Types of Huawei s Optical Modules
Huawei optical modules include SFP, SFP+, SFP28, XFP, QSFP+, QSFP28, CFP, and PON SFP modules, supporting a wide range of transmission rates from FE/GE to 100GE and specialized broadband access networks.
Standard Optical Modules
Huawei optical modules are classified by transmission rates and form factors to meet diverse networking requirements :
- SFP (Small Form-Factor Pluggable): Supports FE (Fast Ethernet) and GE (Gigabit Ethernet) with LC fiber connectors. Hot-swappable and widely used in standard networking.
- eSFP (Enhanced SFP): Similar to SFP but supports monitoring of voltage, temperature, bias current, transmit and receive optical power.
- SFP+ (Small Form-Factor Pluggable Plus): Supports 10GE transmission, compatible with LC connectors.
- SFP28: Same interface size as SFP+, supports 25GE transmission.
- XFP (10 Gigabit Small Form-Factor Pluggable): Provides 10 Gbit/s transmission, larger than SFP+ modules, supports LC connectors.
- QSFP+ (Quad SFP Plus): Supports 40GE transmission, uses MPO fiber connectors, larger than SFP+.
- QSFP28: Same interface as QSFP+, supports 100GE or 40GE transmission.
- CFP (Centum Form-Factor Pluggable): Large module (144.75 mm × 82 mm × 13.6 mm), used in data communication and telecom for high-speed networks.
PON Optical Modules
Huawei also offers PON SFP modules for broadband access networks, optimized for GPON, XG-PON, XGS-PON, and 50G-PON deployments :
- Transmission Rates: GPON (2.488 Gbps downstream / 1.244 Gbps upstream), XG-PON (9.953 Gbps downstream / 2.488 Gbps upstream), 50G-PON (up to 50 Gbps).
- Optical Classes: Class B+, C+, C+ Pro, and D, providing different optical budgets and supporting various distances (20–60 km) and splitter ratios.
- Connectors: SC optical connectors, single-mode fiber required.
- Compatibility: Designed for Huawei OLT platforms like MA5800 and MA5600T, with some combo modules supporting multiple PON standards simultaneously.
Key Features
- Hot-swappable: All modules can be replaced without powering down the device.
- Monitoring: eSFP modules allow real-time monitoring of operational parameters.
- Compatibility: Modules must match the interface type and transmission rate of the switch or OLT port.
- Applications: Used in enterprise networks, data centers, telecom networks, and FTTH deployments. Huawei's optical modules provide flexibility for high-speed data transmission, broadband access, and scalable network expansion, making them suitable for both enterprise and carrier-grade networks .
