The Cisco QSFP-40G-SR-BD is a high-performance 40GBASE-SR Bi-Directional QSFP transceiver module engineered for use with Duplex Multimode Fiber (MMF). Leveraging bidirectional (BiDi) technology, this module delivers full 40G throughput over standard duplex OM3/OM4 fiber infrastructure — eliminating the need for parallel fiber cabling and reducing deployment costs significantly.
This unit is professionally refurbished and has been rigorously tested to original factory specifications by WhaleyComm's certified technicians. Each module undergoes full functional verification before shipment, ensuring enterprise-grade reliability at a fraction of the cost of new.
