product description
The 4-Port Mini Fiber Circulator is an advanced optical component designed to direct the flow of light signals in a specific sequence through its ports. This device is crucial for applications that require controlled routing of optical signals. Here's a summary of its key features and their benefits:
Signal Routing: 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 function is essential for setting up the correct path for light signals in complex optical networks.
High Isolation: The circulator provides high isolation, which means it effectively blocks light from being transmitted back to the previous port. This feature minimizes signal interference and ensures that the signal integrity is maintained.
Low Insertion Loss: With low insertion loss, the circulator ensures that the power of the light signal is minimally reduced as it passes through the device. This is important for maintaining signal strength, especially in long-distance fiber optic communication systems.
Low Polarization Dependent Loss (PDL): The circulator has low PDL, which means it maintains consistent performance regardless of the polarization state of the input light. This feature is important for ensuring reliable signal transmission.
Low Polarization Mode Dispersion (PMD): 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.
Excellent Environmental Stability: The component is designed to maintain its performance under varying environmental conditions, such as temperature fluctuations. This stability is essential for reliable operation in diverse settings, including outdoor or uncontrolled environments.
