Optical Module of Huawei Firewall

Fiber and communications infrastructure knowledge brief Published 21 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 firewalls support a range of optical modules including SFP, SFP+, SFP28, QSFP+, QSFP28, XFP, and CFP, depending on the model and required transmission speed.

Supported Optical Module Types

Huawei firewalls, particularly the USG series, are compatible with multiple optical module types to meet different network requirements: SFP (Small Form-Factor Pluggable): Standard modules for Gigabit Ethernet connections, suitable for short- to medium-distance links.eSFP: Enhanced SFP modules that support monitoring of voltage, temperature, bias current, transmit and receive optical power. SFP+: High-speed SFP modules for 10 Gbit/s transmission, commonly used in 10GE ports. SFP28: Supports 25 Gbit/s transmission, compatible with SFP+ interface size.

QSFP+ (Quad SFP Plus): Supports 40 Gbit/s transmission, typically using MPO fiber connectors. QSFP28: Supports 100 Gbit/s transmission or 40 Gbit/s when using QSFP+ modules, compatible with QSFP+ interface size.

XF

P: 10 Gbit/s modules with LC fiber connectors, larger than SFP+ modules.

CF

P (Centum Form-Factor Pluggable): High-speed modules for data communication and telecom applications, dimensions 144. 75 mm x 82 mm x 13. 6 mm.

Transmission Modes and Fiber Types

Huawei optical modules are designed for both single-mode fibers (SMF) and multi-mode fibers (MMF): Single-mode modules: Used for long-distance transmission with high bandwidth and large capacity. Multi-mode modules: Used for short-distance, lower-capacity links, offering cost-effective solutions. Modules are also classified by transmission rates: FE, GE, 10GE, 25GE, 40GE, and 100GE, allowing firewalls to support a wide range of network speeds.

Special Huawei Optical Modules

Huawei also offers the StarryLink optical module series, designed for ultra-long-distance, high-reliability, and secure transmission, particularly in data center and AI-driven network environments. These modules are optimized for high-bandwidth interconnections and low-latency enterprise networks.

Practical Considerations

All Huawei firewall optical modules are hot-swappable, allowing replacement without shutting down the device. Selection of the module depends on port type, required speed, and fiber type. For example, a USG6320 firewall with 10GE SFP+ ports will require SFP+ modules for 10 Gbit/s links.

For long-distance or high-capacity links, single-mode SFP, SFP+, or QSFP28 modules are recommended, while multi-mode modules are suitable for short-distance connections. In summary, Huawei firewalls are compatible with a wide range of optical modules, from standard SFPs for Gigabit Ethernet to high-speed QSFP28 and CFP modules for 100 Gbit/s links, supporting both single-mode and multi-mode fibers to meet diverse network deployment needs.
