Does the Huawei S79 series switch have an optical port

The Huawei S79 series switch supports optical connections via SFP or combo interfaces, allowing the use of certified optical modules.Optical Port Capability

Huawei S series switches, including the S79 series, typically support optical ports through SFP (Small Form-factor Pluggable) modules or combo interfaces, which combine a Gigabit Ethernet electrical interface and a Gigabit Ethernet optical interface on the same port . These interfaces cannot operate simultaneously; when one is active, the other is disabled. Users can configure the interface to work in fiber mode if an optical module is installed and the remote device is also using an optical interface .

Module Requirements

To ensure reliable transmission, Huawei requires that only certified optical modules be used with its switches. Certified modules are labeled with "HUAWEI" and meet the company's quality and compatibility standards . Non-certified modules may cause service instability and are not supported by Huawei.

Configuration and Monitoring

Once an optical module is installed, the switch can detect and display its status using commands such as display transceiver to view module type, wavelength, transfer distance, and vendor information . This allows network administrators to monitor optical port performance and ensure proper operation.

Summary

While the S79 series switch may not have fixed built-in optical ports, it supports optical connectivity through SFP or combo interfaces, provided that certified Huawei optical modules are used. This design allows flexible deployment in both copper and fiber networks, supporting high-speed data transmission and network scalability .
