SFP modul Cisco SFP-10G-SR-S-RFB 10GBASE-SR krátkovzdialené multimódové optické vlákno

Cisco SFP-10G-SR-S-RFB is a 10GBASE-SR small form-factor pluggable (SFP+) optical transceiver designed for short-range multimode fiber links. Intended for 10 Gbps Ethernet applications, this hot-pluggable module supports high-speed uplinks, server interconnects and switch stacking in data centers and enterprise networks. The module is compatible with standard SFP+ ports that accept Cisco SFP-10G-SR-S-RFB and works with multimode fiber (MMF) for typical short-distance connections.

Advantages

The Cisco SFP-10G-SR-S-RFB provides a compact pluggable form factor, enabling easy installation and replacement without powering down equipment. It supports 10 Gbps Ethernet transmission over multimode fiber, offering low-latency, high-bandwidth connectivity for short-range links. The transceiver complies with SFP+ specifications and is engineered for interoperability with Cisco networking equipment and many third-party systems that accept Cisco-certified modules.

Suitable for

• 10 Gigabit Ethernet uplinks between switches and routers
• Server-to-switch and server-to-server connections in data centers
• Switch stacking and short-reach interconnects within enterprise networks
• Multimode fiber links using OM3/OM4 cabling for distances typically up to several hundred meters

How to use

Ensure the network device supports SFP+ modules and is compatible with the Cisco SFP-10G-SR-S-RFB. Power down the port if recommended by the equipment vendor, insert the SFP+ transceiver into the SFP+ slot until it latches, and connect the multimode fiber cable (observe correct LC connector orientation). After insertion, verify link status and speed on the host device. Follow vendor firmware and configuration guidelines to enable 10 Gbps operation and any link diagnostics or monitoring features.

Recommendations

Use OM3 or OM4 multimode fiber for optimal reach and performance with the Cisco SFP-10G-SR-S-RFB. Keep fiber connectors clean and use dust caps when the transceiver is not in use. Check compatibility notes for the host device and update device firmware where required to ensure full functionality and accurate diagnostics.
