QSFP-40G-SR-BD Description
QSFP-40G-SR-BD is a Cisco 40GBASE-SR BiDirectional QSFP+ optical transceiver designed for fast, cost-effective 40G Ethernet migration. Known as the "Cisco 40G BiDi module" or "40GBASE-SR-BD QSFP+," it allows customers to leverage existing 10G duplex multimode fiber infrastructure for 40G connectivity without the need for new cabling. The module operates over OM3, OM4, or OM5 multimode fiber using a standard duplex LC connector, supporting up to 100 meters on OM3 and 150 meters on OM4/OM5. With two bidirectional channels in the 832–918nm range, it delivers 40G speeds while simplifying data center and enterprise network upgrades. It is ideal for environments seeking maximum fiber reuse, reduced cost, and straightforward deployment, and complies with the QSFP MSA specification for broad compatibility.

Key Features
- Application Scenarios:
- Rapid 10G to 40G migration in data centers reusing existing duplex MMF cabling.
- Ideal for high-density server and switch uplinks in environments where re-cabling is costly or disruptive.
- Perfect for legacy enterprise and campus networks upgrading core links to 40G.
- Functional Differences:
- Uses BiDirectional technology (2x20G channels over duplex LC), allowing 40G transmission over standard 10G MMF infrastructure.
- Supports up to 100m (OM3) / 150m (OM4/OM5).
- Does not support 4x10G breakout or FCoE.
- Higher power consumption (3.5W) compared to standard SR4 modules.
Applications Scenarios
Data Center Upgrades
Enables quick 10G to 40G upgrades in data centers by reusing existing duplex MMF cabling, saving cost and time.
Enterprise Campus Core
Perfect for core or aggregation links in enterprise networks needing high bandwidth with minimal re-cabling.
Cloud & Hosting Providers
Facilitates rapid scaling and high-density connections with reduced infrastructure changes.
