Description
The AddOn QSFP28-100GB-LR4-AO is a high-performance, MSA-compliant optical transceiver designed to deliver reliable 100GBase-LR4 Ethernet connectivity up to 10 km over single-mode fiber (SMF). Operating within a wavelength range of 1295 nm to 1309 nm, this module uses a duplex LC connector and supports Digital Optical Monitoring (DOM), providing real-time access to operating parameters for enhanced network visibility.
Built with hot-pluggable functionality, robust ESD protection, and low EMI metal housing, this transceiver ensures seamless integration into enterprise, data center, and access network environments. Each unit is uniquely serialized, fully tested for data traffic and application compatibility, and backed by a limited lifetime warranty. Additionally, it is Trade Agreements Act (TAA) compliant, making it ideal for government and enterprise applications that require secure, compliant hardware.
