product description
The 4-Port Mini Fiber Circulator is an essential component in optical communication systems, particularly in Dense Wavelength Division Multiplexing (DWDM) networks and other high-speed applications. Here's a summary of its key features and applications:
The circulator routes incoming signals in a sequential manner: from Port 1 to Port 2, Port 2 to Port 3, and Port 3 to Port 4. This functionality is crucial for directing optical signals within complex networks.
The miniaturized design of the circulator makes it suitable for applications where space is limited, allowing for more components to be integrated into a smaller footprint.
The component provides high isolation, which means that the signal transmitted from one port to the next is effectively blocked from being transmitted back. This minimizes signal interference and ensures signal integrity.
With low insertion loss, the circulator ensures that the power of the optical signal is minimally reduced as it passes through the component, maintaining signal strength.
The circulator has low PDL, which means it maintains consistent performance regardless of the polarization state of the input light, ensuring reliable signal transmission.
The low PMD of the circulator helps to reduce the variation in signal transmission times due to polarization, which is critical for high-speed data transmission.
The 4-Port Mini Fiber Circulator is a high-performance, reliable component that enhances the efficiency and reliability of optical communication systems, making it a valuable asset in modern telecommunications infrastructure.
