In fusion splicing machines, choosing the right material for the V-shaped fibre optic groove is crucial. And blue zirconia has become a favoured option. This is due to its multiple advantages in meeting high demands for visibility, abrasion resistance and reflectivity.

Firstly, visibility is an important consideration. By using a V-shaped fibre slot made of blue zirconia, operators can more easily observe and identify whether the fibre is correctly placed in it. Its distinctive colour provides good visibility and contrast, reducing errors and increasing efficiency during operation.

The data shows that with blue zirconia V-grooves, there is a significant reduction of more than 25% in the number of misplaced or damaged fibres leading to loss of signal compared to traditional black or white V-grooves, further demonstrating the positive impact of blue zirconia in improving visibility.

Secondly, wear resistance was one of the reasons for choosing blue zirconia. As friction affects the stability of the fibre in its position inside the V-groove, a robust and durable material is needed to ensure that long-term use is not a problem. Blue zirconia, on the other hand, has high hardness and wear-resistant properties that can withstand the challenges of frequent use.

According to experimental data, blue zirconia V-grooves show better wear resistance than conventional materials after a large number of fibre-optic connection operations, with half the surface wear, which means that the choice of blue zirconia extends the service life of V-grooves and reduces maintenance and replacement costs.

In addition, blue zirconia has a lower reflectivity. Compared to white materials, it reduces the reflection of optical signals on contact surfaces and reduces signal loss. This is important to ensure that fibre optic transmission efficiency is maximised.
According to measurements, after using blue zirconia to manufacture the V-groove, the average reflection loss incurred during signal transmission was reduced by approximately 15 percent, which indicates that the blue zirconia material provides a more reliable fibre-optic connection, helping to maintain the signal quality and stability of the data transmission.

Finally, thermal conductivity is also an advantage in choosing blue zirconia. During high power or prolonged use, the heat generated needs to be dissipated quickly to maintain a stable temperature. Blue zirconia typically has good thermal conductivity properties, which can help disperse and dissipate heat.
