Is the hybrid energy optical cable of the communication base station grounded

How does a hybrid cable work?

This is where the hybrid cable comes in. It transmits data signals via optical fibers and transmits electrical signals via copper wires, enabling long-distance power supply without deteriorating the data transmission speed.

What is a hybrid cable?

Hybrid cable is a key component in Huawei's All-Optical Campus Network Solution. The following figure shows its appearance. The question is why hybrid cables can support long-term bandwidth evolution and long-distance PoE power supply, while twisted pairs or optical fibers cannot. Appearance of the hybrid cable The answer falls into two parts:

What is a fiber optic & copper hybrid cable?

Fiber Optic and Copper Hybrid Cable: This type of hybrid cable combines optical fibers for high-speed data transmission with copper conductors for power delivery or low-speed communication. It is often used in applications where both data and power transmission are required, such as in Power over Ethernet (PoE) applications.

How far can a hybrid cable supply power?

This means that the power supply distance can be quite long. According to Huawei's tests, hybrid cables can supply 60 W PoE power even at a distance of 300 m. That said, copper wires still have resistance, and thermal effect still occurs during transmission, meaning there is still some energy attenuation.
