SFP-10G-ER-I Description
SFP-10G-ER-I is a Cisco industrial-temperature 10GBASE-ER SFP+ transceiver for 10G Ethernet and OTN optical links over G.652 single-mode fiber. It supports 10GBASE-ER, 10GBASE-EW, and OTU2/2e operation, uses 1550 nm optics with dual LC/PC connectors, and is specified for up to 40 km reach. Cisco lists the module with a 1.5W maximum power draw and an industrial -40 to 85 degrees C operating temperature range, while exact host platform and software support remain governed by Cisco transceiver compatibility documentation.

Application Scenarios
Use SFP-10G-ER-I when the bill of materials needs a Cisco ER-class SFP+ optic and the installation temperature profile requires the industrial range instead of a commercial-temperature ER module.
For carrier Ethernet or OTN-facing designs, SFP-10G-ER-I is the ER family member Cisco documents with 10GBASE-EW and OTU2/2e support, so the protocol requirement should be checked before substituting SFP-10G-ER or SFP-10G-ER-S.
Keep SFP-10G-ER-I as a separate spare from ER commercial, ER S-Class, and ZR industrial optics. The spare bin should reflect reach class, temperature class, and host-support records rather than grouping all 1550 nm SFP+ optics together.

10GBASE-ER SFP+ Module for SMF |

- In a SFP-10G-ER-I vs SFP-10G-ER comparison, the table keeps the ER 40 km SMF reach and red latch aligned, while SFP-10G-ER-I adds industrial temperature and multirate ER/EW/OTU2e scope.
- The SFP-10G-ER-I difference from SFP-10G-ER-S is not reach; both are ER-class 1550 nm optics, but SFP-10G-ER-S is the S-Class commercial-temperature line while SFP-10G-ER-I is the industrial multirate order.
- SFP-10G-ER-I vs SFP-10G-ZR-I is a reach and optic-family comparison: SFP-10G-ER-I is the 40 km ER part, while SFP-10G-ZR-I is the industrial ZR part documented for a longer reach class.
- For which model to choose, match the reach class, temperature class, protocol scope, and Cisco host-support entry before replacing one 1550 nm SFP+ SKU with another.
Selection Guide
1. Choose it for industrial ER links
Select SFP-10G-ER-I when the deployment needs Cisco 10GBASE-ER over G.652 SMF and the operating-temperature requirement is industrial rather than commercial.
2. Keep commercial ER separate
Use SFP-10G-ER when the same 40 km ER reach is required but the site does not need the industrial temperature rating or multirate ER/EW/OTU2e order line.
3. Do not replace it with S-Class by reach alone
Use SFP-10G-ER-S only where the Cisco S-Class ER SKU is the intended order; the S-Class label and commercial temperature class are different purchase facts from SFP-10G-ER-I.
4. Move to ZR-I only for the longer ZR class
Evaluate SFP-10G-ZR-I when the design calls for Cisco’s industrial ZR optic family and the fiber budget fits the longer ZR reach class instead of ER.
Ordering Checklist
|
Check Item |
What to Confirm |
Procurement Risk Controlled |
|---|---|---|
|
Industrial order code |
Sales order and receiving label use SFP-10G-ER-I |
Keeps the industrial ER optic from being replaced by ER commercial, ER S-Class, LR, or ZR parts |
|
Cisco host record |
The target platform, port, and operating system appear in Cisco compatibility documentation |
Prevents approval based only on SFP+ form factor and 40 km reach |
|
Site temperature envelope |
The installation requires the Cisco industrial -40 to 85 degrees C class |
Avoids purchasing a commercial-temperature ER module for an industrial location |
|
Service protocol scope |
The BOM calls for 10GBASE-ER, 10GBASE-EW, or OTU2/2e support |
Protects transport-service designs that depend on the multirate ER-I order line |
|
SMF path budget |
The span uses G.652 single-mode fiber and has documented loss for the 1550 nm ER link |
Keeps 40 km planning tied to measured fiber conditions and engineered-link review beyond 30 km |
|
Patch and attenuation bill |
LC/PC or LC/UPC patch cords are specified, with 5 dB 1550 nm fixed-loss attenuation for links under 20 km |
Avoids connector mismatch and short-span receiver overload risk |
