About Hunan Guanglian Photoeletricity Technologies Co., Ltd - Optical Fiber & Cable Supplier in China

China‑based Hunan Guanglian Photoeletricity Technologies Co., Ltd lists 22 active products covering a spectrum of optical fiber and cable solutions. The catalogue includes various forms of optical ground wire (OPGW), loose‑tube single‑mode cables, tactical armored fiber lines, splice closures, and unrepeatered submarine cable. Each product falls under HS Chapter 85, which governs optical fiber cables and related conductors, and the supplier groups its items within the broader HS‑code families for fiber optic cable assemblies and aerial cable systems.

The listed items range from stranded OPGW and PBT loose‑tube OPGW to 12‑core, 24‑core, 36‑core and 48‑core fiber optic splice closures. Additional offerings include double‑layer aerial ADSS cable, all‑dielectric self‑supporting cable, colour‑stripe fiber cables, and uni‑tube light‑armoured cable. Core constructions feature central stainless‑steel tubes, central aluminium tubes, and loose‑tube designs, reflecting typical industry configurations for power‑line integration and telecom deployments.

Product Range and Specialties of Hunan Guanglian Photoeletricity Technologies Co., Ltd

The supplier’s catalogue contains both aerial and submarine fiber solutions. Stranded and PBT loose‑tube OPGW are standard aluminium‑conductor‑steel‑reinforced (ACSR) wires that embed single‑mode fibers, complying with IEC 60794‑1‑2 specifications and often rated for tensile strengths of 200‑250 MPa. All‑dry loose‑tube single‑mode cables usually meet ITU‑T G.652 or G.657 standards, with attenuation below 0.35 dB/km at 1310 nm and 1550 nm. Tactical fiber optic cables with helical armour are built to MIL‑STD‑810 environmental resistance, typically featuring a Kevlar‑reinforced sheath and a minimum 10 kV dielectric rating. Submarine optical fiber cables are generally armoured, water‑blocked, and conform to IEC 60794‑1‑3, with typical outer diameters of 30‑45 mm and operating depths up to 3000 m. Splice closures for 12, 24, 36 and 48 cores follow IEC 60794‑5‑1, offering IP‑68 sealing and a minimum bend radius of 30 mm.

Trade and Export Information - Hunan Guanglian Photoeletricity Technologies Co., Ltd

China is one of the world’s largest exporters of optical fiber cable, supplying Southeast Asian, African, European and Middle‑Eastern markets. HS 8544 10 covers optical fiber cables, while HS 8544 90 includes OPGW and related aerial cable assemblies. Importers commonly request IEC 60794 compliance, ISO 9001 quality‑management certification, and RoHS conformity for metal‑tape products. Standard export packaging uses 20‑ft or 40‑ft containers with cable spooled on wooden or steel drums, and shipping terms frequently employ FOB or CIF. Customs inspections often require test reports for attenuation, tensile strength, and outer‑diameter measurements, especially for submarine and OPGW products.

Sourcing from Hunan Guanglian Photoeletricity Technologies Co., Ltd - Buyer Guidance

When sourcing from this supplier, buyers should request the latest product data sheet that details core count, fiber type (SM‑SM, SM‑MM), attenuation, tensile strength, outer‑diameter, and any armour specifications. Verify IEC 60794 test certificates and, where required, ISO 9001 or RoHS declarations before contract finalisation. Typical minimum order quantities range from one 20‑ft container (approximately 2‑3 km of cable) to larger shipments, with lead times of 6‑8 weeks for standard configurations and longer for custom‑spec OPGW or submarine cable builds.

What types of optical fiber cables does Hunan Guanglian list in its catalogue?

The catalogue includes stranded OPGW, PBT loose‑tube OPGW, all‑dry loose‑tube single‑mode cable, tactical helical‑armoured cable, colour‑stripe fiber cable, uni‑tube light‑armoured cable, double‑layer ADSS cable, and unrepeatered submarine cable.

Are the OPGW products compliant with international standards?

The OPGW items are designed to meet IEC 60794‑1‑2 for optical ground wire and typically conform to the tensile‑strength and conductor‑size requirements of ACSR standards.

Which certifications should a buyer request for these fiber products?

Buyers should ask for IEC 60794 test reports, ISO 9001 quality‑management certification, and RoHS compliance certificates, especially for metal‑tape and armoured cable variants.

What is the usual packaging and shipping format for the listed cables?

Cables are normally spooled on wooden or steel drums and loaded into 20‑ft or 40‑ft containers. Shipping terms most often used are FOB or CIF, with the goods classified under HS 8544 10 or HS 8544 90.

What are typical minimum order quantities and lead times?

Standard products usually have a MOQ of one 20‑ft container (about 2‑3 km of cable). Lead time is typically 6‑8 weeks for off‑the‑shelf items and longer for custom‑spec OPGW or submarine cable orders.

How can a buyer verify the performance of the tactical fiber optic cable?

Buyers should request attenuation test results (≤0.35 dB/km at 1310 nm/1550 nm), tensile‑strength data (≥200 MPa), and environmental test reports that confirm compliance with MIL‑STD‑810.

What documentation is needed for customs clearance of submarine cable?

Customs usually require the commercial invoice, packing list, IEC 60794‑1‑3 test certificate, and a declaration of compliance with any applicable import regulations of the destination country.

Can samples be provided before a full order?

The supplier can supply a short length sample (typically 5‑10 m) of each cable type for laboratory testing, subject to a sample‑handling fee and a non‑disclosure agreement.
