Huijue Switch with 2 Optical Ports

The two optical ports on a Huawei switch serve as uplink ports for high-speed data transmission over fiber, supporting both pure optical connections and hybrid optical-electrical setups.

Function of the Optical Ports

The optical ports on Huawei switches are primarily uplink ports, designed to connect the switch to upstream devices such as aggregation switches, core switches, or remote units in a campus network . These ports enable high-speed, long-distance data transmission using optical fibers, which provide higher bandwidth and stronger anti-interference capabilities compared to traditional copper Ethernet ports .

Hybrid Optical-Electrical Capability

Huawei switches often support hybrid optical-electrical ports, which can operate in two modes:

1. Optical-Electrical Integration: The hybrid port uses a hybrid module and cable to transmit data and simultaneously receive PoE power. In this mode, the separate PoE_IN port is not required .
2. Optical-Electrical Separation: The hybrid port transmits data via a standard optical module, while the PoE_IN port receives power through a Phoenix connector. Both ports in the same group (PoE_IN0 or PoE_IN1) are used together . This flexibility allows the switch to support both fiber-based uplinks and remote PoE-powered devices without additional power infrastructure.

SFP Module Compatibility

The optical ports are typically SFP (Small Form-Factor Pluggable) slots, which accept various transceiver modules for different fiber types and distances, including multimode, single-mode, BiDi optics, and long-range modules up to 150 km . This modular design allows the switch to adapt to different network topologies and upgrade requirements without replacing the hardware.

Summary

In essence, the two optical ports on a Huawei switch:

• Act as uplink ports for connecting to higher-layer switches or remote units.
• Support high-speed fiber transmission for large bandwidth and long-distance connectivity.
• Can operate in hybrid optical-electrical mode to combine data and PoE power delivery.
• Accept SFP modules, providing flexibility for different fiber types and distances . These features make the optical ports essential for building scalable, high-performance campus or enterprise networks.
