Import Bare Fiber Adapter — Buy in Bulk from Supplier in Hong Kong

The bare fiber adapter from H-lin International Group Limited is a connectivity component designed for temporary or field-terminated fiber optic connections where a standard connectorised patch cord is not yet available. It accepts un-terminated bare fiber and aligns it to mate with standard connector interfaces such as SC, FC, ST, or LC, depending on the variant. The adapter body is typically precision-machined metal or engineered polymer housing with a ceramic or bronze alignment sleeve. H-lin International Group Limited sources from Hong Kong, a major hub for fiber optic component trade, though the listing does not specify the exact sleeve material or connector compatibility of this unit.

Bare fiber adapters generally accommodate standard cladding diameters of 125 µm with buffer diameters from 250 µm to 900 µm, though buyers should confirm the exact fiber and buffer size range with H-lin International Group Limited. The alignment sleeve tolerance is critical, with typical ceramic sleeves offering concentricity within 1.0 µm and bore diameters of 126.0 to 126.5 µm for single-mode applications. Some variants include a built-in fiber stop or depth gauge to control insertion depth and prevent damage to the mating connector ferrule. The adapter may feature a screw, push-pull, or bayonet coupling mechanism corresponding to the target connector standard. For multimode fibers, the same mechanical principles apply but with slightly relaxed concentricity tolerances of 2.0 to 3.0 µm.

These adapters are used by telecommunications contractors, data center installers, and network maintenance teams for temporary testing, troubleshooting, and emergency restoration of fiber links. They are also employed in laboratory environments and during cable assembly manufacturing for quick verification of fiber continuity and loss. Buyers importing from H-lin International Group Limited in Hong Kong should confirm the specific connector interface, fiber mode compatibility, and whether the adapter includes a fiber clamp or requires external fiber holding. The supplier's response rate is not recorded, so direct enquiry is necessary to establish communication reliability, sample availability, and any minimum order requirements.

H-lin International Group Limited is registered at Ngau Tau Kok Siu King Building, 6 On Wah Street, Kowloon, Hong Kong. The company operates as an imported-tier supplier within the harbor trust tier classification. No response rate data is available for this supplier, and the average response time is recorded as zero hours, which indicates that engagement metrics have not been established or tracked. The supplier profile does not disclose years in operation, factory ownership, headcount, or revenue figures.

The listing presents H-lin International Group Limited as offering bare fiber adapters for bulk supply, though it does not specify manufacturing origin, whether products are stocked in Hong Kong, or shipped from elsewhere in the region. There is no stated certification, quality management system, or factory audit information. Buyers should treat the supplier as a trading entity based on available information and conduct standard due diligence including sample evaluation and verification of product specifications before committing to volume orders.
