1, FC fiber adapter:
The external reinforcement is the use of metal sets, fastening for the screw buckle. FC type adapter, using the butt end of the ceramic pin. This kind of adapter has the advantages of simple structure, easy operation and easy manufacture, but the fiber end face is more sensitive to dust, and it is easy to produce Fresnel reflection, and it is difficult to improve the return loss performance. Later, the type of connector has been improved, the use of docking face spherical face (PC), while the external structure has not changed, making the insertion loss and return loss performance has been greatly improved.
2, SC fiber adapter:
Its shell is rectangular, the use of the pin and coupling sleeve structure size and FC type exactly the same. Which pin the end of the use of PC or APC-type grinding method; fastening method is to use plug-and-pin type, without rotation. Equipped with metal shrapnel, easy to conceal use. Such connectors are inexpensive, easy to plug and operate, small fluctuations in interventional losses, high compressive strength, high mounting density.
3, ST fiber adapter:
For the keyed locking structure, to ensure accurate alignment of the connection, with a strong tensile strength, metal key positioning, improve the repeatability and durability of the adapter, the use of precision ceramic or copper sleeve to ensure that Long-term stability of the mechanical properties and optical properties. Rectangular structure, tapping riveting installation easy to use.
4, LC fiber adapter:
It is made with a convenient modular jack (RJ) latch mechanism. The size of the pins and sleeves used is small, increasing the density of the fiber optic connectors in the fiber patch panel. The use of precision ceramic sleeve, to ensure long-term stability of the mechanical and optical properties.
