Import Cwdm Mux/Demux Module — Buy in wholesale FOB from Supplier in China

The Flyin CWDM Mux/Demux Module is a passive optical device built using thin-film coating technology and non-flux metal bonding for micro-optics packaging. It supports channel spacing of 20 nm across configurations from 4 to 18 channels, with center wavelength accuracy of ±0.5 nm and a passband of ±7.5 nm at -0.5 dB. The device operates across wavelengths from 1270 nm to 1610 nm, with insertion loss ranging from 1.5 dB for 4-channel Mux to 3.5 dB for 16-channel Demux. It features epoxy-free optical paths and low temperature sensitivity, ensuring stable performance in variable environments.

The module is available with bare fiber, 900 µm loose tube, 2 mm cable, or 3 mm cable options, with standard fiber lengths of 1 m or 2 m. Connector options include FC/APC, FC/PC, SC/APC, SC/PC, ST, and LC, or none. Channel isolation exceeds 30 dB for adjacent channels and 40 dB for non-adjacent channels, meeting standard telecom requirements. The device is designed for applications requiring high channel density without active components, making it suitable for access networks and cellular backhaul where reliability and low maintenance are critical.

Buyers typically include telecom infrastructure providers, network integrators, and enterprise data center operators deploying CWDM systems in metro and access networks. The product is supplied in standard packaging with individual unit testing reports. Trade terms are negotiable, with bulk orders accepted. Lead time and packaging customization require direct confirmation with the supplier. No certifications are listed; buyers should request test reports for insertion loss and isolation per ITU-T G.694.2.

Flyin Optronics Co., Ltd operates from Deliwei Industrial Park in Longhua, Shenzhen, China. The listing confirms no public verification status beyond a harbor-tier trust rating and zero response rate. No company history, certifications, certifications, workforce size, or client list are disclosed. The supplier's technical focus is evident in the precision of the optical packaging design and specification documentation provided.

The supplier does not claim ISO, CE, or any other certification. There is no mention of production volume, export experience, or R&D capacity. Buyers should treat this as a technical manufacturer without public-facing business credentials. All claims about performance are derived solely from the product's technical data sheet. Verification of compliance with ITU-T G.694.2 must be requested directly.
