Cisco Compatible QSFP-100G-FR-S

100GBASE-FR QSFP28 Transceiver Module | 2km Single-Mode Fiber | LC Connector | PAM4



Product Overview

The Cisco compatible QSFP-100G-FR-S is a high-performance 100GBASE-FR QSFP28 optical transceiver module designed for medium-reach 100 Gigabit Ethernet connectivity over single-mode fiber (SMF).
Using advanced PAM4 modulation technology, the QSFP-100G-FR-S delivers 100Gbps transmission over a single wavelength, enabling efficient, simplified, and cost-effective 100G deployment across modern data center and enterprise networks.
The module supports transmission distances up to 2 kilometers over single-mode fiber, making it ideal for:
  • Data center interconnects
  • Campus backbone networks
  • Cloud infrastructure
  • Enterprise core networking
  • High-performance computing (HPC)
  • Metro edge aggregation links
Compared with short-reach SR or DR optics, the FR series extends reach while maintaining simplified single-lane architecture and low power consumption.


Key Features

  • Supports 100GBASE-FR Ethernet
  • QSFP28 hot-pluggable form factor
