FAQ
1. What specifications can be customized?
Customizable port structure, operating wavelength, splitting ratio, package size, fiber sheath, fiber length, and connector type. Standard fiber length is 1.0±0.1m. Connectors include FC/APC, FC/UPC, and SC, LC, or other custom connectors can also be provided upon request. The default connector key alignment is with the slow axis.
2. How do you ensure quality and batch consistency before shipment?
This product page shows ISO9001 and RoHS certifications, an MOQ of 1 piece, and a monthly supply capacity of 100,000 pieces. As a professional supplier of polarization-maintaining passive components, we can test insertion loss, additional loss, splitting ratio, extinction ratio, return loss, directivity, axial alignment, port definition, connector endface, and appearance. We support sample verification, small-batch trial production, and mass production.
