SFP Module Cisco SFP-10G-LR-S= 10GBASE-LR

The Cisco SFP-10G-LR-S= is a 10GBASE-LR S-Class SFP+ transceiver designed for 10-Gigabit Ethernet links over single‑mode fibre. The hot‑swappable module fits into SFP+ ports on Cisco switches and provides optical interoperability with other 10GBASE interfaces such as XENPAK, X2 and XFP, making it suitable for data centre, enterprise and service provider environments. It is MSA‑compliant and covered by a 5‑year standard warranty.

Advantages

This SFP+ module supports a maximum data rate of 10,000 Mbit/s and offers hot‑swappable installation for minimal downtime. Its compact form factor (13.4 mm × 56.5 mm × 8.5 mm) saves rack space and simplifies deployment in high‑density systems. Optical interoperability with multiple 10GBASE form factors ensures flexible integration into existing networks.

Suitable for

• Data centre uplinks and interconnects
• Enterprise backbone and aggregation links
• Service provider metro and access networks

How to use

Power down the host device if recommended by the switch manufacturer, insert the hot‑swappable SFP+ module into an available SFP+ port until it seats firmly, and connect single‑mode fibre patch cords to the transmit and receive ports. After installation, verify link status on the switch and configure interface settings (speed, duplex, and any optical parameters) according to network requirements and the switch documentation.

Recommendations

Use single‑mode fibre for LR links and ensure transceiver optical specifications match the remote device. Observe ESD precautions during handling and follow Cisco or switch vendor guidelines for compatibility and firmware requirements.
