This collection includes a wide range of QSFP28 100G optics to fit different deployment needs. Short reach SR4 modules are optimized for multimode fiber inside the data hall, enabling high-capacity connections across racks with minimal latency. For longer single-mode fiber runs, LR4 modules extend connectivity up to 10 kilometers, while ER4 and ZR4 variants push reach even further, supporting metro and inter-building links. Breakout support is also available, allowing a single 100G port to connect as 4x25G channels for maximum flexibility.

These transceivers are designed to pair with Arista switch families like the 7060X, 7280R, and 7500R, ensuring smooth interoperability across high-performance architectures. With efficient power use and full compliance to IEEE and MSA standards, QSFP28 optics make scaling to 100G straightforward and cost effective.

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 for fast fulfillment, orders ship quickly, and a 365-day warranty covers every transceiver.
