Description
The AddOn Cisco® QSFP-100G-LR4-S-AO is a high-performance, hot-pluggable QSFP28 transceiver designed to deliver reliable 100GBase-LR4 Ethernet connectivity over single-mode fiber (SMF) up to 10 km. Operating across wavelengths from 1295 nm to 1309 nm, it features a duplex LC connector and supports Digital Optical Monitoring (DOM) for real-time diagnostics.
Engineered for data center, enterprise, and access networks, this module ensures 100% compatibility with Cisco® OEM devices and meets stringent SFF-8665 standards. It is TAA compliant, RoHS certified, and offers excellent EMI shielding, low power consumption, and robust ESD protection.
Each transceiver is individually programmed, serialized, and application-tested to guarantee seamless network integration and identical initialization performance to the original Cisco® unit. AddOn stands behind its quality with a limited lifetime warranty.
