The ceramic ferrule technology is growing in demand over the varied uses. They are of a little high price but make the things a deciding factor when it comes to choosing the items. This is actually the fiber and optical technology that is being promoted for the fiber-optic communications. They however make the cost lower without compromising with the performance. When you are talking about an optical connector the most important part is the ferrule.
The ceramic ferrules are durable. There is a much higher level of control over the dimension. They are good for using in the fiber applications. The zirconia material present in them enables a smooth polishing. Thus, there is a good surface finish. Use of modern technologies has made molding and machining of the ferrules more convenient that it had been earlier. They are proper for both single mode and multimode application.
They are used in the shell inlet and also in the tube like heat exchangers. These offer protection against the hot gases and abrasive particles. They are used in several industries. They are helpful for connecting the fibre optic cables.
Why zirconia is used
There are several advantages of using the zirconia material. They are crack free. The smoother finishes are achieved with smaller grains. The properties of it make it impact resistant.
Properties of ceramic ferrule:
• The ceramic ferrule is generally opaque.
• They need polishing.
• The ceramic ferrule has a higher bending strength than the normal glass materials.
• The expansion capacity is much lower than other materials.
• It provides strong contact with the optical connectors.
• The thermal expansion causes less stress.
• There are very less fibers present.
• A glass made ferrule is softer than others.
• The polishing costs of them are much less.
The single mode connectors have aligned fibre cladding in the centre axis. The width is within 2 micron. The connector whole diameter is matched carefully to the real fibre diameter. A large hole as an active alignment is used as an alternative.
If you are buying the single mode then do remember that it is a bit time consuming to assemble. Whereas the multimode ferrule connectors have a 128 micron outlet for a 125 micron fibre. So, between the two, the multi mode connectors are better options to choose. When you are thinking of buying them ensure that you buy from a reputed manufacturer so that you get value for money products.
