Import 1550nm High Power Pm Fused Coupler — Buy in wholesale FOB from Supplier in China

This 1550nm High Power PM Fused Coupler from Ruik-tech Communication (Dongguang) Co., Ltd. is a polarisation-maintaining fibre optic component designed for signal splitting and combining at the 1550nm wavelength, with a rated power handling capacity of up to 20W. The fused-type construction is specified for low insertion loss and stable, reliable performance in demanding optical environments. It is engineered for applications including fibre gyroscopes, power monitoring systems, and optical sensor networks where signal integrity is critical.

The coupler uses polarisation-maintaining (PM) fibre, which preserves the polarisation state of light passing through it, a requirement for coherent optical systems. Typical PM fibre types for 1550nm operation include PANDA and bow-tie designs, with standard cladding diameters of 125 micrometres and coating diameters around 250 micrometres. Fused biconical taper (FBT) technology is the standard manufacturing method for this class of coupler, offering a balance of performance and cost for power levels up to approximately 20W. Splitting ratios commonly available in the market range from 1:99 to 50:50, though the specific ratios offered by this supplier should be confirmed directly.

Buyers of this component typically include manufacturers of fibre optic gyroscopes for navigation and aerospace systems, designers of optical power monitoring equipment, and developers of distributed optical sensor arrays. The product is sourced from Dongguan, Guangdong, a major hub for photonics and electronics manufacturing in southern China. For procurement, buyers should verify the exact splitting ratio, connector type (such as FC/APC or FC/PC), fibre type, and lead time with Ruik-tech Communication, as these details are not specified in the listing and are critical for system integration.

Ruik-tech Communication (Dongguang) Co., Ltd. is a manufacturer based at 4/F, Bldg A, #39 Cixia Ind. 1st Rd., Wentang Community, Dongguan 523121, Guangdong, China. The company specialises in fibre optic components, as indicated by this fused coupler listing. The supplier is listed on the platform with a 'harbor' trust tier, which relates to platform verification status, though the response rate and average response hours are currently recorded as zero.

The listing does not provide details on the company's founding year, production capacity, employee count, or specific certifications. Buyers should request this information directly from Ruik-tech Communication to assess manufacturing scale and quality management systems. The product description focuses on technical performance for applications like fibre gyroscopes and optical sensors, suggesting a focus on the telecommunications and industrial photonics sectors. Verifying the supplier's export experience and sample availability is recommended before placing a bulk order.
