## Summary description

Cisco QSFP-40/100-SRBD-RFB is a QSFP optical transceiver module supporting 100G and 40GBASE SR-BiDi operation. Designed for short-reach data center links, it enables bidirectional transmission over a single multimode fiber using BiDi optics. The module fits QSFP ports and is intended for high-density switch and server connectivity in enterprise and service-provider networks.

## Long description

The Cisco QSFP-40/100-SRBD-RFB is an optical transceiver module that supports both 100G and 40GBASE SR-BiDi operation for short-reach multimode fiber links. Designed for data center environments, the module enables bidirectional transmission over a single multimode fiber using BiDi optics and fits standard QSFP ports for easy installation in high-density switches and servers.
Advantages
This QSFP transceiver reduces fiber infrastructure by enabling bidirectional communication over a single multimode fiber, simplifying cabling in dense rack deployments. Its dual-rate capability supports both 100G and 40G modes, offering flexibility when migrating between link speeds. The module conforms to QSFP form-factor dimensions for compatibility with a wide range of network equipment and is intended for reliable short-reach connectivity within enterprise and service-provider networks.
Suitable for
 Short-reach data center interconnects over multimode fiber
 High-density switch-to-switch or switch-to-server links
 Environments requiring migration between 40G and 100G link speeds
 Scenarios where minimizing fiber cabling is important
Key specifications
 Optical technology: SR-BiDi (short-range bidirectional)
 Supported link speeds: 100G and 40G
 Form factor: QSFP (Quad Small Form-factor Pluggable)
 Fiber type: Multimode fiber
 Typical application: Short-reach data center links
 Connector interface: QSFP port compatible
How to use
Insert the QSFP transceiver into a compatible QSFP port on a switch or server module until it latches securely. Connect a single multimode fiber cable with suitable duplex LC or MPO breakout (as required by system cabling) to the transceiver to enable bidirectional SR-BiDi transmission. Configure the host device for the appropriate link speed (40G or 100G) and verify link status and diagnostics via the network equipment management interface. Follow the equipment vendor guidelines for hot-plug procedures and handling precautions to avoid electrostatic damage.
Usage recommendations
Use this module for short-distance connections within data centers and ensure multimode fiber and patching hardware meet the required modal bandwidth and loss budgets. When migrating between 40G and 100G, confirm firmware and platform support for dual-rate operation and test link performance after installation.
