Polarization Maintaining Filter Coupler
The Polarization Maintaining Filter Coupler offered by Flyin Optronics Co., Ltd. is a precision fiber‑optic component built from silica fiber with a polymer coating. It is designed to preserve the state of polarization of light signals, delivering low excess loss and a high polarization extinction ratio. The device is targeted at telecommunications, lidar and sensing systems that require stable polarization control. Supplier data confirms the component is a passive photonic part intended for integration into fiber‑optic networks and test equipment.
In the broader market, PM couplers typically exhibit insertion loss of 0.3 - 0.5 dB and a polarization extinction ratio of 20 dB or greater. Standard operating wavelengths are the telecom bands at 1310 nm and 1550 nm, and they are normally paired with single‑mode PM fibers. Common connector formats are FC/PC or LC, housed in a metal enclosure with an anti‑static protective bag. These typical parameters align with IEC 61753‑1 requirements for optical components.
Telecom operators, lidar manufacturers and research laboratories purchase such couplers to ensure signal integrity in high‑speed data links and precision measurement setups. Flyin Optronics indicates that order quantities can be adjusted to project size, and they list FOB and CIF shipping options for buyers. Packaging is described as secure metal housings placed in anti‑static bags to minimise damage during transit. Prospective importers should request a formal quotation to confirm any minimum order quantity, lead time and payment conditions.

Sourcing Polarization Maintaining Filter Coupler from Flyin Optronics Co., Ltd. - China Import Guide
Before placing an order, importers should obtain a detailed data sheet that confirms the material (silica fiber with polymer coating), insertion loss, and polarization extinction ratio. Request a sample or a recent test report to validate that the coupler meets the typical specifications described. Verify that the supplier can provide any required certifications, such as IEC 61753‑1 compliance, even if they are not listed in the product entry. Clarify the minimum order quantity and any customisation options directly with Flyin Optronics.
Shipping terms are typically offered as FOB or CIF, so buyers must decide which responsibility level matches their logistics strategy. Lead time for optical components of this class commonly ranges from four to six weeks, but the exact schedule should be confirmed with the supplier. Payment methods often include telegraphic transfer (T/T) or a confirmed letter of credit (L/C), and the preferred option should be negotiated early. Ensure that the commercial invoice clearly states the HS code for optical fiber components to avoid customs delays.
Conduct a pre‑shipment inspection, focusing on connector integrity, housing condition and the presence of anti‑static packaging. Request the supplier’s ISO or RoHS certificates, as well as the IEC 61753‑1 test report, to substantiate product quality. If large volumes are ordered, consider hiring a third‑party inspection agency to verify performance parameters on site. Keep copies of all test reports and certificates for future reference and for compliance with import regulations.
