Cisco QSFP-40/100-SRBD BiDi Transceiver Module

Cisco QSFP-40/100-SRBD BiDi Transceiver Module

The Cisco QSFP-40/100-SRBD is a bidirectional (BiDi) QSFP transceiver that supports both 40GbE and 100GbE operation over a single multimode fibre (MMF) duplex LC connection. Designed for high-density data centre environments, it eliminates the need for MPO/MTP cabling by leveraging existing duplex LC infrastructure — making it a cost-effective upgrade path from 10G to 40G or 100G.

• Part Number: QSFP-40/100-SRBD
• Speed: 40GbE / 100GbE (dual-rate)
• Connector Type: Duplex LC
• Cable Type: Multimode Fibre (MMF)
• Wavelengths: 832nm (TX) / 914nm (RX) — BiDi
• Max Reach: Up to 100m (OM4 MMF)
• Form Factor: QSFP28
• Compatibility: Cisco Nexus 9000, 3000 series and other QSFP28-capable platforms
• Standards: IEEE 802.3ba (40GbE), IEEE 802.3bm (100GbE)

Perfect for organisations migrating to 100G without rewiring — simply swap out your existing duplex LC transceivers and gain a significant bandwidth boost. Cisco-coded for seamless plug-and-play compatibility.
