Fiber optic travelling cables are specialised data transmission mediums, mainly used for high speed data transfer. They use thin strands of glass or plastic fibers to transmit digital information over long distances. Copper cables, on the other hand, use copper conductors to transmit data using electrical signals.

Traditionally, copper cables have been used to transmit data and signals between the elevator car and the control room, but as the demand for a more reliable and future ready elevator system rises, fiber optic cables are becoming the highly sought after choice for building engineers. Today in this blog, we’ll explore why fiber optic travelling cables are a superior choice for data transmission over traditional copper cables and their various applications to help you understand which cable you should choose for your project.

Advantages of Fiber Optic Travelling Cables Over Copper Cables

Here are several factors that make fiber optic travelling cables a better choice than copper cables:

High Reliability

Fiber optic travelling cable can deliver uninterrupted data transmission even in an environment with high temperature, moisture exposure and electromagnetic interference where traditional copper cables tend to malfunction or degrade. As a result of this, fiber optics offer less service interruptions and seamless elevator operations that make them an ideal option for elevator shafts over copper cables.

High Data Transmission Speed

In copper cables data is transmitted through the movement of electrons, which means they transfer data at the speed of the electrons. On the other hand, in fiber optics, the data is transferred in the form of light, meaning that the speed of data transfer is approximately equal to the speed of light. This rapid data transfer in fiber optics allows for lightning fast communication between elevator systems and control panels. This feature supports real time monitoring and other advanced technologies used in modern elevators.

Low Attenuation

Signal attenuation refers to loss of signal strength over distance, which is a significant limitation with copper cables, which demand repeaters in every few kilometers. Fiber optic cables exhibit much lower attenuation in contrast. They maintain optimal signal quality over longer distances without frequent boosters. This advantage can be particularly beneficial in high rise buildings, where elevator shafts can span up to considerable heights.

Higher Bandwidth

Fiber optic cables offer bandwidth capacities exceeding 60 Tbps, far surpassing the 10 Tbps typically achievable with copper alternatives. This high bandwidth makes them ideal for supporting modern elevator features such as HD video surveillance, emergency communication systems and integrated building management solutions—all without lag or data bottlenecks.

Security Against Intrusion

Security is a top priority in building operations. Copper cables can be tapped relatively easily, which poses a risk of data theft or unauthorised access. Fiber optic cables, however, are extremely difficult to tap without detection. Thus, they offer a robust layer of security for sensitive elevator communications.

Non-Corrosive

Copper cables are prone to corrosion, especially in humid or corrosive environments, which can lead to failures and increased maintenance costs. Fiber optic cables, composed mainly of glass, are non-corrosive and maintain their integrity over time. As a result of their non-corrosive nature, they eliminate the need for frequent replacements.

Lightweight and Sturdy

Fiber optic travelling cables are significantly lighter and thinner than copper cables, which makes installing them easier and reduces the mechanical strain on elevator systems. Despite their lightweight nature, they are robust enough to withstand the constant flexing and movement required in elevator applications, and ensure a long service life.

Affordable Solution

While the upfront cost of fiber optic cables may be higher than copper, their longevity, minimal maintenance requirements and superior performance make them a cost-effective investment over the long term. Copper cables, on the other hand, might be cheaper, but they need frequent replacements and often malfunction, which increases the overall operational cost over time.

Futuristic Solution

As building technologies continue to evolve, the need for scalable, high-capacity data infrastructure becomes essential. Fiber optic travelling cables are future-proof, capable of supporting emerging smart elevator features and the high speed data demands of next-generation buildings. Upgrading copper cables to fiber optics now ensures that buildings can support technological advancements in years to come.

Applications

Fiber optic travelling cables are extensively used in elevator systems for transmitting control signals, real-time monitoring data, video feeds, and emergency communications between the elevator car and the control room. Their high reliability and bandwidth make them ideal for high-rise buildings, commercial complexes, hospitals, and smart buildings where seamless, secure, and high-speed data transmission is critical for safety and operational efficiency.

Conclusion

If you are in building construction or an engineer, looking for the right data transmission system for reliable elevator performance and future-proofing your projects, fiber optic travelling cables stand out as the superior choice over copper. Their unmatched reliability, speed, bandwidth, and security make them the ideal solution for modern elevator communication systems. However, make sure to buy from a reliable provider to ensure you are getting the best quality product and post-purchase support.
