About H-lin International Group Limited - Telecommunication Cables Supplier in Hong Kong

Hong Kong‑based H‑lin International Group Limited lists five active products in its catalogue. The company focuses on telecommunication cables, electronic connectors and related infrastructure equipment. Its product portfolio includes fiber optic patch cords, adapters and a media converter, all targeting network build‑out and data‑center interconnect projects. The active product count of five aligns with the three top categories reported.

The listed items are an armoured fiber optic patch cord, a standard fiber optic adapter, a fiber optic media converter, a 10 Gb/s fiber optic patch cord and a bare fiber adapter. These products fall under the telecommunication cable and connector HS‑code families that typically cover optical fibers and associated accessories. The catalogue does not provide HS codes, but the items are classified within the broader telecom infrastructure segment.

Product Range and Specialties of H-lin International Group Limited

The armoured and 10 Gb/s patch cords are usually produced with a steel strength‑member and a protective jacket, conforming to IEC 60793‑2‑40 for single‑mode fibers and IEC 60794‑1‑2 for multi‑mode fibers. Common grades include OS2 for single‑mode and OM3/OM4 for multi‑mode, with attenuation values under 0.35 dB/km for 10 Gb/s transmission. Connectors are typically LC or SC, with insertion loss under 0.3 dB and return loss better than - 55 dB.

Fiber optic adapters, both bare and with protective housings, are generally supplied in standard LC, SC or MPO formats and are tested for insertion loss and return loss per IEC 61754‑6. The media converter translates electrical Ethernet signals to optical wavelengths, often supporting 10/100/1000 Mbps or 10 Gb/s SFP modules and complying with IEEE 802.3 standards. Buyers usually request data sheets that list operating temperature ranges (‑40 °C to +85 °C) and power consumption.

Trade and Export Information - H-lin International Group Limited

Hong Kong serves as a major re‑export hub for optical networking components, with shipments frequently destined for Southeast Asia, the European Union and North America. Export logistics for fiber optic cables and accessories typically involve 20‑foot or 40‑foot containers packed on reels or in anti‑static boxes, using Incoterms such as FOB Hong Kong or CIF major ports.

Importers usually require compliance with international standards such as IEC 60794, ISO 9001 quality‑management, CE marking for the EU and RoHS for hazardous‑substance restrictions. Customs authorities often request test reports for attenuation, tensile strength and fire resistance, especially for armoured cables. Hong Kong’s free‑port status allows quick customs clearance provided documentation meets these regulatory expectations.

Sourcing from H-lin International Group Limited - Buyer Guidance

Prospective buyers should request product datasheets that detail fiber type (OS2, OM3, OM4), connector polishing type (UPC or APC), and mechanical specifications such as bend radius and jacket material. For media converters, buyers need to verify supported Ethernet standards, optical transceiver compatibility and Power‑over‑Ethernet options.

Prior to placing an order, it is advisable to obtain a sample for laboratory testing of insertion loss, return loss and environmental durability. Buyers should also ask for certificates of conformity (e.g., ISO 9001, CE) and a third‑party test report if the supplier does not hold them directly. Minimum order quantities and lead times are typically defined per product line and should be clarified in the quotation.

What product categories does H‑lin International Group Limited offer?

The supplier lists five items - armoured fiber optic patch cord, standard fiber optic adapter, fiber optic media converter, 10 Gb/s fiber optic patch cord and bare fiber adapter - all classified under telecommunication cables, electronic connectors and telecom infrastructure equipment.

Which connector types are available for the fiber optic adapters?

The catalogue mentions adapters that are commonly supplied in LC and SC formats, meeting IEC 61754‑6 specifications for insertion loss and return loss.

What standards should buyers verify for the patch cords?

Buyers should check compliance with IEC 60793‑2‑40 (single‑mode) or IEC 60794‑1‑2 (multi‑mode), and confirm attenuation below 0.35 dB/km for 10 Gb/s operation, as well as appropriate armouring and jacket ratings.

Are there typical certifications required for these products?

While the supplier’s certifications are not listed, importers normally request ISO 9001 quality‑management, CE marking for EU markets and RoHS compliance for electronic components.

What is the usual packaging for fiber optic cables from Hong Kong exporters?

Export packs are typically wound on reels or placed in anti‑static boxes, secured in standard 20 ft or 40 ft containers with moisture‑absorbing packs to protect optical performance.

What documentation is needed before shipment?

Common documents include a commercial invoice, packing list, certificate of origin, test reports for attenuation and fire resistance, and any requested conformity certificates.
