Import Dfb Diodes — Buy in wholesale FOB from Supplier in China

DFB Diodes are distributed feedback semiconductor devices used to generate single‑mode optical signals for a variety of electronic systems. The supplier offers several variants, including solid‑state, tube, light‑emitting (LED) and light‑sensitive diodes, each tailored to specific circuit requirements. While the listing does not provide exact wavelength or power figures, typical DFB diodes operate around 1550 nm with output powers in the range of 5‑15 mW. The devices are built on a gallium arsenide (GaAs) substrate, which is standard for high‑frequency photonic components.

Typical performance metrics for DFB diodes include a threshold current of about 30 mA and a slope efficiency near 0.5 W/A, delivering stable single‑mode emission. The linewidth is generally around 10 MHz, and the polarization extinction ratio is commonly 15 dB, meeting the demands of telecom and sensing applications. The supplier indicates compliance with ISO and CE standards, suggesting adherence to recognised quality frameworks. Packaging options such as TO‑can and butterfly mounts are standard in the industry.

These diodes are commonly sourced by manufacturers of optical transceivers, automotive LiDAR modules, and renewable‑energy monitoring equipment. Buyers typically request FOB or CIF shipping and prefer payment via L/C or T/T, both of which the listing notes as available. The supplier’s response metrics show a 0 % response rate, so importers should establish contact channels early in the procurement process. Confirm any MOQ, lead‑time, and required documentation directly with A&S Semiconductor Co., Ltd.

A&S Semiconductor Co., Ltd. is situated at 10 West 2nd Street, Wuhou District, Chengdu 610041, Sichuan, China. The company is classified as an imported‑tier supplier and holds a harbour trust tier on the platform. Its public profile records a response rate of 0 % and no average response time, indicating that outreach may require direct contact. The firm’s core activity is the production and export of semiconductor components, including DFB diodes.

The listing supplies technical descriptions of the diode variants but does not disclose specific MOQ, lead‑time, or pricing, inviting buyers to request a quotation. ISO and CE certifications are mentioned, yet no supporting documents are attached. No details on production capacity or client references are provided. Prospective purchasers should ask for certification copies and any available test reports before committing to a contract.
