Huawei optical module gigabit SFP

Specialty cable knowledge brief Published 31 Aug 2023

Prepared for preliminary research by the ZITHA SPECIALTY knowledge desk. Confirm fire performance, mechanical protection, loss budgets and installation requirements against current standards and product documentation.

Yes, Huawei SFP ports can use gigabit optical modules, provided the modules are certified or compatible with the switch.Fiber Optical Modules

Huawei offers gigabit SFP fiber modules such as the eSFP-GE-SX-MM850, which supports 1.25 Gbps transmission over multimode fiber with LC duplex interfaces and distances up to 550 meters on OM2 fiber . These modules comply with SFP MSA and IEEE 802.3z standards, support digital diagnostics (DDM/DOM), and are hot-swappable, making them suitable for 1000BASE-SX networks and compatible with Huawei S5700 and S5720 series switches .

Copper SFP Modules

For copper connections, Huawei provides 10/100/1000BASE-T SFP transceivers that support 1 Gbps over Cat5e/6 cables up to 100 meters. These modules comply with IEEE 802.3ab standards and include standard SFP MSA serial ID information for proper recognition by Huawei switches .

Certification and Compatibility

Huawei emphasizes that only certified optical or copper modules should be used to ensure transmission reliability and service stability. Non-certified modules may cause link failures or unsupported transceiver alarms . Certified modules are typically labeled with "HUAWEI" and recognized by the switch via commands such as display transceiver or display version .

Practical Considerations
  • SFP ports are backward compatible with 1G modules, so a 1G SFP can be used in a port that supports higher speeds (e.g., SFP+), but the link will operate at 1 Gbps .
  • Ensure the module type matches the fiber type (single-mode vs multimode) and distance requirements.
  • Using Huawei-certified modules simplifies support and avoids EEPROM or software compatibility issues . In summary, Huawei SFP ports can use gigabit optical modules, both fiber and copper, as long as the modules are certified or compatible with the switch model and meet the required standards for speed, fiber type, and distance.
