FAQ

Q1: What operating wavelengths does this PM Isolator support?

A: This product primarily supports common communication wavelengths such as 1310nm, 1480nm, and 1550nm, with an operating bandwidth of ±20nm. Wavelengths such as 1064nm and 1650nm can also be selected in the ordering information, allowing for configuration according to different system requirements.

Q2: What are the main performance advantages of this polarization-maintaining isolator?

A: This product features low insertion loss, high extinction ratio, high isolation, high stability, and high reliability. The peak isolation of the single-stage model can reach 40–42dB, and the peak isolation of the dual-stage model can reach 55–58dB; return loss ≥55dB, and maximum power handling ≤300mW.

Q3: Does this PM Isolator support customization?

A: Customization is supported. Customers can choose the operating wavelength, single/dual-stage structure, slow-axis or dual-axis operation, packaging type, fiber sheath, fiber length, and connector type according to their needs. Connectors are available in FC/UPC, FC/APC, SC/UPC, SC/APC, LC/UPC, LC/APC, or other custom specifications; the default connector key alignment is with the slow axis.
