Product Features
Technical Overview
This expansion module delivers essential connectivity expansion with four dedicated slots that accept industry-standard SFP and SFP+ optical transceivers. The dual-format slot support allows network administrators to mix 1GbE SFP and 10GbE SFP+ modules within the same chassis, providing granular control over port speed and media type based on specific link requirements.
The module is specifically engineered for the Cisco Catalyst 3850 Series switching platform, ensuring full electrical and mechanical compatibility. Hot-pluggable design facilitates maintenance and upgrades without disrupting switch operation, while the refurbished condition means each unit has been thoroughly tested and restored to reliable working order.
Key Product Advantages
This Cisco network module offers several distinct advantages for expanding Catalyst 3850 switch connectivity. The four-slot configuration provides balanced port density for adding optical uplinks, server connections, or inter-switch links without consuming valuable fixed ports on the switch itself.
Flexible Media Support
Support for both SFP and SFP+ transceivers allows deployment of 1GbE or 10GbE connections using singlemode or multimode fiber, copper DAC cables, or active optical cables based on distance, budget, and performance requirements.
- Mix 1GbE and 10GbE in same module
- Choose fiber type per link
- Support for DAC and AOC options
Proven Platform Integration
Designed specifically for Catalyst 3850 switches, this module ensures full compatibility with switch management, power, and cooling systems while maintaining consistent operational characteristics with other Cisco optics.
- Seamless management integration
- Guaranteed mechanical fit
- Consistent thermal performance
Deployment / Use Cases
The C3850-NM-2-10G-RF module is ideal for expanding connectivity in Catalyst 3850-based network deployments. Common applications include adding high-speed uplinks to aggregation or core switches, connecting to servers with 10GbE network interfaces, or establishing fiber connections between wiring closets and data center racks.
In campus networks, this module can provide the optical connectivity needed for backbone links between buildings while maintaining compatibility with existing SFP infrastructure. For data center deployments, the SFP+ slots enable 10GbE server connections or storage network links, with the flexibility to use cost-effective DAC cables for short reaches or fiber for longer distances.
Campus Network Expansion
Add fiber uplinks between wiring closets and network cores using singlemode fiber for long-distance connections or multimode for cost-effective intra-building links.
Data Center Server Connectivity
Connect virtualized servers and storage arrays with 10GbE links using SFP+ transceivers, with options for copper DAC cables within racks or fiber between racks.
Physical Profile
The module features a compact form factor designed specifically for Catalyst 3850 switch chassis. With a weight of approximately 11.36 ounces (322 grams), it adds minimal load to the switch while maintaining robust construction suitable for enterprise environments. The standardized dimensions ensure proper fit and alignment within the switch expansion bay, with secure mounting that withstands typical rack vibration and movement.

FAQ
What types of transceivers can I install in this network module?
This Cisco network module supports both SFP (mini-GBIC) and SFP+ transceivers in its four expansion slots. You can install 1GbE SFP transceivers for Gigabit Ethernet connections or 10GbE SFP+ transceivers for 10 Gigabit Ethernet links. The module is compatible with industry-standard Cisco and third-party transceivers that match the SFP/SFP+ form factor specifications.
Which Cisco switch models are compatible with this expansion module?
The C3850-NM-2-10G-RF network module is specifically designed for and compatible with the Cisco Catalyst 3850 Series switches. This includes all models in the Catalyst 3850 family that feature expansion module slots. The module will not work with other Cisco switch series or non-Cisco equipment due to specific electrical, mechanical, and management requirements.
What does 'refurbished' condition mean for this network module?
Refurbished condition indicates this Cisco network module has been previously used but has undergone comprehensive testing, cleaning, and restoration to ensure reliable operation. Refurbished products typically include visual inspection, functional testing, and replacement of any worn components as needed. They offer a cost-effective alternative to new hardware while maintaining compatibility and performance standards.
Can I mix different types of transceivers in the four slots?
Yes, you can mix different transceiver types across the four expansion slots. The module supports simultaneous operation of SFP and SFP+ transceivers, allowing you to configure each slot independently based on your connectivity needs. For example, you could install two 1GbE SFP transceivers and two 10GbE SFP+ transceivers in the same module, with each port operating at its designated speed.
