Frequently Asked Questions

Who is the provider of this product?

The provider of this product is Ascentta, a company specializing in optical solutions. They are located at 370 Campus Dr. Suite 105, Somerset, NJ 08873.

What is the Operating Range of the Circulator?

The Operating Range of this circulator is ±20 nm. This is the range around the central wavelength within which the circulator can operate effectively.

What is the Transmitting Direction?

The transmitting direction for this circulator is 1→2, 2→3. This means that signals enter at Port 1, exit at Port 2, then enter Port 2 and exit at Port 3. This directionality is typical of optical circulators.

What are the Isolation values?

The typical Isolation at 23℃ (room temperature) is 35 dB, and the minimum is 28 dB. Isolation refers to the extent to which the circulator prevents undesired flow of signal back into a port.

What are the Insertion Loss values?

The typical Insertion Loss at 23℃ is 0.6 dB, and the maximum is 0.8 dB. Insertion Loss refers to the signal power loss as the signal goes through the circulator, so a lower value means more efficient transmission.

What is the Extinction Ratio?

The minimum Extinction Ratio is 20 dB. This is a measure of the power contrast between two polarization states in a signal. A higher Extinction Ratio signifies better performance in maintaining polarization-dependent transmission.

What is the Return Loss?

The minimum Return Loss is 50 dB. This is a measure of the power that is lost to reflections when a signal enters the circulator. A higher Return Loss indicates less power is lost, which is better.

What is the Directivity value?

The minimum Directivity for this circulator is 50 dB. This measures how well the circulator transmits power in the desired direction while minimizing power transmission in the opposite direction. A higher Directivity indicates better performance.

What is the maximum Optical Power Handling?

The maximum Optical Power Handling is 300 mW. This is the maximum level of light power that the circulator can handle without being damaged.

What are the operating and storage temperatures?

The Operating Temperature range is from -5 to 70 degrees Celsius, and the Storage Temperature range is from -40 to 85 degrees Celsius. These ranges indicate the temperatures within which the circulator can operate safely and be stored without damage.

How can I order this product?

To order this product, please contact Ascentta directly. Please mention any custom configurations needed.

What is the difference between a Non-Latched Garnet vs a Latched Garnet?

The Non-Latched Garnet has a magnetic ring which maintains the polarization rotation of the signal and is ideal for higher temperature applications. The Latched Garnet also maintains polarization without the need for the bias magnet, thus making the isolator a more compact device, but may not be ideal at higher temperatures. If unsure, please feel free to talk to an Ascentta technical salesperson.

What are the available Clear Aperture options?

The available clear aperture options are 1.0mm, 1.5mm, and 2.0mm, Not all CA are available with all packages. The clear aperture is the open area through which light can pass in the optical system.

What are the package dimension options?

Standard package dimensions are 7.0x7.0x5.0mm (package 01) and 4.5x4.5x4.5mm (package 02). Please contact Ascentta for specific package dimension needs.
