Different versions of Huawei optical modules

Huawei optical modules are classified by transmission rate, form factor, fiber type, and wavelength, ranging from GE to 800GE modules for diverse networking needs.

Classification by Transmission Rate

Huawei optical modules support a wide range of transmission rates to meet different network requirements: FE (Fast Ethernet), GE (Gigabit Ethernet), 10GE, 25GE, 40GE, 100GE, and up to 800GE for high-performance data center networks . Higher transmission rates generally require more complex module structures.

Form Factor Types

Huawei modules come in various pluggable form factors to fit different devices:

• SFP (Small Form-Factor Pluggable): Supports LC fiber connectors, suitable for GE and FE applications .
• eSFP (Enhanced SFP): SFP with monitoring capabilities for voltage, temperature, bias current, and optical power .
• SFP+: High-speed SFP for 10GE, more sensitive to EMI, with tighter cages and additional springs .
• SFP28: Same interface as SFP+, supports 25GE or 10GE modules .
• XFP: 10GE module, larger than SFP+, supports LC connectors .
• QSFP+ (Quad SFP+): Supports MPO fiber connectors, used for 40GE .
• QSFP28: Same interface as QSFP+, supports 100GE or 40GE modules .
• CXP: High-density parallel optics transceiver, 12 channels per Tx/Rx, for short multimode links .
• QSFP-DD: High-speed pluggable module for data centers, supporting dense connections .
• CFP (Centum Form-Factor Pluggable): Large module for data communication and telecom, dimensions 144.75 mm × 82 mm × 13.6 mm .

Fiber Type and Distance

Optical modules are also classified by fiber type:

• Single-mode modules: Used with single-mode fibers for long-distance transmission, high bandwidth, and large capacity .
• Multimode modules: Used with multimode fibers for short-distance, lower-cost applications .

Wavelength Division Multiplexing

Huawei offers CWDM (Coarse WDM) and DWDM (Dense WDM) modules for long-distance and high-capacity transmission. DWDM modules are more efficient in wavelength utilization than CWDM .

Advanced Features for Data Centers

For AI and high-performance computing scenarios, Huawei provides modules with ultra-long transmission, high reliability, and enhanced security, supporting up to 800GE. These modules include features like channel loss resistance and contamination detection to improve reliability by 10x .

Summary

Huawei optical modules are highly versatile, supporting multiple transmission rates, form factors, fiber types, and wavelength standards. They are hot-swappable, compatible with S series devices, and designed for both telecom and data center applications, offering flexible plug-and-play options for modern network infrastructures .
