Yes, Huawei switches with optical ports can be connected to a fully optical network, provided compatible optical modules and fiber types are used.

Compatibility and Requirements

Huawei all-optical switches, such as the CloudEngine S5732-H-V2 and S5700/S5720 series, are designed to function in fully optical networks, supporting both optical uplink and downlink ports for high-speed fiber connections . These switches can serve as core, aggregation, or access devices in campus or metropolitan networks, enabling fiber-to-the-room deployment and high-bandwidth transmission up to 100GE or more .

Optical Modules

To ensure reliable connectivity, Huawei switches must use Huawei-certified optical modules. Non-certified modules may cause transmission errors, service instability, or alarms, and Huawei does not guarantee support for third-party modules . Modules must match the switch port type and speed; for example, a 10G module cannot be used on a 1G interface .

Fiber Type and Wavelength

Compatibility between fiber and optical modules is critical. Single-mode fibers must be paired with single-mode modules, and multimode fibers with multimode modules. Mixing fiber types or using incorrect wavelengths can prevent the link from establishing . Monitoring tools and commands, such as display transceiver interface <interface> on Huawei switches, can verify optical power, wavelength, and link status .

Network Integration

Huawei optical switches can be seamlessly integrated into a fully optical network. They support:

• High-speed uplinks and downlinks for core-to-access connectivity.
• Plug-and-play remote units (RUs) for simplified deployment and centralized management .
• Hybrid or fully optical topologies, including ring or chain stacking for multiple switches .
• Advanced features like VXLAN, security probes, and flexible packet processing for scalable optical networks .

Best Practices

1. Use certified Huawei optical modules to ensure interoperability and stability.
2. Match fiber type and module specifications (single-mode vs. multimode, correct wavelength, and speed).
3. Verify link status and optical power using switch commands before deployment.
4. Plan network topology according to switch capabilities, using uplink ports for aggregation and downlink ports for access connections. By following these guidelines, Huawei switches with optical ports can reliably operate in a fully optical network, providing high-speed, low-latency, and scalable connectivity.
