This collection includes a range of 40GBASE-SR4 modules that support distances of up to 100m over OM3 or 150m over OM4 multimode fiber, making them ideal for short-range top-of-rack connections. Extended-range optics such as 40GBASE‑LR4 offer up to 10 km reach over single-mode fiber, supporting campus and long-haul links. For flexibility, QSFP to 4×10G fanouts allow a single 40G port to serve multiple 10G endpoints, optimizing port utilization in clustered or mixed-speed networks.

Arista’s balanced approach includes copper-based solutions like directattach QSFP+ twinax cables for very short distances with low latency, and Universal QSFP optics that support both single-mode and multimode fiber over duplex connections. These are especially useful for those migrating from 10G to 40G without reterminating their existing cabling infrastructure.

Engineered for compatibility with platforms like the 7050X, 7280R, and 7500R series, these QSFP transceivers offer plug-and-play integration and reliable performance in production environments.

At NetworkTigers, refurbished units are tested and verified to meet performance standards, and used units are confirmed ready for production networks. Inventory is kept in stock, orders ship quickly, and each transceiver is supported by a 365-day warranty.
