Huawei switches support 100Mbps optical ports

Fibre interconnection and data room reference Published 22 Apr 2026

Use this reference to prepare product questions for FD SOLUCIONES. Check interfaces, capacity, protection and installation requirements against the current product documentation.

Yes, Huawei switches support 100Mbps optical ports using certified 100M SFP modules. 100M Optical Module SupportHuawei switches, particularly the S Series and CloudEngine S5732-H series, can support 100Mbps optical ports through certified SFP modules such as the SFP-FE-SX-MM1310 (part number: 02315233),. These modules are designed for reliable transmission and must be Huawei-certified to ensure service stability.

Non-certified modules may cause connectivity issues and are not supported by Huawei.

Hybrid and Auto-

Sensing Ports

Many Huawei switches, including the CloudEngine S5732-H series, feature hybrid optical and electrical ports that support 100M/1G/2. 5G/5G/10G auto-sensing. This allows a single port to automatically detect and operate at the appropriate speed depending on the connected device, whether it is a 100M access switch, Wi-Fi 6 AP, or other network terminal.

This flexibility simplifies deployment and future upgrades without requiring new cabling.

Upgrade and Compatibility

For switches with hybrid ports, the uplink optical ports can support 1G/10G/25G/40G/100G, and the bandwidth can be upgraded by replacing the optical module if higher speeds are needed in the future. This ensures that 100M optical connections are fully compatible while allowing seamless upgrades to higher speeds as network demands increase.

Certification and Reliability

Huawei emphasizes using certified optical modules for all switch models. Certified modules are labeled with "HUAWEI" and verified through commands such as display transceiver or display elabel. Using certified 100M optical modules ensures stable performance and avoids potential service disruptions.

Summary

Huawei switches do support 100Mbps optical ports with certified SFP modules. Hybrid ports on models like CloudEngine S5732-H can auto-sense speeds from 100M to 10G. Certified modules are required for reliable operation and network stability.

Future upgrades to higher speeds are possible by replacing optical modules without recabling. This makes Huawei switches suitable for mixed-speed environments, including legacy 100M devices and modern high-speed access points.
