1. Confirm the basic link conditions first.
Suitable for 10G metro aggregation, extended campus and long single-mode fiber links.
10G SFP+ Port
Confirm the host device supports standard 10G SFP+ interfaces.
Duplex LC SMF
Use OS2 single-mode fiber with duplex LC connectors.
Reach Up to 40km
Check fiber attenuation, connector loss and optical budget before deployment.
2. Know the module. Then check the project.
The 10GBASE-ER SFP+ transceiver is designed for extended 10G transmission over single-mode fiber. It is commonly used when LR reach is not enough and a 40km-class optical link is required.

Each module is qualified through optical parameter verification, BER testing and compatibility validation before shipment.
6. Not Sure Which 10G SFP+ Fits Your Link?
Different 10G SFP+ modules solve different deployment problems. Compare reach, fiber type and application before ordering.
| 10G Option | Typical Reach | Fiber / Connector | Best Fit | Check Before Ordering |
|---|---|---|---|---|
| 10GBASE-SR | 300m | OM3/OM4 MMF / Duplex LC | Data center short-reach links | Fiber type, distance and switch compatibility |
| 10GBASE-LRM | 220m | Legacy MMF / Duplex LC | Existing MMF upgrade | OM1/OM2 fiber condition and distance limit |
| 10GBASE-LR | 10km | OS2 SMF / Duplex LC | Campus interconnect | Host coding, link budget and fiber route |
| 10GBASE-ER | 40km | OS2 SMF / Duplex LC | Metro links beyond standard LR distance | Optical budget, fiber attenuation and connector cleanliness |
| 10GBASE-ZR | 80km | OS2 SMF / Duplex LC | Regional backbone / POP links | Optical budget, dispersion and attenuation requirement |
Frequently Asked Questions
i. When should I choose 10G ER instead of 10G LR?
Choose 10G ER when your link is longer than the typical 10km LR range and needs a 40km-class single-mode fiber solution. For standard campus links within 10km, 10G LR is usually more cost-effective.
ii. What should I check before deploying a 40km 10G ER link?
Check fiber distance, total link loss, connector cleanliness, patch panels and the optical budget. Long-distance links are more sensitive to fiber attenuation and dirty connectors than short campus links.
iii. Can this 10G ER module work with my existing switch?
Yes. The module can be programmed for Cisco, Juniper, Arista, HPE and other vendor environments. Please share the switch model or required compatibility code before shipment.
iv. Why does a long-distance 10G ER link fail even when both modules are good?
Common causes include excessive fiber loss, dirty LC connectors, poor splicing, incorrect compatibility coding or an optical power level outside the receiver range. The full link environment should be checked before replacing modules.
v. What information should I provide before ordering?
Please confirm your switch brand and model, required compatibility, link distance, fiber type, patch panel condition and operating temperature. Axonode can help verify the correct module before shipment.
