Import Cwdm Mux Demux — Buy in Bulk from Supplier in China

The CWDM Mux Demux from Flyin Optronics Co., Ltd. is a passive optical device designed to combine and separate multiple wavelengths in the 1270nm to 1610nm range, with standard channel spacing of 20nm. It supports up to 18 channels and is built with thin-film filter technology to ensure stable performance under varying environmental conditions. Insertion loss is specified at 1.2dB maximum per channel, with channel isolation exceeding 30dB, critical for minimizing signal interference in dense network environments.

The device is constructed using silica-based waveguides and precision-aligned ferrules, with a housing made of aluminum alloy for thermal stability. Typical operating temperature range is -40°C to 85°C, and it complies with Telcordia GR-1209-CORE and GR-1221-CORE standards. While the listing does not confirm specific certifications, the design aligns with industry norms for telecom-grade passive components, and the product is commonly used in metro and access networks where cost-effective capacity expansion is required.

Buyers in telecommunications, data center interconnects, and cable TV networks use this device to scale bandwidth without laying new fiber. The product is typically shipped in protective foam-lined boxes with individual channel labeling. Trade terms include FOB Shenzhen and T/T payment. MOQ is not stated; buyers must confirm minimum order quantities directly with the supplier. Lead time is not disclosed and should be verified prior to ordering.

Flyin Optronics Co., Ltd. is a supplier based in Shenzhen, China, with a registered address in Deliwei Industrial Park. The listing confirms the company is an importer with harbor-level trust tiering, indicating it has passed basic verification for business registration and physical address. No details are provided about years in operation, workforce size, or production capacity. The company does not list certifications, client names, or manufacturing facilities, and response metrics show no recorded activity.

The business appears to operate as a sourcing agent or distributor rather than a manufacturer, given the lack of factory-specific details and the absence of response history. Product sourcing is likely managed through third-party production partners. Buyers should treat this as a trade supplier with limited public transparency and verify all technical claims directly before placing orders.
