Frequently Asked Questions

What is the product?

The product is a Free-Space Isolator that is Polarization-Dependent. It operates at one of the following wavelengths: 1310, 1480, 1550, or 1590 nm and it comes in two types: single stage or dual stage.

What is the operating wavelength range of the Isolator?

The operating wavelength range for the isolator is ±20 nm around the central wavelength of either 1310, 1480, 1550, or 1590 nm. This indicates the range within which the isolator can operate effectively.

What are the Isolation values for each stage type?

For the single stage isolator, the typical Isolation at 23℃ (room temperature) is 40 dB, and the minimum is 30 dB. For the dual stage isolator, the typical Isolation is 55 dB, and the minimum is 42 dB. Isolation refers to the extent to which the isolator prevents undesired signal flow in the opposite direction.

What are the Insertion Loss values for each stage type?

For the single stage isolator, the typical Insertion Loss at 23℃ is 0.2 dB, and the maximum is 0.25 dB. For the dual stage isolator, the typical Insertion Loss is 0.3 dB, and the maximum is 0.4 dB. Insertion Loss refers to the signal power loss as the signal goes through the isolator, so a lower value means more efficient transmission.

What is the Extinction Ratio?

The minimum Extinction Ratio is 30 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 maximum Optical Power Handling?

The maximum Optical Power Handling is 10 W/cm2. This is the maximum level of light power per unit area that the isolator can handle without being damaged.

What are the operating and storage temperatures?

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

How can I order this product?

To order this product, you should contact Ascentta directly. The company allows you to specify custom configurations, including type, stages or layers, packaging, wavelength, clear aperture, package dimension, input and output polarization angle.

What do different polarization angles represent?

The different polarization angles like 0 Degree, 45 Degree, 90 Degree, -45 Degree, -90 Degree represent the orientation of the electric field vector in the plane perpendicular to the direction of propagation. You can specify the desired input and output polarization angles based on your application needs when ordering.

What is the effect of using a latching type stage?

A latching stage type maintains the state of polarization after the power is removed. This is contrasted with the non-latching stage type, which doesn't hold the state of polarization after power removal. The type you choose depends on your specific application requirements.

What are the clear aperture options?

The available clear aperture options are 0.5mm, 0.9mm, and 1.2mm. The clear aperture is the open area through which light can pass in the optical system. You can specify the clear aperture based on your application needs when ordering.

What should I do to specify package dimensions?

You should contact Ascentta directly with your specific requirements for package dimensions. The company allows custom configurations and can cater to your specific requirements for this isolator.
