Frequently Asked Questions

What type of circulator is this?

This is a 3-Port Optical (TGG Type) Circulator, specifically a Single-Mode type. It is designed for wavelengths 532, 635, 650, 780, 850, 980, 1030, and 1060 nm.

What is the typical and minimum isolation at 23°C for each wavelength?

For 532, 635, 650 nm the typical isolation is 23 dB and the minimum is 20 dB. For 780, 850 nm the typical isolation is 25 dB and the minimum is 21 dB. For 980, 1030, 1060 nm the typical isolation is 27 dB and the minimum is 22 dB.

What is the maximum insertion loss (All SOP) for each wavelength?

For 532, 635, 650 nm the maximum insertion loss is 2.5, 2.3, and 2.3 dB respectively. For 780, 850 nm the maximum insertion loss is 1.8 dB. For 980, 1030, 1060 nm the maximum insertion loss is 1.5 dB.

What is the maximum PDL and PMD for each wavelength?

The maximum PDL and PMD for all wavelengths is 0.2 dB and 0.2 ps, respectively.

What is the minimum return loss and directivity for each wavelength?

The minimum return loss and directivity for all wavelengths are 45 dB and 40 dB, respectively.

What is the maximum optical power handling for each wavelength?

For 532 nm the maximum optical power handling is 50 mW, for 635, 650 nm it's 100 mW, for 780, 850 nm it's 150 mW, and for 980, 1030, 1060 nm it's 250 mW.

What is the dimension of the package for each wavelength?

The package dimensions are Φ21xL60 mm for 532 nm, Φ21xL75 mm for 635, 650 nm, Φ24xL80 mm for 780, 850 nm, and Φ24xL95 mm for 980, 1030, 1060 nm.

What are the guidelines for ordering a custom configuration?

Contact Ascentta with your custom configuration needs, specifying the port, wavelength, fiber type, cable type, fiber length, connector, maximum power, and package. For example, 'VCIR3=3-Port', '532=532nm', 'S=Single-Mode' for fiber type, etc. The given codes such as 'B=250um', 'L=900um' etc., should be used to specify cable type and other options.
