The optical module cannot be installed in an optical interface because the optical module structure is non-standard. The structure
Huawei optical module optical to electrical port
Huawei optical-to-electrical modules allow a single interface to operate in either optical or electrical mode, supporting flexible connectivity for GE and 10GE ports.
Module Types and Specifications
Huawei offers several types of optical/electrical modules:
- 100 Mbit/s eSFP modules: Used on GE optical ports of Combo ports, with a wavelength of 1310 nm and a transmission distance up to 15 km .
- 1 Gbit/s SFP/eSFP modules: Compatible with GE interfaces for interconnection between optical and electrical ports. Wavelengths include 850 nm, 1310 nm, or 1550 nm, with distances from 0.5 km to 100 km .
- 10 Gbit/s SFP+ modules: Designed for 10 GE optical ports, supporting wavelengths of 850 nm, 1310 nm, or 1550 nm, with transmission distances up to 80 km .
- Hybrid optical-electrical modules: These modules allow simultaneous data transmission via optical fiber and PoE power delivery via electrical connections when used with second-generation hybrid cables . Modules are classified by single-mode or multimode fibers, with single-mode supporting long-distance transmission and multimode suitable for short-distance, cost-effective connections .
Combo Interface Operation
Huawei Combo interfaces consist of one optical and one electrical port sharing a single forwarding interface. Only one port can be active at a time:
- Default state: Electrical interface active.
- Switching to optical: Use the command
combo enable fiberin interface mode. - Switching back to electrical: Use
undo combo enable fiber. After switching, the corresponding SFP module can operate normally. Ensure the same configuration is applied on the peer device to maintain connectivity .
Configuration and Troubleshooting
- Verify fiber and module compatibility (single-mode vs multimode) to avoid connection issues .
- Avoid using modules with a higher rate than the interface (e.g., 10G module on a 1G port), .
- Check port status using commands like
display interface xgigabitethernet0/0/2anddisplay transceiver interface xgigabitethernet 0/0/2 verboseto monitor optical power, wavelength, and module health . - For hybrid setups, second-generation hybrid cables simplify connections by combining optical data and PoE power in a single port, reducing cabling complexity .
Practical Use Cases
- Direct connection: Connect a hybrid cable from a switch's hybrid optical-electrical port to an AP or remote unit.
- HDF-based connection: Use hybrid cables to connect through Huawei Distributed Fiber (HDF) units for extended network deployments . Huawei optical-to-electrical modules provide flexible, high-speed connectivity for enterprise networks, supporting both optical and electrical interfaces while ensuring compatibility with hybrid cabling solutions. Proper configuration and module selection are essential for optimal performance and reliability.
