SFP-10G-ER Description
SFP-10G-ER is a Cisco 10GBASE-ER SFP+ optical transceiver for 10 Gigabit Ethernet links over standard ITU-T G.652 single-mode fiber. It is used for long-reach fiber uplinks and BOM-matched host ports that require a Cisco SFP+ module with up to 40 km reach, 1550 nm wavelength operation, dual LC/PC connectivity, 1.5W maximum power consumption, and commercial 0 to 70 degrees C operation.

Application Scenarios
Use SFP-10G-ER when the bill of materials calls for a Cisco 10GBASE-ER SFP+ optic on standard G.652 single-mode fiber and the planned link reaches beyond the usual LR distance.
For 30 to 40 km fiber paths, keep the design tied to engineered-link review rather than treating the optic as a generic 40 km part. The cable loss value and host support record should travel with the quote.
Keep SFP-10G-ER separate from SFP-10G-ER-S and SFP-10G-ER-I in spares planning because the official ordering descriptions differ by S-Class positioning and industrial-temperature multirate support.

Ordering description |
10GBASE-ER SFP+ Module for SMF |
Multirate 10GBASE-ZR, 10GBASE-ZW and OTU2e SFP+ Module for SMF |
10GBASE-LR SFP+ Module for SMF |
- In a SFP-10G-ER vs SFP-10G-ER-S comparison, the table shows the same ER reach, SMF medium, wavelength, red latch, and commercial temperature class, while SFP-10G-ER-S is the S-Class ordering line.
- The SFP-10G-ER difference from SFP-10G-ER-I is temperature and protocol scope: SFP-10G-ER is the commercial 10GBASE-ER line, while SFP-10G-ER-I is the industrial-temperature multirate ER variant.
- SFP-10G-ER vs SFP-10G-ZR is a reach comparison; SFP-10G-ER is documented for up to 40 km, while SFP-10G-ZR is the longer Cisco ZR option at up to about 80 km.
- For which model to choose, match the fiber span, temperature class, transceiver family, and Cisco host-support entry before substituting another 1550 nm optic. SFP-10G-LR is included as an additional same-family comparison point.
Selection Guide
1. Choose it for 40 km ER reach
Select SFP-10G-ER when the design requires Cisco 10GBASE-ER over G.652 single-mode fiber and the planned distance fits the documented 40 km class.
2. Use LR for shorter 10 km runs
Move to the Cisco LR family when the link only needs the 10 km SMF class; ER adds attenuation and engineered-link checks that are not required for many shorter spans.
3. Use ER-I for industrial temperature needs
Choose SFP-10G-ER-I instead when the host and site require Cisco’s industrial-temperature multirate ER module rather than a commercial-temperature ER optic.
4. Review ZR only for longer spans
Evaluate SFP-10G-ZR when the fiber design needs Cisco’s longer 1550 nm ZR reach and the optical budget fits the ZR attenuation requirements.
Ordering Checklist
|
Check Item |
What to Confirm |
Procurement Risk Controlled |
|---|---|---|
|
Host support |
Cisco compatibility source confirms the platform, port, and software support |
Avoids approving the optic from SFP+ form factor alone |
|
Fiber plant |
Standard G.652 single-mode fiber is available for the 1550 nm ER span |
Keeps the reach claim tied to Cisco’s cabling table |
|
Connector plan |
Patch cords use LC/PC or LC/UPC ends, not APC ends |
Matches Cisco’s connector rule for this SFP+ family |
|
Minimum distance |
The link respects the 2 m minimum cabling distance for ER modules |
Avoids a lab or back-to-back connection outside Cisco’s cabling note |
|
Short-link attenuation |
Links under 20 km include 5 dB 1550 nm fixed-loss attenuation planning |
Reduces receiver overload risk during short ER deployments |
|
Engineered-link review |
Links beyond 30 km have documented cable loss and path characteristics |
Prevents treating the 40 km value as a plug-and-play span |
