Comparison of Huawei optical modules

Huawei optical modules vary by type, class, and performance, with higher-class GPON modules and higher-speed SFP/QSFP modules offering better transmission, lower fault rates, and higher cost.

GPON SFP Modules

Huawei GPON SF

P modules are widely used in FTTH and broadband access networks. The main classes are B+, C+, and C++, which differ in receiver sensitivity, optical port, and splitter ratio. Key points: B+: Entry-level, lower performance, higher fault rate, not recommended for critical deployments.

C+: Standard performance, commonly used in Huawei MA5600T and MA5800 OLT boards (GPBD, GPFD, GPUF, GPSF, GPHF), offering reliable operation and cost-effectiveness. C++: Highest performance, supports longer distances and higher split ratios, but comes at a higher price. Transmission rates for GPON modules are 2.

488 Gbps downstream and 1. 244 Gbps upstream, with distances up to 60 km. Some combo SFP+ modules support XG-PON, XGS-PON, and 50G-PON, enabling seamless migration to next-generation broadband.

SF

P, SFP+, SFP28, QSFP, and QSFP28 ModulesHuawei offers a range of pluggable optical modules for data centers and enterprise networks: SFP (Gigabit): Standard 1 Gbps, small form-factor, suitable for short to medium distances. SFP+ (10G): Higher rate, supports 10 Gbps, compatible with LC fiber connectors. SFP28 (25G): Same interface as SFP+, supports 25 Gbps for high-density data center applications.

QSFP+ (40G): Quad SFP, supports 40 Gbps, uses MPO connectors, larger form factor. QSFP28 (100G): Supports 100 Gbps, same interface as QSFP+, suitable for high-speed backbone links. QSFP-DD: Double density, up to 400 Gbps, power consumption around 12–14 W per module.

Modules differ in power consumption, connector type, and maximum transmission distance, with single-mode fibers supporting longer distances and multimode fibers optimized for short-range, high-bandwidth applications.

Value Considerations

Performance vs. Cost: Higher-class GPON modules (C++) and higher-speed SFP/QSFP modules provide better performance but at higher cost. B+ modules are cheaper but less reliable.

Deployment Suitability: Choose modules based on OLT compatibility, network scale, and future upgrade plans. For example, C+ modules are standard for Huawei OLTs, while C++ is used for high-demand scenarios.

Future-

Proofing: Combo SFP+ modules supporting multiple PON standards allow seamless migration to XG-PON, XGS-PON, and 50G-PON. Power and Thermal Management: QSFP-DD and high-speed modules require attention to power consumption and heat dissipation in dense deployments.
