The Cisco QSFP-40G-SR-BD is a refurbished 40GBASE-SR Bi-Directional QSFP optical transceiver designed for duplex multimode fiber connections. Using a unique bidirectional technology over a single pair of fibers, it transmits and receives simultaneously on the same strand, providing high-speed 40Gbps connectivity without additional fiber runs.

Operating across wavelengths from 832 to 918nm, this hot-swappable module supports cable distances of up to 30m on OM2, 100m on OM3, and 150m on OM4 fiber. It is fully compliant with IEEE 802.3 standards and QSFP+ MSA specifications, making it ideal for high-density data center deployments and enterprise backbone networks.


✔ Key Features & Benefits

✔ 40GBASE-SR BiDi technology allows 40Gbps over a single duplex MMF pair
✔ Supports up to 150m over OM4, 100m over OM3, and 30m over OM2 fiber
✔ Operates over wavelengths from 832nm to 918nm
✔ Low power consumption of 3.5W for energy-efficient operation
✔ QSFP+ hot-swappable form factor for quick deployment and replacement


✔ Ideal Uses

✔ Data center backbone and aggregation layer links
