Optical-Electrical Composite Cable Solves the Challenges of Long-Distance Power Supply and Transmission for Security Monitoring

“To power the most distant camera, we had to install a waterproof enclosure in between, filled with switches, power supplies and surge protectors. Yet it broke down twice in less than six months.” — This was the frustration voiced by the weak current project manager of a logistics park.

Such scenarios play out almost daily in security engineering projects. The 100-meter limit of PoE, difficulties in accessing power in outdoor areas, and high failure rates of intermediate nodes have turned supposedly reliable monitoring systems fragile. Yet all these issues are being quietly revolutionized by a new type of cable known as the optical-electrical composite cable.

The logic behind deploying security cameras is straightforward: cameras are installed wherever risks exist. However, risk points are often located in remote corners – at the far end of a factory fence, in the deepest recesses of a campus, or along suburban sections of highways.

Power supply difficulties: These locations usually lack pre-existing power sources. Running utility power involves high costs, slow approval processes, and increased risks of lightning strikes.

Transmission difficulties: Network cables suffer signal attenuation beyond 100 meters, leading to packet loss and lag even with extension efforts.

Maintenance difficulties: Repeaters or cabinets must be added to exceed the 100-meter limit, turning these intermediate nodes into hotbeds of failure.

Is there a solution that allows power and signals to flow directly from the equipment room to the farthest cameras like running water?

The POF (Phototronic Fusion) passive optical network solution launched by AINOPOL is built around the optical-electrical composite cable. It integrates optical fibers and conductive cores within a single sheath, enabling simultaneous optical signal transmission and DC power supply, and completely breaking the physical limits of transmission distance and power delivery capability.

Many contractors worry: can the optical-electrical composite cable deliver sufficient power over long distances? AINOPOL provides the answer with measured data:

High-power coverage (300 meters): For high-power devices (60W) such as high-speed dome cameras, facial recognition capture cameras, and bullet cameras with heating modules, the power supply distance reaches 300 meters – sufficient to cover main thoroughfares in most campuses.

Ultra-long distance coverage (800 meters): For light-load devices (around 15W) including perimeter beams, fixed bullet cameras, and small dome cameras, the power supply distance can be extended to 800 meters. This means only one power point is needed every 800 meters along fences, greatly reducing the number of power access points.

All-link relay-free: No active equipment exists along the entire link from the equipment room to cameras except at both ends, resulting in near-zero failure rates.

The optical fibers within the composite cable handle data communications, offering immunity to electromagnetic interference, high bandwidth, and low latency – perfectly suited for real-time transmission of 4K and even 8K video.

In campuses with sparse buildings, where cameras are mostly distributed along roads and fences, optical-electrical composite cables can be laid through pipelines or directly buried. Any point can access the network directly without intermediate power supply, achieving truly comprehensive coverage.

Highway surveillance requires camera groups every few hundred meters. Traditional solutions rely on densely distributed power boxes, while the AINOPOL solution supports 800-meter coverage from a single power point, drastically reducing the number of wayside cabinets and improving traffic safety.

For perimeters spanning dozens of kilometers, planning power supply every 100 meters is a nightmare. Optical-electrical composite cables extend the interval between power points to 800 meters with passive intermediate links, ensuring high stability and reliability – ideal for security scenarios demanding exceptional dependability.

The essence of security is to “detect risks”, not to maintain wiring. AINOPOL POF Phototronic Fusion Solution solves both power supply and transmission challenges with a single optical-electrical composite cable, restoring front-end cameras to a truly simple “plug-and-play” state.
