Photoelectric hybrid cable is a new type of cable that combines optical cable and electrical cable. Hybrid fiber optic cable integrates optical fiber and power transmission copper wire as a transmission line, which can solve problems such as broadband access, equipment power consumption, and signal transmission. Next, let us learn what exactly a Photoelectric fiber optic cable is.
Photoelectric hybrid cable is a type of cable that combines optical fiber and electrical cable. It transmits optical signals through the optical fibers, enabling high-speed data communications, while also transmitting electrical signals through the electrical cable, providing stable power for devices. Externally, an hybrid fiber optic cable is typically round or butterfly shaped, with thickness varying depending on specifications. Peeling back the outer sheath reveals a sophisticated and orderly internal structure: tightly packed optical fibers surrounded by conductive copper wires that transmit electrical energy. The outermost layer is a sheath, protecting against mechanical damage, chemical corrosion, and moisture intrusion.
Optical signal transmission. Light propagates in optical fibers based on the principle of total internal reflection. Just like light bouncing back and forth between mirrors, light continuously reflects within optical fibers, enabling long-distance transmission. Singlemode and multimode optical fibers differ. Singlemode fiber is suitable for long distance, high speed signal transmission, while multimode fiber is often used for shorter distance communications. Furthermore, wavelength division multiplexing (WDM) technology allows multiple optical signals of different wavelengths to be transmitted simultaneously within a single optical fiber, significantly increasing transmission capacity.
Power transmission. Conductive copper wires transmit electricity through electric current. This process generates heat due to the inherent resistance of the copper wires, resulting in energy loss and limiting the power supply distance.
Optical and electrical signals are prevented from interfering with each other within a single cable thanks to hybrid optical cable’s unique structural design. For example, the optical fiber and the conductive copper wire are separated by an insulating layer and sheath. The fiber's glass fiber material and the insulating shielding properties of the sheath ensure stable transmission of both optical and electrical signals without affecting each other.
The biggest advantage of hybrid fiber optic cable is space and cost savings. Hybrid fiber optic can transmit both optical and electrical signals simultaneously, have a small outer diameter, and are lightweight. Hybrid wire are also more convenient to install, significantly reducing both procurement and construction costs. Hybrid optical cable offer excellent bending and lateral pressure resistance, making them adaptable to various installation methods, including overhead, ducted, and direct buried. Furthermore, hybrid cable’s high bandwidth meets the needs of transmitting large amounts of data. They are highly adaptable to various transmission protocols and device interfaces, offering strong scalability.
In summary, the photoelectric hybrid cable has long transcended the positioning of a single transmission tool, hybrid fiber optic cable achieves the connection between digital systems and energy networks through the superposition of its advantages. With the advancement of new infrastructure construction, hybrid fiber optic cable will also evolve toward being slimmer and more high performance in the future.
