Description
The AddOn Cisco® QSFP-100G-LR4-S-4WDM-20-I Compatible TAA 100GBase-4WDM-20 QSFP28 Transceiver is designed to deliver high-speed, reliable 100GbE connectivity for enterprise, data center, and access networks. Supporting data rates up to 103Gbps, this hot-swappable optical transceiver operates over single-mode fiber (SMF) at wavelengths ranging from 1295nm to 1309nm and provides a transmission distance of up to 20km via duplex LC connectors.
Built with LAN-WDM DFB-based transmitters and PIN/TIA receivers, this module offers superior optical performance and energy efficiency with power consumption below 4.8W. It features Digital Optical Monitoring (DOM) for real-time performance metrics and operates across a wide industrial temperature range (-40°C to 85°C).
Fully compliant with QSFP28 MSA and IEEE 802.3 standards, this transceiver ensures seamless interoperability and is 100% guaranteed to be compatible with the equivalent Cisco® part. Each unit is TAA compliant, uniquely serialized, and tested for quality, reliability, and full OEM-equivalent performance.
