Connects a multimode Gigabit Ethernet fiber optic network cable to a Cisco switch or server’s QSFP-DD port.

  • QSFP-DD transceiver module 100% compatible with Cisco’s equivalent module
  • Provides 400 Gbps throughput up to 100 m via multimode fiber cabling
  • 16-strand MPO/APC connector supports 400GBase-SR8 signal at 850 nm wavelength
  • Hot-swappable interface lets you install and uninstall without shutting down
  • Supports DDM for monitoring temperature and other real-time operating parameters
  • 3-year limited warranty


QSFP-DD Transceiver for Connecting to Your Cisco Network Switch or Server
This QSFP-DD transceiver allows you to connect a multimode fiber optic cable to a 400 Gbps network router, server or switch. It transmits data up to 100 meters (328 feet) using an 850 nm wavelength. The zinc housing protects against electromagnetic interference (EMI) and excessive power dissipation.

Functionally Equivalent to Cisco 400GBASE-SR8 Transceiver Module
The MSA-compliant N286-400G-SR8-C functions just like the equivalent Cisco 400GBASE-SR8 transceiver module and is manufactured to meet or exceed Cisco specifications. You can use this transceiver with any compatible Cisco router, server or switch and receive the same performance as the 400GBASE-SR8.

Hot-Swappable for Installation Without Network Interruption
This input/output device is fully hot-swappable, so you can install it without a potentially costly 400 Gbps network shutdown or device reboot. Just plug the QSFP-DD end of the transceiver into your Cisco network device. The other end has an MPO/APC connector to link with multimode fiber optic cable (sold separately). A push/pull tab connector is easily accessible in high-density data center applications and makes the plug-and-play transceiver easy to install and remove with one hand.

Supports Digital Diagnostic Monitoring (DDM) for Real-Time Status Monitoring
DDM support lets you keep track of operating information in real time, such as transceiver temperature, input and output power and supply voltage.
