SFP-10G-SR-X Description
SFP-10G-SR-X is the Cisco extended-temperature 10GBASE-SR SFP+ transceiver for short-reach 10 Gigabit Ethernet and optical transport links over 850 nm multimode fiber. It is a multirate SR optic for 10GBASE-SR, 10GBASE-SW, and OTU2/OTU2e service designs, using a dual LC/PC connector with documented reach up to 300 m on OM3 MMF and up to 400 m on OM4 or OM5 MMF. The -X temperature class supports deployments that need a Cisco SFP+ SR module rated from -5 to 85 degrees C, with 1W maximum power consumption and host support that must be checked against Cisco transceiver compatibility documentation.

Application Scenarios
Specify SFP-10G-SR-X where a Cisco-approved 10G SFP+ port needs an 850 nm SR optic and the environment requires Cisco’s EXT temperature class instead of the commercial SR listing.
Keep this PID in the BOM when the service plan calls for Cisco’s SR, SW, or OTU2/OTU2e multirate description over supported multimode fiber.
Store SFP-10G-SR-X separately from SR, SR-S, and SR-I optics. The shared beige latch, 850 nm wavelength, and MMF reach do not remove the ordering difference created by temperature class and protocol scope.

- In a SFP-10G-SR-X vs SFP-10G-SR comparison, both are Cisco 850 nm SR MMF optics with the same cabling table reach, while SFP-10G-SR-X adds extended-temperature and multirate SR/SW/OTU2e positioning.
- The SFP-10G-SR-X difference from SFP-10G-SR-S is module role: SR-X is the EXT multirate line, while SR-S is the commercial S-Class line with Cisco’s no-FCoE note.
- SFP-10G-SR-X vs SFP-10G-SR-I is a temperature-class comparison; SR-X is Cisco’s extended-temperature SR optic, while SR-I is the industrial-temperature SR option with CPRI data-rate support.
- For which model to choose, align the order with the required temperature class, protocol scope, multimode reach, and Cisco host-compatibility result.
Selection Guide
1. Match the X suffix to the environment
Choose SFP-10G-SR-X only when the BOM calls for Cisco’s extended-temperature SR PID rather than the standard commercial SR or S-Class SR line.
2. Keep the fiber plan inside the SR table
Approve the link when the route uses supported multimode fiber and stays within the documented 300 m OM3 or 400 m OM4/OM5 reach.
3. Check the protocol requirement
Use this SKU for Cisco’s SR, SW, or OTU2/OTU2e multirate description; keep SR or SR-S orders separate when the requirement is only the commercial Ethernet SR listing.
4. Verify the host record before purchasing
Confirm the exact Cisco platform, SFP+ port, module bay, port mode, and software release in Cisco compatibility documentation or the applicable Cisco hardware guide.
Ordering Checklist
|
Check Item |
What to Confirm |
Procurement Risk Controlled |
|---|---|---|
|
Receiving label |
The device label and purchase paperwork carry SFP-10G-SR-X without dropping the X suffix |
Blocks accidental fulfillment with commercial SR, S-Class SR, industrial SR, LRM, LR, DAC, or AOC items |
|
EXT site requirement |
The installation target needs the -5 to 85 degrees C Cisco extended-temperature class |
Prevents a standard commercial-temperature SR optic from filling an environmental requirement |
|
Service mode |
The link plan is for SR short reach and may require Cisco’s SR/SW/OTU2e multirate description |
Keeps SR-X tied to its documented protocol scope instead of a generic 10G SR request |
|
Host and bay evidence |
The target Cisco device, SFP+ bay or port, port mode, and software release are covered by official support documentation |
Reduces the risk of approving the part only because the connector is physically SFP+ |
|
Multimode path |
The fiber plant is MMF and the run fits the Cisco SR limits for OM3, OM4, or OM5 |
Prevents a short-reach optic from being assigned to an unsupported fiber grade or distance |
|
LC patching |
Patch cords are LC/PC or LC/UPC and installation teams exclude APC-ended jumpers |
Avoids optical test failures caused by connector-polish mismatch |
