Description
The Arista QSFP-XSR4 transceiver module is engineered to deliver high-speed 40 Gigabit Ethernet connectivity over multimode fiber. It leverages the QSFP+ form factor, which is a compact, hot-pluggable module designed for high-density switch and router deployments. This transceiver is optimized for short-reach applications, making it ideal for data center interconnects and within-rack cabling. Operating at a wavelength of 850nm, the QSFP-XSR4 utilizes MTP/MPO connectors, which are standard for parallel optics and support multiple fiber strands within a single connector. This allows for higher bandwidth density and simplified cable management compared to traditional duplex connectors. The module is compliant with relevant IEEE standards, ensuring interoperability with other networking equipment. Key features include support for Digital Diagnostic Monitoring (DDM), which provides real-time monitoring of critical parameters such as temperature, voltage, and optical power. This capability is essential for network administrators to troubleshoot and maintain optimal performance. The 300-meter reach over multimode fiber makes it a cost-effective solution for demanding short-distance networking needs.
