Cisco 40GBase-SR Bi-Directional QSFP Module, QSFP-40G-SR-BD

This Cisco transceiver module is bi-directional and made to work with quad small form factor pluggable (QSFP) equipment. It is built for 40G networking, making it as fast and advanced as anything on the market, and it supports multiple fiber connection modes.

The transceiver words with two 20G channels that function via OM3 and OM4. These channels can transmit and receive on the same strand and at the same time (using multimode fiber).

They are ideal for migrating to 40G from 10G. The modules allow you to upgrade the signal across your existing cabling infrastructure, one component at a time if needed.

Empowering Fast Networks

These fast modules can handle networks up to 100 meters over OM3 and 150 meters over OM4. With so many options for your high-density modules, the 40GBASE bi-directional modules free up networking design options.

You can expand your network, improve its bandwidth, and build for future traffic, all while optimizing your use of existing infrastructure.


  • Hot-swappable configuration plugs into 40G Ethernet
  • Works with other IEEE compliant 40G BASE technology
  • IEEE 802.3ba standard for high-speed electrical interface
  • QSFP form factor for low-speed electrical interface
  • Complies with QSFP MSA specifications
