About This Part
The Arista XVR-10079-20 is a high-performance QSFP28 optical transceiver designed for 100 Gigabit Ethernet applications. As part of Arista's extensive portfolio of optical modules, this Part Number XVR-10079-20 adheres to the QSFP28 form factor, ensuring compatibility with a wide range of industry-standard networking equipment. Its primary function is to facilitate high-speed, point-to-point data transmission over single-mode fiber optic cables. Specifically, it operates as a 100GBASE-PSM4 module, leveraging four independent transmit and receive channels, each carrying 25Gbps, to achieve an aggregate data rate of 100Gbps. The module is engineered for a reach of up to 2 kilometers, utilizing a 1550nm wavelength (as per product specifications) and connecting via an MPO (Multi-fiber Push On) connector. This design makes it an ideal solution for medium-reach interconnects requiring robust and efficient 100G bandwidth. This Arista QSFP28 transceiver is predominantly deployed in critical network infrastructure environments such as large-scale data centers, enterprise networks, and cloud computing facilities. It is seamlessly integrated into Arista switches and routers equipped with QSFP28 ports, enabling high-density 100G uplinks and inter-switch links. Key use cases include data center interconnects (DCIs), spine-leaf architectures, and high-bandwidth aggregation layers where reliable and low-latency 100G connectivity is paramount. Industries benefiting from this technology span telecommunications, financial services, and hyperscale cloud providers who require robust solutions to support increasing traffic demands driven by virtualization, big data analytics, and AI workloads. The XVR-10079-20 effectively solves the challenge of extending 100G reach beyond short-distance intra-rack connections, offering a cost-effective upgrade path from legacy 40G infrastructure or shorter-reach 100G variants.
