SFP Transceiver Module Cisco SFP-10G-SR-S=-RFB 10GBASE-SR 850nm

Cisco SFP-10G-SR-S=-RFB is a hot-pluggable SFP+ transceiver module designed for 10GBASE-SR operation at an 850 nm wavelength. It is intended for short-range multimode fibre links and provides 10 Gigabit Ethernet connectivity for compatible SFP+ ports. The module is typically used in data center aggregation, server uplinks and other short-distance fibre channel applications where a standard 10GBASE-SR interface is required. The product name, brand and manufacturer part number are Cisco SFP-10G-SR-S=-RFB.

Advantages

The module supports hot-pluggable installation, enabling replacement or addition without powering down the host device. It is optimized for 10GBASE-SR multimode fibre links at 850 nm and is compatible with SFP+ form-factor slots that accept Cisco modules. The compact SFP+ design conserves port density in switches and servers and simplifies deployment in short-range fiber networks.

Suitable for

• Data center aggregation links
• Server uplinks to top-of-rack or spine switches
• Short-range multimode fibre connections (10GBASE-SR)
• Environments using SFP+ ports compatible with Cisco modules

How to use

Install the transceiver into a compatible SFP+ port on the powered host device by aligning the module with the slot and pressing until it latches. Connect an appropriate multimode fibre patch cord (matched to 850 nm operation) between transceivers at both ends of the link, ensuring correct transmit/receive orientation. Verify link status on the host device and configure the interface as required by the network operating system. For removal, depress the module latch and pull the transceiver straight out while the device remains powered if hot-swap capability is needed.

Recommendations

Use multimode fibre (MMF) cabling that meets the required OM classification for 10GBASE-SR at the intended link distance, maintain clean connector end-faces, and confirm host compatibility with Cisco SFP+ modules. Avoid exposing the transceiver to excessive dust or moisture when not installed and follow the host vendor’s guidelines for hot-plug operation.
