Fiber optic adapters are the most used optical passive components in fiber-optic communication systems. Most fiber optic connectors consist of three components: two fiber optic connectors and one coupler. Two fiber optic connectors are fitted into the two fiber ends; the coupler functions as an alignment sleeve. In addition, the coupler is often equipped with a metal or non-metal flange to facilitate the installation and fixing of the connector.
The fibers are connected by adapters through their internal open sleeves to ensure maximum connection performance between the fiber connectors. In order to be fixed on various panels, a variety of fine fixing flanges have been designed.
The conversion adapter can be connected to fiber connectors of different interface types at both ends, and provides a connection between the APC end faces. The double or multi-coupler can increase the installation density and save space.

The Combination of SC Adapter And FC Adapter:
SC-FC optical adapter is for connecting SC connector and FC connector in the optical network, it is a combination for them.
According to the difference in appearance structure and docking section, fiber adapters can be roughly divided into the following common models: FC, SC, ST, LC, FC-SC, FC-ST, ST-SC, in addition to some male to female Connect to fiber optic adapter.
FC fiber adapter: The external reinforcement method is a metal sleeve, and the fastening method is a screw buckle. FC type connector, butt end of ceramic pins. This type of connector is simple in structure, easy to operate, and easy to manufacture, but the fiber end is more sensitive to dust, and Fresnel reflection is easy to produce, and it is more difficult to improve the return loss performance. Later, this type of connector was improved, using a spherical pin (PC) with a mating end face, and the external structure was not changed, which made the insertion loss and return loss performance greatly improved.
SC fiber optic adapter: The outer shell is rectangular, and the structural dimensions of the pin and coupling sleeve used are exactly the same as the FC type. Among them, the end surface of the pin is mostly PC or APC type grinding method; the fastening method is the plug pin type, without rotating. Equipped with metal shrapnel for easy concealed use. This type of connector is inexpensive, easy to plug and unplug, has small fluctuations in insertion loss, has high compressive strength, and has a high installation density.
Opportunity of Fiber Optical Devices In 5G Construction:
The "revolution" detonated by 5G will subvert the traditional Internet and will also greatly change our way of life. With the help of 5G technology, it can provide VR, AR, large-scale Internet of Things, unmanned driving, telemedicine, intelligent buildings, etc. Technology provides unprecedented innovative design, and the whole society is actively welcoming the arrival of 5G. The demand for optical devices will be detonated as the 5G construction moving forward.
