Import C-Cwdm — Buy in wholesale FOB from Supplier in China

The C‑CWDM module supplied by Qian Hua Electronic Technology Co. is a compact wavelength‑division multiplexing device built from silica‑based fiber‑optic glass, PCB composite circuitry and an aluminium housing. It is intended for single‑mode fibre applications and aggregates up to 18 channels across the standard CWDM spectral grid. The module delivers low insertion loss, typically ≤1 dB, and operates over a temperature span that is typical for industrial equipment, - 40 °C to +85 °C. Its design prioritises space‑efficiency, allowing installation in dense telecom racks or data‑centre chassis.

Silica glass provides the low attenuation core required for long‑haul transmission, while the PCB composite handles driver electronics and thermal management. The aluminium enclosure protects against mechanical stress and environmental exposure, meeting typical IP‑rated durability for indoor networking gear. Industry‑standard CWDM modules adopt a channel spacing of 20 nm and a wavelength range of 1270‑1610 nm, which this unit conforms to. Typical specifications also include a return loss of >55 dB and power consumption under 2 W.

Telecommunication operators, internet service providers and data‑centre operators use this module to expand bandwidth without laying new fibre. The product is supplied in standard export packaging suitable for FOB or CIF shipment from ports in China. Buyers should confirm the minimum order quantity and any required custom firmware directly with Qian Hua Electronic Technology Co. before finalising the contract. The module meets recognised standards such as IEC 61753‑1 and CE for safety and electromagnetic compatibility.
