Can Huawei S2300 use a 1550 optical module

The Huawei S2300 switch can only reliably use Huawei-certified optical modules, and using a 1550 nm module requires verification of certification.

Compatibility Overview

The Huawei S2300 series supports SFP optical modules for fiber connections, but not all optical modules are guaranteed to work. Huawei requires that switches use certified optical modules to ensure transmission reliability and service stability. Non-certified modules, even if they match the 1550 nm wavelength, may cause network issues and are not supported by Huawei .

Optical Module Types

1550 nm modules are typically used for long-distance single-mode fiber transmission. Huawei classifies optical modules by form factor and speed:

• SFP: Standard small form-factor pluggable modules, including 1000BASE-LX for 1550 nm single-mode fiber.
• SFP+ / XFP / SFP28: Higher-speed modules (10G or above), generally not supported on S2300, which is a 1G switch . The S2300 switch is designed for 10/100/1000 Mbps Ethernet ports with SFP uplinks, so it can support 1G SFP modules that operate at 1550 nm, provided they are Huawei-certified .

Certification Requirement

To ensure compatibility:

1. Check the module label for “HUAWEI”.
2. Use the display transceiver command on the switch; the Vendor Name should show HUAWEI.
3. Modules delivered after July 1, 2013, are generally eligible for certification verification . If the 1550 nm module is third-party or non-certified, Huawei does not guarantee functionality, and using it may result in link instability or hardware issues .

Recommendation

• Use Huawei-certified 1550 nm SFP modules for the S2300 switch.
• Avoid non-certified modules unless you are willing to accept potential network risks.
• Contact Huawei technical support to confirm whether a specific 1550 nm module is certified for the S2300 series. By following these guidelines, you can safely deploy 1550 nm optical modules on the S2300 switch while maintaining network reliability.
