Frequently Asked Questions

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

There are two available types of this CWDM Module, a 4-Channel type and an 8-Channel type. The number of channels refers to the number of distinct optical signals that the module can handle simultaneously.

The Channel Spacing refers to the spectral distance between the wavelengths that the module uses for data transmission. For this CWDM Module, the Channel Spacing is 20 GHz.

The Center Wavelength Accuracy is a measure of how precisely the module can target the desired transmission wavelength. For this product, the Center Wavelength Accuracy is ± 0.5 nm, meaning the actual wavelength can vary by up to 0.5 nm from the intended target wavelength.

The Bandwidth at -0.5dB is a measure of the spectral width of the channel at which the signal power falls to -0.5 dB below its peak power. For this product, the minimum Bandwidth at -0.5dB is 13 nm.

Insertion Loss is a measure of the power loss of the signal as it passes through the module. It's an essential parameter since lower Insertion Loss means more efficient transmission. For the 4-Channel CWDM Module, the maximum Insertion Loss is 1.8 dB, and for the 8-Channel CWDM Module, the maximum Insertion Loss is 2.6 dB.

The maximum Optical Power Handling is the maximum level of light power that the module can safely handle without being damaged. For this product, the maximum Optical Power Handling is 300 milliwatts (mW).

To order this product, you should contact Ascentta directly. The company allows you to specify custom configurations, including the number of channels, start channel, fiber type, fiber length, connector type, and whether an express port is required.

Connectors are used to join optical fibers and allow light signals to pass from one fiber to another. However, adding connectors can introduce additional Insertion Loss (IL), Return Loss (RL), and Polarization Dependent Loss (PDL). These losses can affect the overall performance of the optical module, so it's essential to factor in these changes when designing a system using this product.

The physical dimensions of the package containing the product are 110x95x8 mm. It's important to know the size for considerations related to installation space and transport logistics.

SOP, or State Of Polarization, refers to the orientation of the electric field vector in the light wave produced by the optical module. Polarization is an essential aspect of light wave propagation, especially in fiber optic communications, where certain effects like Polarization Mode Dispersion (PMD) can affect signal quality. In the given specifications, SOP refers to the conditions under which the measurements were taken.
