## Summary description

The Cisco QSFP-40G-SR-BD is a fiber optic network transceiver module with a maximum data transfer rate of 40000 Mbit/s at 850 nm. It features a QSFP interface and typical power consumption of 3.5 W. This MSA certified module is ideal for high-speed data applications, providing reliable performance and efficiency in data centers and enterprise networks.

## Long description

The Cisco QSFP-40G-SR-BD is a fiber-optic network transceiver module that supports data rates up to 40 Gbit/s over multimode fiber at an 850 nm wavelength. The module uses a QSFP form factor, is MSA certified, and typically consumes around 3.5 W, making it suitable for high-density, energy-conscious deployments in data centers, enterprise networks, and service-provider environments.
Advantages
The transceiver is hot-swappable and plugs into standard 40 Gigabit Ethernet QSFP ports, offering flexibility for different reach requirements and fiber types. It complies with IEEE 802.3ba electrical interface requirements and follows SFF-8436 and QSFP MSA specifications for form factor and low-speed management interfaces. The module is certified and tested on Cisco 40G QSFP ports to ensure compatibility, performance, and reliability, and it is interoperable with other IEEE-compliant 40GBASE interfaces when applicable.
Suitable for
Data center interconnects and server-to-switch links
High-performance computing clusters and storage networks
Enterprise core and distribution layer connectivity
Service provider aggregation and metro applications
Key specifications
Product: Cisco QSFP-40G-SR-BD
Form factor: QSFP (Quad Small Form-Factor Pluggable)
Data rate: 40 Gbit/s (40GBASE)
Wavelength: 850 nm (multimode fiber)
Typical power consumption: 3.5 W
Standards compliance: IEEE 802.3ba; SFF-8436; QSFP MSA
Certification: MSA certified; tested on Cisco QSFP 40G ports
How to use
Insert the QSFP-40G-SR-BD module into a compatible 40G QSFP port on a switch or host interface while the device is powered according to the equipment manual; the module supports hot-swapping. Connect the appropriate MPO/MTP multimode fiber patch cable or breakout cable per your port configuration and link distance requirements. Configure the network device port settings as required by your operating system or switch firmware to enable 40G operation and monitor link status through the device management interface.
Usage recommendations
Use multimode fiber that meets the specified OM standard for the desired reach and verify polarity and connector type before installation. Ensure firmware and platform compatibility by consulting Cisco interoperability documentation and perform link tests after installation to confirm expected performance.
