Cisco Compatible QSFP-100G-LR-S

100GBASE-LR1 QSFP28 Transceiver Module | 10km Single-Mode Fiber | LC Duplex | PAM4



Product Overview

The Cisco compatible QSFP-100G-LR-S is a high-performance 100GBASE-LR1 QSFP28 optical transceiver module designed for long-reach 100 Gigabit Ethernet transmission over single-mode fiber (SMF).
Built on single-lambda (LR1) PAM4 technology, this module delivers 100Gbps data transmission over a single optical channel, enabling simplified, cost-efficient, and high-performance 100G networking.
The QSFP-100G-LR-S supports transmission distances up to 10 kilometers over single-mode fiber, making it ideal for:
  • Data center interconnect (DCI)
  • Enterprise campus backbone networks
  • Metro aggregation networks
  • Cloud infrastructure
  • Carrier and service provider networks
  • High-performance computing (HPC)
Compared with multi-lane LR4 optics, LR1 reduces optical complexity while maintaining long-reach capability and simplified duplex LC infrastructure.
