Description
The AddOn Q28-100G-LR4X2-AO is a high-performance MSA- and TAA-compliant QSFP28-DD optical transceiver designed to deliver dual 100G Ethernet connectivity for next-generation data center, enterprise, and carrier networks. Supporting a total data rate of up to 206Gbps with an 8x25Gbps electrical interface, this transceiver provides two independent 100GBase-LR4 channels over single-mode fiber (SMF) for distances up to 10km. It operates on LAN-WDM wavelengths from 1295nm to 1309nm and utilizes a dual CS connector for high-density deployment. Featuring integrated Digital Diagnostic Monitoring (DOM) via an I2C interface, the module allows real-time access to critical parameters, ensuring reliable network performance. With low power dissipation, RoHS-6 compliance, and a commercial operating temperature range, it’s engineered for seamless integration into high-speed networks where reliability and performance are essential.
