This collection includes a range of 400G modules built for different deployment scenarios. SR8 modules support multimode fiber and short-reach connections inside data halls, perfect for top-of-rack and spine links. DR4 and FR4 variants extend to single-mode fiber for longer distances up to 2 kilometers and beyond, while LR and ER modules push connectivity across metro or inter-campus applications. Breakout support allows one 400G port to divide into 4x100G channels, maximizing flexibility across aggregation and access tiers.

Designed for use with Arista switch families like the 7280R3, 7320X, and 7368X4, these transceivers combine high density with standards compliance, ensuring smooth interoperability. Their efficient power usage and low latency make them well suited for modern workloads where bandwidth demand continues to grow.

At NetworkTigers, refurbished units are tested and verified to meet performance standards, and used units are confirmed ready for production networks. Inventory is maintained in stock for rapid fulfillment, orders ship quickly, and a 365-day warranty backs every transceiver.
