1. Speed: 

 Bandwidth Capacity: fibre optic patch leads have a much higher bandwidth capacity compared to copper cables. While copper cables typically support bandwidths up to 1 Gbps or 10 Gbps, fibre optics can supply bandwidths ranging from 10 Gbps to 100 Gbps and beyond. This increased ability allows for the seamless transfer of large files, video streaming, and real-time data-intensive applications. 

Futureproofing: fibre optic patch leads offer better scalability and future-proofing capabilities. As technology advances and data demands continue to grow exponentially, fibre optics can easily accommodate higher speeds by upgrading the network equipment and not the entire cabling infrastructure. However, copper cables may need complete replacement to keep up with future bandwidth requirements. 

Speed Comparison: A single fibre optic strand can send 3.2 terabits of data per second, equivalent to transmitting 2,500 high-definition movies in just one second. In contrast, copper cables are limited to lower speeds, with Cat6 cables supporting up to 10 Gbps. 

2. Distance:

Signal Integrity: fibre optic patch leads to support signal integrity over long distances due to low attenuation (signal loss). This means that even over extended distances, the data is still intact and does not require added signal amplification or regeneration. Copper cables, in contrast, suffer from higher attenuation, leading to a degradation of the signal quality over distance. 

Lossless Transmission: fibre optic cables enable lossless transmission of data over long distances. The absence of signal degradation ensures that the information arrives at its destination without errors or the need for retransmission. This is particularly crucial for applications such as high-definition video streaming, cloud computing, and real-time data transfers. 

Submarine Communication: fibre optic cables are extensively used for long-distance submarine communication. For example, the SEA-ME-WE 3 (South-East Asia – Middle East – Western Europe 3) submarine cable system, spanning approximately 39,000 kilometres, connects 33 countries and territories, supplying reliable data transmission across continents. 

3. Reliability: 

 Security: fibre optic patch leads offer enhanced security compared to copper cables. The nature of fibre optics makes it difficult to tap into the cable and intercept the data transmission, supplying an added layer of security against unauthorized access. Copper cables, on the other hand, can be vulnerable to eavesdropping or electromagnetic interference. 

Immunity to Electromagnetic Interference (EMI): fibre optic cables are immune to EMI since they send light signals instead of electrical currents. This immunity makes them exceptionally reliable in environments with high EMI, such as industrial settings or areas with heavy machinery. Copper cables, being susceptible to EMI, may experience signal disruptions or data corruption in such environments. 

Resistance to Interference: fibre optic patch leads are immune to electromagnetic interference, ensuring reliable data transmission even in environments with prominent levels of electrical noise. This immunity makes them ideal for deployment in areas near power lines, electrical substations, or industrial facilities where copper cables may be susceptible to interference. 

Mean Time Between Failures (MTBF): fibre optic cables have a significantly higher MTBF compared to copper cables. Fibre optic cables have an average MTBF of 25 years or more, showing their long-term reliability. Copper cables typically have a lower MTBF, ranging from 5 to 15 years.  

Safety: fibre optic cables are safer to handle and use than copper cables. Since fibre optics do not carry electrical current, there is no risk of electric shocks or short circuits during installation or maintenance. Copper cables, on the other hand, require proper grounding and precautions to prevent electrical accidents. 

Maintenance and Durability: Fibre optic patch leads require minimal maintenance compared to copper cables. fibre optics are not affected by corrosion, rust, or moisture, making them exceptionally durable in various environmental conditions. Copper cables may require regular maintenance, including checks for oxidation, cable bends, and connector damage.
