Description
The AddOn Cisco® QSFP28-100GB-CLR4-C-AO is a high-performance 100GBase-CLR4 QSFP28 optical transceiver designed for data center, enterprise, and telecom environments demanding reliable, high-speed connectivity. Supporting up to 100Gbps throughput over single-mode fiber (SMF) with a maximum reach of 2km at a 1310nm wavelength, this transceiver uses a duplex LC connector for seamless integration into existing infrastructure.
Engineered for full compatibility with Cisco® hardware, this hot-swappable, plug-and-play module features a 4x25Gbps CWDM transmitter and advanced PIN/TIA receiver technology, ensuring low power consumption (<3.5W) and superior signal integrity. Digital Optical Monitoring (DOM) enables real-time diagnostics, while TAA compliance ensures suitability for government and regulated deployments. Each unit is programmed, serialized, and rigorously tested to meet or exceed OEM specifications, ensuring reliable operation and consistent performance.
