Description
The AddOn Cisco® QSFP-4X10G-LR-S-AO is a 40GBase-PLR4 QSFP+ optical transceiver designed for high-performance data center, enterprise, and access networking applications. This hot-swappable module delivers up to 40Gbps throughput over single-mode fiber (SMF) at distances of up to 10 kilometers using a 1310nm wavelength and MPO connector interface.
Fully compliant with SFF-8436 and Trade Agreements Act (TAA) standards, this transceiver guarantees 100% compatibility with the original Cisco® equivalent. It features Digital Optical Monitoring (DOM) for real-time performance insights and ensures reliable operation across commercial temperature ranges (0°C to 70°C). With its robust ESD protection, low EMI metal housing, and support for RoHS lead-free standards, this module is a dependable choice for scalable network deployments.
Each unit is individually programmed, serialized, and rigorously tested for compatibility, performance, and interoperability — backed by AddOn’s limited lifetime warranty.
