Optical transceiver module Cisco 10GBASE-SR SFP 10 Gbps for multimode fiber

Cisco 10GBASE-SR SFP optical transceiver is a hot-pluggable small form-factor pluggable module that supports 10 Gbps data transmission over multimode fiber. Intended for short-range Ethernet and data center interconnects, the module fits SFP+ ports on compatible switches, servers and storage devices to enable high-bandwidth links for aggregation, access and server-to-server connectivity.

Advantages

The transceiver delivers reliable 10 Gbps performance for short-range multimode fiber links while offering hot-swappable installation and broad interoperability with Cisco SFP+ compatible equipment. Its compact SFP form factor saves space in dense networking environments and simplifies upgrades from lower-speed modules. The module follows industry optical specifications for predictable link budgets and supports standard Ethernet and Fibre Channel over multimode fiber.

Suitable for

• Short-range 10 Gigabit Ethernet links in data centers and enterprise networks
• Server-to-switch and switch-to-switch uplinks over multimode fiber
• Top-of-rack aggregation and access layer connectivity
• High-bandwidth storage area network (SAN) connections over multimode fiber

Key specifications

• Data rate: 10 Gbps
• Interface: SFP+ small form-factor pluggable
• Optical type: 10GBASE-SR for multimode fiber
• Reach: short-range links over multimode fiber (typical distances depend on fiber type and transceiver pairing)
• Wavelength: multimode-optimized laser (850 nm nominal)
• Hot-swappable: yes

How to use

Install the transceiver into an empty SFP+ port on a compatible switch, server NIC or storage device while the host is powered on or according to the device manufacturer’s hot-swap guidance. Connect the multimode fiber patch cable to the transceiver’s optical interface, ensuring the correct connector type and cleanliness of fiber end faces. Verify link status and speed through the host device management interface or diagnostics and monitor link LEDs to confirm an active 10 Gbps connection. Follow your network equipment vendor’s instructions for compatibility checks and firmware requirements.

Recommendations

Use multimode fiber of the appropriate grade (OM3/OM4) for expected reach and throughput, keep optical connectors clean, and verify compatibility with your network device model and firmware version. For predictable performance in data center environments, test the link after installation and maintain an inventory of spare modules for rapid replacement.
