Huawei Optical Module Common Models
Optical modules are important devices in fiber optic communication systems. Huawei Optical Module is manufactured by Huawei
15 Huawei optical modules
Huawei optical modules are pluggable transceivers used for converting electrical signals to optical signals, supporting various transmission rates, fiber types, and distances.
Types and Form Factors
Huawei offers a wide range of optical modules to meet different network requirements :
- SFP (Small Form-factor Pluggable): Supports 100M to 1G transmission, typically with LC connectors for short- to medium-distance links.
- eSFP (Enhanced SFP): Similar to SFP but with monitoring capabilities for voltage, temperature, bias current, and optical power.
- SFP+: Supports 10G transmission, compatible with LC connectors.
- XFP: 10G modules, larger than SFP+, also using LC connectors.
- SFP28: Supports 25G transmission, same interface size as SFP+.
- QSFP+ and QSFP28: Quad small form-factor pluggable modules for 40G and 100G transmission, using MPO connectors.
- CFP: Centum form-factor pluggable modules for high-speed data communication, dimensions 144.75 mm x 82 mm x 13.6 mm.
Transmission Rates and Fiber Types
Huawei optical modules cover a broad range of transmission rates :
- FE (Fast Ethernet): 100M
- GE (Gigabit Ethernet): 1G
- 10GE, 25GE, 40GE, 100GE: Higher-speed modules for data centers and backbone networks Modules are available for single-mode fibers (long-distance, high-capacity) and multi-mode fibers (short-distance, cost-effective) with wavelengths typically at 850 nm, 1310 nm, or 1550 nm. Wavelength division multiplexing (CWDM and DWDM) modules allow multiple wavelengths on a single fiber for increased capacity.
Common Models
Some widely used Huawei optical modules include :
- SFP-FE-SX-MM1310: Multi-mode, 100M/155M, 2 km, LC connector
- eSFP-FE-LX-SM1310: Single-mode, 100M/155M, 15 km, LC connector
- S-SFP-FE-LH40-SM1310: Single-mode, 100M/155M, 40 km, LC connector
- S-SFP-FE-LH80-SM1550: Single-mode, 100M/155M, 80 km, LC connector
- GPON-OLT-CLASS-C+/C++: For GPON access networks, SC fiber interface
Applications
Huawei optical modules are used in:
- Data centers: High-speed interconnects and server-to-switch links
- Telecommunication networks: Long-distance backbone and metro networks
- GPON networks: Fiber-to-the-home (FTTH) access
- Enterprise networks: Flexible plug-and-play solutions for various interface requirements
Additional Considerations
- Hot-swappable: All modules can be replaced without powering down the device.
- Monitoring: eSFP modules provide real-time monitoring of optical parameters.
- Power consumption: QSFP DD modules typically consume 12–14 watts per module; exact values depend on the model .
- Distance and wavelength selection: Choose modules based on fiber type, required distance, and network speed. Huawei's portfolio of optical modules ensures compatibility with a wide range of devices and network scenarios, providing flexibility for both short- and long-distance optical communication deployments.
