helps maintain stable, high-speed links in environments that balance reach and bandwidth requirements without complex setups.
