Cisco Compatible QSFP-100G-LR4-S

100GBASE-LR4 QSFP28 Transceiver Module | 10km SMF | Duplex LC | CWDM4 Technology




Product Overview

The Cisco compatible QSFP-100G-LR4-S is a high-performance 100GBASE-LR4 QSFP28 optical transceiver module designed for long-range 100 Gigabit Ethernet transmission over single-mode fiber (SMF).
Using 4-channel CWDM optical technology, the module multiplexes four optical wavelengths onto a duplex LC fiber pair, enabling reliable 100Gbps transmission up to 10 kilometers over standard single-mode fiber.
The QSFP-100G-LR4-S is ideal for:
  • Data center interconnects (DCI)
  • Enterprise campus backbone networks
  • Metro transport networks
  • Cloud computing infrastructure
  • ISP and telecom aggregation networks
  • High-performance computing (HPC)
Compared with SR4 or CWDM4 modules, LR4 provides significantly longer transmission distance while maintaining compact QSFP28 high-density deployment.



Key Features

  • Supports 100GBASE-LR4 Ethernet
  • QSFP28 hot-pluggable form factor
