The Cisco Network Module is an uplink expansion module designed for network administrators who need to extend the high-speed connectivity of their switching infrastructure. Built around four QSFP28 expansion slots, it supports both 40 Gigabit Ethernet and 100 Gigabit Ethernet over Optical Fiber, delivering a maximum data transfer rate of 100 Gbit/s.
Key Features:
- Four QSFP28 expansion slots provide the physical interfaces needed to build out high-density uplink connectivity from a single module.
- Support for both 40GBase-X and 100GBase-X network technology gives administrators the flexibility to operate at either 40 Gigabit Ethernet or 100 Gigabit Ethernet speeds depending on the demands of the environment.
- A maximum data transfer rate of 100 Gbit/s allows the module to handle the throughput requirements of bandwidth-intensive switching tiers.
- Optical Fiber media support enables long-distance interconnection between switches and upstream network equipment without the limitations of copper cabling.
- Verified compatibility with the Cisco C9000 Smart Switching Platform and Cisco C9350 Series Smart Switches ensures the module integrates directly into existing Cisco deployments without additional adaptation.
Slot Configuration and Port Density
The module carries four expansion slots, each of the QSFP28 type. Each slot is rated for 40/100GBase-X operation, meaning the same physical port can be used in either a 40 Gigabit or 100 Gigabit context. This shared-rate design lets a single installed module serve network tiers running at different speeds without requiring separate hardware for each rate.
Ethernet Speed and Network Technology
The module operates across both 40 Gigabit Ethernet and 100 Gigabit Ethernet standards, using 40GBase-X and 100GBase-X network technology respectively. The maximum data transfer rate across the module reaches 100 Gbit/s, reflecting the ceiling of the 100GBase-X standard it implements.
Optical Fiber Media Support
All four ports on this module are designed for Optical Fiber connectivity. Fiber links support longer physical cable runs than copper alternatives and carry high-bandwidth signals with lower susceptibility to electromagnetic interference, making the module well suited to interconnects that span equipment cabinets or separate rooms within a facility.
Platform Compatibility
The module is confirmed compatible with the Cisco C9000 Smart Switching Platform and with Cisco C9350 Series Smart Switches specifically. Purchasing against a known compatibility list reduces integration risk and helps ensure that the module will be recognized and fully operable once installed in an eligible chassis.
