Suitable for trunking, uplinks and server connections requiring low-latency, short-distance fiber links.

## Long description

Cisco SFP-10G-SR-RFB is a 10GBASE-SR small form-factor pluggable (SFP+) optical transceiver designed for multimode fiber at an operating wavelength of 850 nm. It delivers 10 Gbps short-range connectivity for compatible switches, routers and network equipment, providing a compact, hot-swappable interface for data center and enterprise networking environments. The module supports short-distance fiber links with low latency and is intended for deployment in uplinks, server connections and aggregation links where multimode fiber infrastructure is used.
Advantages
The SFP-10G-SR-RFB offers a standardized SFP+ form factor that simplifies installation and replacement, while reducing inventory complexity. Its 10 Gbps throughput and 850 nm multimode design enable high-bandwidth, low-latency links over short distances. The transceiver is hot-pluggable and compatible with a wide range of 10G-capable networking equipment, allowing straightforward integration into existing multimode fiber runs. Built to industry optical specifications, it supports stable signal performance for common data center and enterprise scenarios.
Suitable for
 Short-range 10 Gbps uplinks between switches in data center racks
 Server-to-switch connections over multimode fiber
 Aggregation or distribution links within campus and enterprise networks
 Patch-panel connections using multimode fiber (OM3/OM4)

How to use
Insert the SFP-10G-SR-RFB module into a compatible SFP+ port on a switch or router while the device is powered on; the transceiver is hot-swappable. Connect multimode duplex LC patch cords between transceivers on each end of the link, ensuring correct transmit/receive orientation. Verify link status and speed in the network device management interface and confirm that the connected ports are configured for 10 Gbps operation. If necessary, check fiber type and patch cord condition to maintain signal integrity.
Usage recommendations
Use OM3 or OM4 multimode fiber and quality LC duplex patch cords for reliable short-range performance. Ensure both ends of the link use compatible 10GBASE-SR modules and verify port settings in the switch or router. Keep connectors clean and protected, and follow ESD and handling precautions when installing or removing the module.
