Description
The AddOn QSFP28-100GB-4WDM20-I-AO is a high-performance 100GBase-4WDM-20 QSFP28 optical transceiver designed for 100GbE data center, enterprise, and access network applications. Fully compliant with QSFP28 MSA standards, this module delivers up to 103Gbps throughput over single-mode fiber (SMF) with a reach of up to 20km using LAN-WDM wavelengths from 1295nm to 1309nm and duplex LC connectivity. It features a 4x25G electrical interface, low power consumption under 4.8W, and an integrated digital diagnostic monitoring (DOM) interface for real-time performance insights.
Built with four DFB-based LAN-WDM transmitters and a PIN/TIA receiver array, this ruggedized transceiver is engineered to operate reliably in extended temperature environments from -40°C to 85°C. Each unit is uniquely serialized, data-traffic tested, and Trade Agreements Act (TAA) compliant, ensuring seamless integration into your network infrastructure with guaranteed reliability and long-term support.
