Fiber optic connectors and adapters are essential components in the installation of fiber optic cables either in FTTX applications or within a local area networks. The need to provide reliable and discreet connections among different cables is increasing, making the selection of fiber connectors important for the system designer. Here, we will discuss the SW20-LCA-1 connector adapter and its applications and working principle.

Technical Specifications

The SW20-LCA-1 is an SC/LC-type duplex adapter manufactured by the Applied Optics Corporation. It is designed to connect two fiber optic cables with different connector types, such as SC-to-LC. It has a proven reliable performance and is supported by a tested insertion loss. In addition, the connector adapter also has a low back-reflection characteristics.

Application

The SW20-LCA-1 connector adapter is most suitable for use in local area network (LAN) and fiber-to-the-home (FTTH) applications. In FTTX deployments, the adapter can be used to connect SC and LC-type patch cables with different connectors. The adapters are also suitable for connecting single-mode and multi-mode cables as they have the correct physical dimensions and ferrule alignment.

Working Principle

The SW20-LCA-1 is a type of optical connector adapter which is designed to facilitate the connection between two fiber optic cables with different connector types. The adapter is composed of two parts; a front part which comprises the SC-style connector, and a rear part which includes the LC-style connector. When the two connectors are inserted into the adapter, a spring-loaded sleeve mechanism ensures proper alignment of the two connectors and ensures a secure connection.

The adapter also functions as an optical coupler, which allows the signal from one cable to be transmitted to the other. This is accomplished by two optical elements; a rear element which transmits the signal from the LC to the SC connector, and a front element which transmits the signal from the SC to the LC connector. These elements ensure an optimal signal quality is maintained throughout the connection.

Conclusion

The SW20-LCA-1 is a reliable and efficient connector adapter, suitable for use in both FTTX and LAN networks. The use of two optical elements ensures that the signal remains stable and of an acceptable quality. As such, it is a useful tool for fiber link designers in these applications.
