The US Transceivers compatible QSFP-100G-CWDM4-S is a 100GBASE-CWDM4 QSFP28 transceiver module designed as a cost-effective, drop-in replacement for use in Cisco-compatible networking environments. This module operates over duplex single-mode fiber and supports a maximum reach of 2 km, making it well suited for campus and data center interconnect applications requiring reliable 100G throughput over intermediate distances.
Utilizing CWDM4 technology, the module transmits across four CWDM wavelengths (1271 nm, 1291 nm, 1311 nm, and 1331 nm), each carrying 25 Gbps to achieve an aggregate data rate of 100 Gbps. The LC Duplex connector interface ensures straightforward integration with standard single-mode fiber plant infrastructure. This module is TAA compliant and RoHS certified, meeting regulatory requirements for government and enterprise procurement.
The US Transceivers compatible QSFP-100G-CWDM4-S supports Digital Diagnostic Monitoring (DDM/DOM), providing real-time visibility into optical performance parameters such as temperature, voltage, TX power, and RX power for simplified network management and troubleshooting.
