Frequently Asked Questions

What should one specify when contacting Ascentta for a custom configuration?

When contacting Ascentta for a custom configuration, one should specify details like port, wavelength, fiber type, cable type, fiber length, connector, maximum power, and package.

What does 'PMVCIR3=3-Port' mean in the ordering information?

'PMVCIR3=3-Port' refers to the number of ports the circulator has. In this case, it is a 3-port device.

What does 'PM=Polarization-Maintaining' imply in the ordering information?

'PM=Polarization-Maintaining' refers to the type of fiber used in the circulator. A polarization-maintaining fiber preserves the polarization of the light as it travels through the fiber.

Can other configurations be specified when ordering?

Yes, other configurations can be specified when ordering. 'X=Others' is provided as an option in the ordering information for different categories.

How to specify cable type, fiber length, connector, maximum power, and package when ordering?

Each of these options has corresponding codes provided in the ordering information. For example, for fiber length '10=1.0m', '15=1.5m', '20=2.0m', '30=3.0m' and 'X=Others' for any other length. Similar codes exist for cable type, connector, maximum power, and package.
