SFP-10G-LR Description
SFP-10G-LR is a Cisco 10GBASE-LR SFP+ optical transceiver for 10G Ethernet links over 1310 nm G.652 single-mode fiber. It is used to populate Cisco SFP+ host ports for longer single-mode fiber runs where the BOM calls for the standard LR 10 km cabling class, dual LC/PC connectors, commercial 0 to 70 degrees C operation, a blue bail latch, and 1W maximum power consumption; exact switch, router, or module support should be checked against Cisco transceiver compatibility documentation for the target platform and software release.

Application Scenarios
Select SFP-10G-LR for Cisco 10G SFP+ uplinks that need the LR 10 km class over a standard G.652 single-mode fiber plant.
Keep this PID separate from SFP-10G-LR-X and SFP-10G-LR10-I when stocking spares, because Cisco assigns those alternatives extended or industrial temperature scope and different multirate descriptions.
Attach the Cisco compatibility lookup to the bill of materials when the optic is ordered for Catalyst, Nexus, router, UCS, or MDS hardware. The data sheet lists broad platform families but also warns that not every listed device supports every module.

- In a SFP-10G-LR vs SFP-10G-LR-S comparison, both rows share the 10 km LR reach, 1310 nm SMF optical type, blue latch, and commercial temperature class; the table separates SFP-10G-LR-S as the S-Class order.
- The SFP-10G-LR difference from SFP-10G-LR-X is temperature and protocol scope, because SFP-10G-LR-X adds Cisco’s extended-temperature multirate LR/LW/OTU2e listing.
- SFP-10G-LR vs SFP-10G-LR10-I is an operating-environment comparison: SFP-10G-LR is commercial temperature, while SFP-10G-LR10-I is Cisco’s industrial-temperature LR and CPRI listing.
- For which model to choose, match the SKU to module class, temperature class, protocol scope, and the host-support result in Cisco compatibility documentation. SFP-10G-ER is included as an additional same-family comparison point.
Selection Guide
1. Choose it for standard Cisco 10 km LR links
Specify SFP-10G-LR when the fiber design calls for Cisco 10GBASE-LR over G.652 single-mode fiber and the required distance stays inside the documented 10 km class.
2. Keep S-Class orders separate
Use SFP-10G-LR-S only when the approved BOM names the S-Class LR PID rather than the standard SFP-10G-LR line.
3. Move to LR-X for extended temperature or multirate scope
Select SFP-10G-LR-X when Cisco’s extended-temperature LR/LW/OTU2e description is required by the host, service, or site condition.
4. Confirm platform support for purchasing
Verify the exact Cisco device, SFP+ port, and operating-system entry in Cisco compatibility documentation before releasing the optic for purchase.
Ordering Checklist
|
Check Item |
What to Confirm |
Procurement Risk Controlled |
|---|---|---|
|
Host support |
Cisco compatibility documentation covers the target platform, port, and software release |
Avoids approving the optic from form factor alone |
|
Fiber plant |
The circuit uses standard G.652 single-mode fiber for the 1310 nm LR path |
Keeps the 10 km reach tied to Cisco’s cabling table |
|
Connector plan |
Patch cords use LC/PC or LC/UPC connectors and avoid APC connectors |
Matches Cisco’s connector rule for this SFP+ family |
|
Minimum distance |
The link respects Cisco’s 2 m minimum cabling distance for LR modules |
Avoids back-to-back test connections outside the documented cabling note |
|
Temperature class |
The site fits commercial 0 to 70 degrees C operation |
Prevents using the standard LR line where LR-X or LR10-I is the supported environmental fit |
