Frequently Asked Questions

What is the product?

The product is a Single-Mode Polarization Insensitive Isolator. It operates in the C+L Band, and it comes in two types: single stage or dual stage.

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 wavelength range of the Isolator?

The operating wavelength range for the isolator is 1530-1610 nm. This falls within the C+L Bands, which is a combination of C-Band (1530-1565 nm) and L-Band (1565-1625 nm) commonly used in optical communication systems.

What are the Isolation values for each stage type?

For the single stage isolator, the typical Isolation at 23℃ (room temperature) is 32 dB, and the minimum is 28 dB. For the dual stage isolator, the typical Isolation is 50 dB, and the minimum is 40 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 0.4 dB, and the maximum (from -5 to 70℃) is 0.6 dB. For the dual stage isolator, the typical Insertion Loss is 0.6 dB, and the maximum (from -5 to 70℃) is 0.8 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 PDL value?

The maximum Polarization Dependent Loss (PDL) is 0.1 dB for both single stage and dual stage isolators. PDL is the difference in attenuation that occurs due to changes in the polarization state of light.

What is the PMD value?

The maximum Polarization Mode Dispersion (PMD) is 0.25 ps for non-compensated single-stage parts and 0.05 ps for dual-stage isolators. PMD is a time delay between different polarization modes of light, which can affect signal quality in high-speed systems.

What is the Return Loss?

The minimum Return Loss for both input and output is 50 dB for both single stage and dual stage. Return Loss is a measure of the power that is lost as light is reflected back towards the source. A higher Return Loss signifies lower reflection and 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 isolator can handle without being damaged.

What fiber type is used in this Isolator?

The Isolator uses SMF–28 type fiber. SMF-28 is a type of single-mode optical fiber that is commonly used in telecommunications applications.

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 isolator can operate safely and be stored without damage.

What is the package dimension?

The Package Dimension for this isolator is Φ5.5 x L35 mm.

How do connectors affect the Isolator?

The specifications provided are for parts without connectors. Adding connectors can affect the Insertion Loss, Return Loss, and PDL of the isolator.

How can I order this product?

To order this product, you should contact Ascentta directly. The company allows you to specify custom configurations, including stages, wavelength, fiber type, fiber length, connectors, and package.

What fiber types are available?

The available fiber types are SMF-28 with diameters of 250um and 900um. These are single-mode fibers that are commonly used in telecommunications applications. You can specify the fiber type based on your application needs when ordering.

What fiber lengths are available?

The available fiber lengths are 1.0m, 1.5m, 2.0m, and 3.0m. You can specify the fiber length based on your application needs when ordering.

What connector types are available?

The available connector types are FC/APC, FC/PC, SC/APC, SC/PC, ST/PC, LC/APC, and LC/PC. You can specify the connector type based on your application needs when ordering. Each type of connector has its own features and suitability for different applications. For instance, APC connectors provide a lower back reflection than PC connectors, making them better suited for high-speed digital systems or analog video systems.
