SFP-10G-SR Description
SFP-10G-SR is a Cisco 10GBASE-SR SFP+ transceiver for 10 Gigabit Ethernet short-reach links over 850 nm multimode fiber. It is used to match Cisco 10G SFP+ host ports to MMF cabling in switch, router, firewall, or module BOMs where the platform support matrix confirms compatibility. Cisco documents this SR optic with dual LC/PC connectors, a beige bail latch, up to 300 m reach on OM3 MMF, up to 400 m reach on OM4 or OM5 MMF, 1W maximum power consumption, and a commercial 0 to 70 degrees C operating temperature class.

Application Scenarios
Use SFP-10G-SR where Cisco-approved 10G SFP+ ports need an 850 nm SR optic across building closets, aggregation rooms, or rack areas already cabled with supported multimode fiber.
Keep this PID in the BOM when the link plan uses OM3 for up to 300 m or OM4/OM5 for up to 400 m. Do not substitute LR, LRM, ER, DAC, or AOC parts when the fiber run and optical budget are built for SR MMF.
Separate SFP-10G-SR from SFP-10G-SR-S, SFP-10G-SR-X, and SFP-10G-SR-I in spare pools. The suffix changes the S-Class, temperature, or multirate identity even when the connector, wavelength, and reach class look similar.

- In a SFP-10G-SR vs SFP-10G-SR-S comparison, both are Cisco 850 nm SR MMF optics with the same cabling table reach, while SFP-10G-SR-S is the S-Class entry and carries Cisco’s no-FCoE note.
- The SFP-10G-SR difference from SFP-10G-SR-X is temperature and protocol scope: SR is the commercial 10GBASE-SR listing, while SR-X adds extended-temperature multirate SR/SW/OTU2e positioning.
- SFP-10G-SR vs SFP-10G-SR-I is a commercial-versus-industrial comparison; SR-I adds Cisco’s industrial-temperature class and CPRI data-rate support.
- For which model to choose, match the PID to the required SR family position, temperature class, protocol scope, multimode cable grade, and Cisco host compatibility record. SFP-10G-LR is included as an additional same-family comparison point.
Selection Guide
1. Specify it for standard commercial SR links
Choose SFP-10G-SR when the BOM calls for Cisco’s standard 10GBASE-SR SFP+ optic over 850 nm multimode fiber.
2. Keep the cable grade tied to the reach target
Use OM3 only where the 300 m SR limit is enough. Use OM4 or OM5 when the documented SR link target is up to 400 m.
3. Move to X or I variants only for their documented role
Select SFP-10G-SR-X for the Cisco extended-temperature multirate SR listing, or SFP-10G-SR-I for Cisco’s industrial SR and CPRI-supported listing.
4. Verify the host before the quote is finalized
Confirm the Cisco platform, SFP+ port type, module slot, and operating-system support in Cisco compatibility documentation instead of approving the optic from form factor alone.
Ordering Checklist
|
Check Item |
What to Confirm |
Procurement Risk Controlled |
|---|---|---|
|
Host compatibility record |
Cisco compatibility documentation covers the target device, port, module, and operating system |
Avoids assuming support from the SFP+ shape alone |
|
Fiber class |
Link uses supported multimode fiber at the documented bandwidth and distance |
Keeps the design inside Cisco’s SR cabling table |
|
Connector type |
Patch cords use LC/PC or LC/UPC connectors rather than APC connectors |
Prevents connector mismatch during installation and test |
|
Port speed |
Target port is a Cisco-supported 10G SFP+ port for this optic |
Avoids installing a 10G optic into an unsupported SFP-only or unsupported host port |
|
Temperature class |
Site requirement fits Cisco’s commercial 0 to 70 degrees C class |
Prevents buying SR when the BOM actually needs SR-X or SR-I |
