Frequently Asked Questions
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.
The Operating Range of this circulator is ±20 nm. This is the range around the central wavelength within which the circulator can operate effectively.
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.
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.
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.
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.
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.
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.
The maximum Optical Power Handling is 300 mW. This is the maximum level of light power that the circulator can handle without being damaged.
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.
To order this product, please contact Ascentta directly. Please mention any custom configurations needed.
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.
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.
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.
