FAQ
Q1: What operating wavelengths does this PM Isolator support?
A: This product supports common communication wavelengths such as 1310nm, 1480nm, and 1550nm, with an operating bandwidth of ±20nm. Wavelength options such as 1064nm and 1650nm are also available 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 isolation, high extinction ratio, high return loss, and high stability. The single-stage model achieves a peak isolation of 40–42dB, while the dual-stage model achieves a peak isolation of 55–58dB; return loss is ≥55dB, and the maximum power handling capacity is ≤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 position is aligned with the slow axis and blocked by the fast axis.
