Description
The AddOn NetOptics® QSFP28-LR4-XCVR-AO is a high-performance, TAA-compliant optical transceiver designed to deliver 100GBase-LR4 Ethernet connectivity over distances of up to 10km using single-mode fiber (SMF). Operating across wavelengths from 1295nm to 1309nm, it features a duplex LC connector and supports Digital Optical Monitoring (DOM) for real-time diagnostic insight into optical performance.
Engineered for access, enterprise, and data center networking, this hot-swappable QSFP28 module is SFF-8665 compliant, RoHS compliant, and lead-free, with robust ESD protection and low EMI metal housing. Each transceiver undergoes unique serialization, programming, and data-traffic testing to ensure seamless compatibility and plug-and-play performance with NetOptics® systems.
With its proven reliability and backed by AddOn’s limited lifetime warranty, the QSFP28-LR4-XCVR-AO is an ideal solution for scalable, high-speed network infrastructures.
