Cisco Compatible QSFP-100G-CWDM4-S
100GBASE-CWDM4 QSFP28 Transceiver Module | 2km SMF | LC Duplex | PAM4 CWDM Technology
Product Overview
The Cisco compatible QSFP-100G-CWDM4-S is a high-performance 100GBASE-CWDM4 QSFP28 optical transceiver module designed for medium-reach 100 Gigabit Ethernet transmission over single-mode fiber (SMF).
It uses Coarse Wavelength Division Multiplexing (CWDM) technology combined with PAM4 modulation to transmit 100Gbps data over four wavelengths through a duplex LC connector, enabling efficient and cost-effective 100G connectivity.
The module supports transmission distances up to 2 kilometers over single-mode fiber, making it ideal for:
- Data center interconnects
- Enterprise backbone networks
- Cloud infrastructure
- Metro edge aggregation
- High-performance computing (HPC)
- Hyperscale data centers
Compared with PSM4 or DR solutions, CWDM4 provides better wavelength efficiency and extended reach while maintaining compatibility with duplex LC fiber infrastructure.
