FAQ
1. What should I be aware of with the version with connector?
The page states that adding a connector typically increases insertion loss by 0.3dB, reduces return loss by 5dB, and reduces extinction ratio by 2dB. The default connector key is aligned with the slow axis. For polarization-maintaining systems, it is recommended to specify the axis, connector type, and port definition during procurement.
2. How do you ensure product quality and consistency before shipment?
As a professional supplier of polarization-maintaining passive components, we can test insertion loss, splitting ratio, extinction ratio, return loss, directivity, axial alignment, port definition, connector end face, and appearance. This page shows that the product is ISO9001 and RoHS certified, with an MOQ of 1 piece and a monthly supply capacity of 100,000 pieces, supporting both sample verification and bulk delivery.
