QSFP-40G-SR-BD= Overview
The QSFP-40G-SR-BD= is a high-performance Cisco QSFP+ transceiver designed to deliver reliable 40-Gigabit Ethernet connectivity over multimode fiber using bi-directional technology. This Cisco QSFP-40G-SR-BD= module supports 40GBASE-SR-BD applications, enabling seamless deployment across enterprise networks, data center fabrics, and high-density cloud environments. With its dual-wavelength design, it achieves 40G transmission over existing duplex MMF infrastructure up to 100 meters on OM3 fiber and 150 meters on OM4 fiber, eliminating the need for new parallel fiber installations.
Engineered for maximum compatibility and consistent signal integrity, the QSFP 40G SR BD= module offers low-latency data transmission, high throughput, and plug-and-play installation across Cisco platforms. Its hot-swappable design allows fast integration or replacement without network interruption, providing a cost-effective migration path from 10G to 40G using current multimode fiber systems.
