Fibre Optic Adapters

What is a Fibre optic adapter?

RS Components offer a wide selection of fibre optic adapters. A fibre optic adapter is used to connect and align two fibre optic connectors together. They are used to bridge the gap between a cable to cable fibre connections and sometimes known as a mating sleeve or a hybrid adapter. They come in different connection variations, either, single, double or sometimes quad. This is commonly known as single-mode or multi-mode fibre cable connection.

How does it work?

Fibre optic connections can provide a more accurate alignment for the tips of the connectors rather than using traditional connection methods such as soldering.

Single-mode adapters offer more precise alignment and can also be used to connect multi-mode cables. Multi-mode adapters should not be used to connect single-mode cables as this can cause alignment problems resulting in a loss of signal strength.

The most important element of a fibre optic adapter is the alignment sleeve. Bronze sleeves tend to provide more durability with the precision not as good, ceramic sleeves provide better precision alignment with durability not as good. Bronze sleeves are typically used in multi-mode adapters where precision is not as important.


What different types are there?

There are many types of fibre optic adapters, the most common connectors available, SC-to-SC, ST-to-ST, or FC-to-FC–and different styles of connectors. The latter devices are referred as hybrid adapters and typically used to join ST and SC connectors.
