This collection features a variety of SFP28 25G optics tailored for different deployment scenarios. Short reach SR modules support multimode fiber in top-of-rack configurations, delivering fast and cost-effective connectivity inside data halls. Long reach LR options extend to single-mode fiber, making them suitable for aggregation or inter-building links. ER and extended-range optics offer even greater flexibility for campus or metro applications that require covering longer distances without compromising throughput.

With line-rate 25G bandwidth, these modules allow enterprises to migrate from 10G to higher speeds efficiently, supporting demanding workloads such as virtualization, cloud applications, and AI-driven compute clusters. Each SFP28 is engineered for consistent performance with low latency, low power consumption, and full standards compliance, ensuring interoperability across 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 for rapid fulfillment, orders ship quickly, and every transceiver is backed by a 365-day warranty.
