Optical module SFP Huawei

Huawei SFP optical modules are certified pluggable transceivers designed for reliable data transmission in Huawei S series switches, available in various types and speeds including SFP, SFP+, SFP28, and XFP.

Overview

Huawei SFP (Small Form-factor Pluggable) modules are hot-swappable optical transceivers used to connect switches to fiber optic networks. They support different data rates, fiber types, and transmission distances, making them suitable for enterprise, data center, and carrier networks . Common types include:

• SFP: Standard 1G modules for short- or long-distance connections.
• SFP+: Enhanced SFP supporting 10G transmission, e.g., Huawei SFP-10G-LR for 10 km single-mode fiber at 1310 nm .
• SFP28: Supports 25G transmission with the same form factor as SFP+.
• XFP: 10G modules, larger than SFP+, typically used in high-speed backbone links.

Certification and Compatibility

Huawei requires that only certified optical modules be used with its switches to ensure transmission reliability and service stability . Certified modules are labeled with "HUAWEI" and can be verified using commands such as display elabel, display version, or display transceiver. Modules delivered after January 1, 2016, should have:

• Manufactured date later than 2016-01-01
• Version V200R008 or later
• Vendor Name field displaying HUAWEI Non-certified modules may cause frequent link up/down issues or reduced performance, and Huawei does not provide support for problems caused by non-certified modules .

Key Specifications

• Transmission distance: Varies by module type and fiber; e.g., SFP-10G-LR supports up to 10 km over single-mode fiber .
• Wavelength: Typically 850 nm for multimode, 1310 nm or 1550 nm for single-mode.
• Connector type: LC fiber connectors are standard.
• Operating temperature: Usually 0°C to 70°C for standard modules.
• Transmit/receive power: Modules have defined ranges to ensure signal integrity, e.g., -8.2 to +0.5 dBm transmit power for SFP-10G-LR .

Advanced Features

• eSFP modules: Support monitoring of voltage, temperature, bias current, transmit and receive optical power.
• Plug/unplug verification: Certified modules undergo comprehensive testing for signal quality, error tolerance, EMC, and environmental parameters .

Purchasing and Datasheets

Huawei SFP modules are available globally, both new and refurbished, with datasheets downloadable for detailed specifications . When selecting a module, ensure it matches the switch port type, required data rate, fiber type, and distance.

Summary

Huawei SFP optical modules provide reliable, certified connectivity for S series switches. Choosing the correct type (SFP, SFP+, SFP28, XFP) and verifying certification ensures stable network performance, compliance with Huawei standards, and long-term operational reliability .
