Description
The AddOn Cisco® ONS-QSFP28-LR4 Compatible TAA 100GBase/OTU4-LR4 QSFP28 Transceiver (ONS-QSFP28-LR4-AO) is a high-performance optical module designed to deliver 100Gbps Ethernet and OTU4 connectivity over single-mode fiber (SMF) at distances up to 10 km. Operating across wavelengths from 1295nm to 1309nm with a duplex LC connector, this hot-pluggable transceiver ensures seamless integration into existing network infrastructures.
Engineered for telecom, wireless, access, and enterprise applications, the module provides Digital Optical Monitoring (DOM) for real-time diagnostics and adheres to industry standards including SFF-8665 and RoHS 2.0. With robust ESD protection, low EMI, and compliance with Trade Agreements Act (TAA), it is guaranteed to be 100% compatible with the original Cisco® ONS-QSFP28-LR4 transceiver. Each unit is programmed, serialized, and tested to ensure identical performance and reliability, backed by AddOn’s limited lifetime warranty.
