Keep high-speed switch links compact and efficient with this 100GBASE-SR BIDI compatible QSFP module. It is designed for 100 GbE deployments that need to move traffic across duplex multimode fiber instead of higher-fiber-count cabling, helping reduce pathway congestion in crowded racks and aggregation layers. The QSFP28 form factor fits modern 100G switching platforms and supports short-reach optical connectivity for data center interconnects, leaf-spine fabrics, and top-of-rack uplinks. For teams standardizing on Arista-compatible optics, this module offers a practical way to maintain link density without paying for unnecessary reach. This is the kind of transceiver you choose when the network design is already disciplined and the optics need to match it: short reach, high throughput, and a clean fit into existing 100G infrastructure. It is well suited to environments where every port, strand, and rack unit has a cost.
