The interface types of optical modules include FC type, SC type, LC type, ST type, and KTRJ type.
1. The FC connector adopts a threaded locking mechanism, which is one of the earliest and most commonly used fiber optic active connectors.
2. SC is a rectangular connector that does not require threaded connections and can be directly inserted and removed. Compared with FC connectors, it has smaller operating space and is convenient to use. Low end Ethernet products are very common.
3. LC is a Mini type SC connector with a smaller volume, which has been widely used in systems and is a direction for the development of fiber optic active connectors in the future. Low end Ethernet products are very common.
4. ST connectors use a bayonet locking mechanism, with main parameter indicators comparable to FC and SC connectors. However, they are not commonly used in company applications and are usually used for multi-mode device connections. They are more commonly used when docking with equipment from other manufacturers.
5. The pins of KTRJ are made of plastic and positioned through steel pins. As the insertion and extraction times increase, various mating surfaces will wear out, and their long-term stability is not as good as ceramic pin connectors.
