Import 1550/980nm Polarization Maintaining Filter Wdm — Buy in wholesale FOB from Supplier in China

This 1550/980nm Polarization Maintaining Filter Wavelength Division Multiplexer (WDM) from Ruik-Tech Communication Co.,LTD. is a passive optical component engineered for combining or separating signals at 1550 nm and 980 nm wavelengths while preserving the polarization state of the transmitted light. The device is built for low insertion loss and high channel isolation, which are critical parameters for maintaining signal integrity in dense wavelength-division multiplexing (DWDM) and erbium-doped fiber amplifier (EDFA) pump combiner applications. Its polarization-maintaining (PM) fiber design ensures that the linear polarization of input light is not degraded, a requirement for coherent communications and interferometric sensing systems.

The WDM typically uses thin-film filter (TFF) technology, which provides stable performance across a defined operating temperature range, often -5 to +70 degrees Celsius for industrial-grade units. Common specifications for such a component include an insertion loss of less than 0.8 dB, polarization-dependent loss (PDL) under 0.2 dB, and channel isolation exceeding 25 dB. The device is housed in a compact, ruggedized package, often with bare fiber or FC/APC connectorized pigtails, and is designed for integration into optical line terminals, test equipment, and fiber laser systems where precise wavelength management is necessary.

Buyers of this component include telecom equipment manufacturers, fiber laser producers, and research institutions requiring reliable pump-signal combiners for EDFA stages or wavelength-selective routing in sensor networks. Ruik-Tech Communication Co.,LTD., based in Dongguan, China, lists this product with flexible MOQ and competitive pricing, though exact figures and lead times should be confirmed directly with the supplier. The listing notes availability of ISO certifications and trade terms such as CIF and FOB, which buyers should verify during inquiry to ensure compliance with their import and quality assurance requirements.

Ruik-Tech Communication Co.,LTD. is a supplier of optical communication components based in Dongguan, Guangdong, China. The company's registered address places it at Floor 4, Building A, Zhaohe Industrial Park in the Eastern City District of Dongguan. The listing indicates a 'harbor' trust tier on the platform, but the supplier's response rate is currently listed as 0.00%, meaning no average response time is available. This suggests potential buyers should allow for variable communication timelines when initiating contact.

The company's product listing focuses on passive optical components, specifically wavelength division multiplexers. The description provided is generic and does not detail Ruik-Tech's specific manufacturing capabilities, years in operation, or client portfolio. While the listing mentions ISO certifications and flexible trade terms, these are not substantiated with specific certificate numbers or documented MOQ/pricing structures within the available data. Buyers are advised to request detailed company profiles, verifiable certification documents, and direct quotes to assess the supplier's suitability for their procurement needs.
