What optical module does Huawei use

Fiber and communications infrastructure knowledge brief Published 26 Aug 2025

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

Huawei uses a wide range of optical modules, including SFP, SFP+, SFP28, XFP, QSFP+, QSFP28, CFP, and high-speed 400G/800G modules powered by self-developed photonic chips.

Common Optical Module Types

Huawei offers multiple pluggable optical module form factors for different network needs: SFP (Small Form-factor Pluggable): Standard gigabit modules for short- and long-distance transmission. SFP+: Enhanced SFP supporting 10 Gbit/s transmission. SFP28: Supports 25 Gbit/s, compatible with SFP+ interfaces.

XF

P: 10 Gbit/s modules with LC fiber connectors, larger than SFP+. QSFP+: Quad small form-factor pluggable supporting 40 Gbit/s, using MPO fiber connectors. QSFP28: Supports 100 Gbit/s or 40 Gbit/s, compatible with QSFP+ interfaces.

CF

P (Centum Form-factor Pluggable): Larger modules for high-capacity data communication and telecom applications. QSFP-DD (Double Density): High-density modules for 400G networks, with power consumption around 12–14 watts per module.

Advanced High-

Speed Modules

For AI and data center scenarios, Huawei provides modules ranging from GE to 800GE, emphasizing three capabilities: Spanning (ultra-long transmission), Stable (high reliability), and Secure (enhanced security). These modules support high-bandwidth, low-latency connections and are designed for resilient data center interconnectivity. Photonic Chip TechnologyHuawei's optical modules leverage self-developed photonic chips, including:oDSP (Optical Digital Signal Processing) chips in the OptiXtreme series, supporting adjustable single-wavelength rates from 100G to 600G, with spectrum efficiency up to 8 bit/s/Hz.

Thin Film Lithium Niobate (TFLN) modulators, increasing bandwidth by 50% and reducing power consumption by 30% compared to traditional indium phosphide modulators. Modules for 400G/800G transmission integrate silicon photonic chips for optical-electrical integration, reducing power consumption by 30% and extending transmission distances.

Fiber and Wavelength Options

Huawei optical modules are available for single-mode and multimode fibers: Single-mode modules: Support long-distance, high-capacity transmission. Multimode modules: Lower cost, suitable for short-distance, small-capacity applications. Modules also support wavelength division multiplexing (WDM): CWDM (Coarse WDM) and DWDM (Dense WDM) allow multiple wavelengths on a single fiber, improving efficiency and reducing fiber usage.

SummaryHuawei's optical modules cover a broad spectrum of form factors, transmission rates, and fiber types, from standard SFPs to high-speed 800G modules with advanced photonic chips. They are designed for data centers, AI clusters, and telecom networks, offering high reliability, long-distance transmission, and flexible plug-and-play deployment options.
