Import 1064nm 3poer Polarization Maintaining Circulator — Buy in Bulk from Supplier in China

This 1064nm 3-port polarization maintaining circulator from Ruik-Tech Communication Co., Ltd. is a passive optical component designed to route light signals between three fibre ports in a specific sequence. The device operates at a central wavelength of 1064nm, a band commonly associated with neodymium-doped solid-state lasers and certain fibre laser systems. Its polarization maintaining (PM) construction is critical for applications where the state of polarization must be preserved to avoid signal degradation or interference with downstream components.

The circulator's PM design typically utilises PANDA or bow-tie style stress rods within the fibre to maintain linear polarization alignment. Key performance parameters for this class of device include a typical insertion loss below 1.0 dB, isolation greater than 30 dB, and a return loss exceeding 50 dB. The component is housed in a compact, ruggedised package suitable for integration into benchtop instruments or OEM modules, with common fibre termination options being FC/APC or bare fibre pigtails. These specifications align with industry standards for telecom-grade passive optics, though exact figures for this unit should be confirmed with the supplier.

Primary buyers include engineers and system integrators working with fibre lasers, optical coherence tomography (OCT) systems, and quantum optics research setups. The 1064nm wavelength is prevalent in materials processing, medical laser delivery, and scientific instrumentation. Sourcing from Ruik-Tech Communication, a supplier based in Shenzhen, Guangdong, involves trade terms that are not specified in the listing; buyers should confirm minimum order quantities, lead times, and whether pricing is quoted on an EXW, FOB, or CIF basis directly with the company.

Ruik-Tech Communication Co., Ltd. is listed as a supplier of optical components with an address at 9F, Building A, Zhonghengsheng Technology, 3 Xinyu Road, Shajing Town, Baoan, Shenzhen 518104, Guangdong, China. The company's profile indicates it is an 'imported' tier entity on the platform, suggesting it may act as a distributor or agent for manufacturers. Its trust tier is classified as 'harbor', and its listed response rate is 0.00%, with an average response time of 0 hours, which means prospective buyers have no public data on communication reliability from this platform profile.

The listing does not provide details on the company's operational history, number of employees, specific manufacturing capabilities, or client portfolio. The product page attributes the circulator to Ruik-Tech but does not specify whether the company is the original equipment manufacturer (OEM) or a reseller. Buyers should verify the company's role, its quality management certifications (such as ISO 9001), and request documentation like test reports or compliance certificates directly before committing to an order. The physical address in Shenzhen places it within a major Chinese electronics and photonics manufacturing hub.
