About General Components Inc - Telecommunication Cables Supplier in China

China‑based General Components Inc lists five active optical‑fiber products. The catalogue includes a Sc/sc optic fiber patch cord duplex multimode, an E2000 optic fiber patch cord singlemode simplex, an FC fiber adaptor, an LC attenuator and a GYXTW fiber optic cable. All items fall under the broader headings of telecommunication cables, electronic connectors and telecommunication infrastructure equipment as indicated in the supplier’s top categories. The product titles identify the connector types (FC, LC) and the cable formats (patch cord, bulk cable). The listing does not provide HS codes, so classification must follow the standard telecom‑equipment headings used for fiber optics.

Product Range and Specialties of General Components Inc

The five listed items cover standard fiber‑optic interconnects used in telecom and data‑center networks. Multimode duplex patch cords are typically supplied in OM3 or OM4 grades with a core diameter of 50 µm and a typical attenuation of ≤3.5 dB/km at 850 nm, while singlemode simplex cords follow OS2 specifications with ≤0.35 dB/km at 1310 nm. FC adapters and LC attenuators are generally built to IEC 61754 standards, offering insertion loss below 0.2 dB and return loss better than 55 dB. Bulk fiber optic cable such as the GYXTW model is commonly jacketed with LSZH or PVC sheathing, supplied in reels of 500 m to 1 km, and meets IEC 61753‑1 loss class A. Buyers usually expect product data sheets that list wavelength range, connector polishing type (PC, APC) and mechanical dimensions.

Trade and Export Information - General Components Inc

China is one of the world’s largest exporters of fiber‑optic components, shipping mainly to Asia‑Pacific, Europe and North America. Products like patch cords, adapters and attenuators are classified under HS Chapter 85 (telecommunications equipment) and Chapter 90 (optical fibers) for customs purposes. Importers typically require compliance with IEC 61753 (optical fiber loss) and IEC 61754 (connector specifications), as well as RoHS and CE marking for equipment destined for the EU. Standard export packaging uses 20‑ft or 40‑ft containers with reels or boxed units, and Incoterms such as FOB Shanghai or CIF Hong Kong are common. Export documentation frequently includes a Certificate of Origin, test reports, and a declaration of conformity to the relevant IEC standards.

Sourcing from General Components Inc - Buyer Guidance

When sourcing from General Components Inc, request up‑to‑date test reports that cover insertion loss, return loss and OTDR trace data for each fiber type. Verify that the supplied specifications match the industry grades (OM3/OM4 for multimode, OS2 for singlemode) and that connectors conform to IEC 61754. Ask for a copy of the supplier’s ISO 9001 quality‑management certificate or any other compliance documents they can provide, and confirm RoHS/CE compliance if the goods are destined for Europe. Clarify packaging details - reel length, protective outer jackets and moisture‑barrier bags - and agree on MOQ, which for bulk cable is often a full reel, while patch cords may be ordered in cartons of 100 units. Lead times for fiber‑optic components from China typically range from 30 to 45 days after order confirmation, depending on volume and any custom testing requirements.

What wavelengths are supported by the Sc/sc optic fiber patch cord duplex multimode?

The duplex multimode patch cord is normally specified for 850 nm and 1300 nm transmission, matching the OM3/OM4 standards used in LAN and data‑center applications.

Does the E2000 singlemode simplex patch cord include APC or PC polishing?

E2000 singlemode cords are usually supplied with PC‑polished connectors unless the buyer requests APC, which provides a typical return loss of ≥55 dB at 1310 nm.

What loss values should be expected for the FC fiber adaptor?

FC adapters generally exhibit insertion loss below 0.2 dB and return loss better than 55 dB when tested according to IEC 61754‑5.

Are the LC attenuators calibrated for a specific attenuation level?

LC attenuators are offered in standard steps of 1 dB, 2 dB and 5 dB, each verified to ±0.1 dB accuracy under IEC 61754 testing.

What is the typical reel size for the GYXTW fiber optic cable?

The GYXTW cable is supplied on reels ranging from 500 m to 1 km, with outer diameters between 100 mm and 150 mm, depending on jacket type.

Which certifications should a buyer request before purchasing?

Buyers should request the supplier’s ISO 9001 certificate, IEC 61753 loss‑class test report, and RoHS compliance declaration, especially for shipments to EU markets.

What are the common Incoterms used for shipping these products from China?

FOB Shanghai and CIF Hong Kong are the most frequently used Incoterms for fiber‑optic components exported from China.

What packaging format is used for small‑quantity patch cords?

Patch cords are typically packed in anti‑static boxes of 100 units, each box sealed with moisture‑absorbing desiccant and a tamper‑evident label.
