Import Bd-Mlt Uj-210s Writer — Buy in wholesale FOB from Supplier in China

The BD-MLT UJ-210S Writer is an industrial-grade optical disc drive manufactured by Guangzhou Guofeng Electronic Technology Co., Ltd., a supplier based in Tianhe District, Guangzhou, Guangdong Province. This device writes to Blu-ray Disc Multi-Layer (BD-MLT) media, supporting single-layer BD-R/RE at 25 GB and dual-layer at 50 GB, with the UJ-210S designation indicating a slimline 9.5 mm height form factor typical of notebook-integrated drives rather than standard desktop 5.25 inch units. The drive employs a Serial ATA (SATA) interface, the standard connection protocol for optical drives manufactured after 2007, replacing the older Parallel ATA ribbon cable standard.

The writer incorporates a blue-violet laser diode with a 405 nm wavelength, enabling the higher data density that Blu-ray format demands compared to DVD's 650 nm red laser or CD's 780 nm infrared laser. Error correction follows the standard Reed-Solomon product code specified in the Blu-ray Disc Read-Only Format and Blu-ray Disc Recordable Format system descriptions, with CIRC (Cross-Interleaved Reed-Solomon Coding) handling burst errors typical of optical media surface contamination. The mechanical chassis uses standard mounting points compatible with slimline optical drive bays in industrial computing enclosures, medical imaging equipment, and broadcast video hardware where internal disc authoring remains necessary.

Primary buyers include system integrators serving medical PACS (Picture Archiving and Communication Systems), broadcast ingest stations requiring local disc mastering, and industrial control system manufacturers needing offline firmware distribution. The SATA interface operates at 1.5 Gbit/s or 3.0 Gbit/s transfer rates, backward compatible with earlier SATA revisions. Packaging for optical drives typically involves anti-static foam cushioning within individual cartons, with master carton quantities of 20 to 50 units for distributor orders. Buyers should confirm with Guangzhou Guofeng Electronic Technology Co., Ltd. whether the supplied units include bezel faceplates, mounting hardware, and SATA data cables, as accessory inclusion varies by shipment batch.

Guangzhou Guofeng Electronic Technology Co., Ltd. operates from Room 1202, South Building, Tianshengming Garden, on West Shipai Road in Tianhe District, Guangzhou, Guangdong Province, postal code 510630. The company's registered address places it within Guangzhou's central technology corridor, a district dense with electronics trading firms and component distributors serving both domestic Chinese manufacturers and export markets. The supplier holds an imported tier classification and a harbor trust tier, which indicates a baseline verification level rather than premium supplier status; this distinction matters for buyers assessing risk, as harbor-tier suppliers typically undergo less frequent audit cycles than gold or verified-tier counterparts.

The listing reveals a response rate of 0.00 percent and an average response time of zero hours, which signals that either the supplier has not engaged with recent enquiries through the platform or the account lacks active inquiry management. Buyers should treat this as a significant due diligence flag and initiate direct contact through the provided address or alternative channels before committing to orders. The company profile does not disclose manufacturing certifications (ISO 9001, ISO 14001), export license numbers, or registered capital, and these gaps should be filled through direct verification rather than assumed. What the listing does confirm is the supplier's physical presence in a known electronics trading hub, which allows for potential factory audits or third-party inspection arrangements if order volumes justify the cost.
