Description
This Cisco® QSFP-100G-LR4-S-20-I compatible QSFP28 transceiver from AddOn delivers reliable 100GBase-LR4 Ethernet connectivity over single-mode fiber (SMF) for distances up to 20km. Operating across wavelengths from 1295nm to 1309nm, it uses a standard duplex LC connector and is fully hot-pluggable for simplified deployment. Engineered for industrial environments, it operates in a wide temperature range of -40°C to 85°C and includes Digital Optical Monitoring (DOM) for real-time diagnostics. Built to meet or exceed OEM specifications, each transceiver is programmed, serialized, and rigorously tested for seamless interoperability. TAA compliance ensures suitability for government and enterprise networks requiring Trade Agreements Act-certified components.
