Choosing fiber optic cable manufacturers in China starts with identifying the legal supplier and the cable construction required by the project. An industry award list can identify names to investigate, but it cannot establish which factory will make the order.
Use the 2026 China optical-fibre-and-cable competitiveness list as a starting point, then verify the contracting entity, product construction and order-specific evidence. A China award category is not a global ranking, and an award is not a finished-cable qualification.
Use the profiles to narrow the supplier list, then compare drawings, samples and acceptance criteria for the actual cable order. The report-based business descriptions refer to 1 January–30 June 2026, not full-year 2026 results.
The 2026 China Optical Fibre and Cable Company List
The award reference is labelled China’s Top 10 Most Competitive Optical Fibre and Cable Enterprises for 2026, the twentieth edition. The ten names below follow its displayed order; they are not a separate HONGKAI scorecard.

Keep this China optical-fibre-and-cable category separate from global or broader optical-communications awards. The listed English names are useful identifiers; confirm the registered contracting name on the quotation and supplier documents.
An award entry does not establish factory capacity, delivery performance or suitability for a particular cable order. Start with the required cable construction and identify which legal entity and manufacturing site will fulfil the contract.
Company Profiles and Cable Procurement Checks
Use each profile to connect the company name, website and cable product family behind an offer. Website banners identify the brand; product illustrations help locate the relevant catalogue. Neither replaces a construction drawing, a dated quotation or batch test records for the cable being purchased.
യാങ്സി ഒപ്റ്റിക്കൽ ഫൈബർ ആൻഡ് കേബിൾ ജോയിന്റ് സ്റ്റോക്ക് ലിമിറ്റഡ് കമ്പനി (YOFC)

YOFC brand and optical-communications imagery.
- Reporting entity: YOFC and its subsidiaries, based in Wuhan, Hubei.
- 2026 reference period: Six months ended 30 June 2026.
- Dated workforce disclosure: Approximately 11,601 full-time employees at 30 June 2026, across the Company and its subsidiaries.
- Website: YOFC company profile.
The interim results describe optical fibre preforms, fibres, fibre cables, optical components and modules, and related products and services. Buying finished cable is a different scope from buying fibre or preforms. The group-wide headcount is not the workforce of one cable factory and does not establish its available output.
ഹെങ്ടോങ് ഒപ്റ്റിക്-ഇലക്ട്രിക് കമ്പനി, ലിമിറ്റഡ്.

Hengtong Group and its listed companies.
- Reporting entity: Hengtong Optic-Electric, Shanghai stock code 600487, based in Suzhou, Jiangsu; distinct from Hengtong Group.
- 2026 reference period: 1 January–30 June 2026.
- Website: Hengtong Group listed-company overview.
The interim report describes communications-network and energy-interconnection businesses. Its optical-communications scope includes the preform–fibre–cable chain and optical components. Broader energy or marine activities should not be treated as evidence for an ordinary optical-cable quotation. Confirm the actual product business and manufacturing site behind the offer.
ഫൈബർഹോം ടെലികമ്മ്യൂണിക്കേഷൻ ടെക്നോളജീസ് കോ., ലിമിറ്റഡ്.

FiberHome international brand imagery.
- Reporting entity: FiberHome Telecommunication Technologies, Shanghai stock code 600498, based in Wuhan, Hubei.
- 2026 reference period: 1 January–30 June 2026.
- Website: FiberHome international site.
The interim report places optical fibre and cable activities within a wider ICT business. It discusses optical preform and fibre manufacturing and developments in high-density optical cables and hollow-core fibre. These reported activities are not confirmation that a particular construction is commercially available for your order. Identify the cable-producing subsidiary, site and current datasheet separately.
ജിയാങ്സു സോങ്ഷ്യൻ ടെക്നോളജി കമ്പനി ലിമിറ്റഡ് (ZTT)

ZTT’s corporate sustainability banner concerns the company, not qualification of a particular cable construction.
- Reporting entity: Jiangsu Zhongtian Technology, Shanghai stock code 600522, based in Nantong, Jiangsu.
- 2026 reference period: 1 January–30 June 2026.
- Website: ZTT English website.
ZTT reports information-communications and energy-interconnection activities. Its optical scope includes preforms, fibres and cables, with specialty-fibre, high-density-cable and submarine-communications activities discussed alongside broader businesses. An enquiry for finished optical cable should therefore specify the cable family rather than refer to ZTT’s entire communications or energy portfolio.

ZTT optical cable illustrations help narrow the enquiry to a specific construction.
Use the optical cable range to identify the relevant product, then request the current datasheet and proposed manufacturing site. Corporate sustainability messaging and the award-list entry are separate from the cable’s test and acceptance requirements.
ജiangsu എറ്റേൺ കമ്പനി, ലിമിറ്റഡ്.

The English communications banner belongs to Jiangsu Etern Co., Ltd.; the wider Etern Group is a separate reporting scope.
- Reporting entity: Jiangsu Etern, Shanghai stock code 600105, based in Suzhou, Jiangsu; not interchangeable with the wider Etern Group.
- 2026 reference period: 1 January–30 June 2026.
- Website: Etern English site.
Etern’s interim report describes a preform–fibre–cable chain extending into specialty fibres, optical components and network-related activities. The disclosed cable range includes communications, specialty, indoor, drop and hybrid cables. Other businesses include wiring harnesses and power-related products or engineering.
For an optical-cable enquiry, identify the required cable family and the responsible manufacturing subsidiary. A preform, fibre or optical-module business is not the same supply scope as the finished cable on the purchase order. Use that subsidiary’s current drawing and datasheet to compare the offer.
ടോംഗ്ഡിംഗ് ഇന്റർകണക്ഷൻ ഇൻഫർമേഷൻ കോ., ലിമിറ്റഡ്.

Tongding’s official English homepage with the Connecting Horizons banner.
- Reporting entity: Tongding Interconnection Information, Shenzhen stock code 002491, based in Suzhou, Jiangsu.
- 2026 reference period: 1 January–30 June 2026.
- Website: Tongding optical cable catalogue.
The interim report identifies optical/electrical communications and security businesses. The reported product range includes optical preforms, fibres, optical cables, communications cables, railway-signal cables and power cables. This is a wider reporting scope than finished optical cable alone; ask for product-specific documents rather than relying on a corporate description.
Shenzhen SDG Information Co., Ltd. (SDGI)

SDGI’s English optical-communications banner identifies Shenzhen SDG Information Co., Ltd.
- Reporting entity: Shenzhen SDG Information, Shenzhen stock code 000070, based in Shenzhen, Guangdong.
- 2026 reference period: 1 January–30 June 2026.
- Website: SDGI English website.
The interim report separates cable activities from smart services, convergence businesses and property/asset operations. The cable scope includes optical fibres, optical cables, connectors, distribution products and data cables, alongside conductor-related products.
SDGI’s English catalogue distinguishes outdoor, indoor and power-system optical cables from single-mode fibre and optical components. State which product family is required before comparing an offer. Request the construction datasheet, installation requirements and batch tests for that cable, together with the operating entity that will manufacture it.
Tongguang Group Co., Ltd.

Communications-category imagery on the listed Tongguang cable company’s website; this is not a finished-cable construction drawing.
Website: Listed Tongguang cable company website.
The linked website identifies the listed cable company, stock code 300265, and separates optical-fibre/cable, power-transmission and equipment-cable activities. Keep this listed entity distinct from Tongguang Group when recording the supplier and comparing company figures. For an optical-cable order, select the optical range rather than relying on the broader power or equipment-cable portfolio.

GYTA cable cross-section for the listed Tongguang cable company.
ദി GYTA product page is a specific cable reference, not a description of every Tongguang product. Compare its construction with the project’s fibre count, sheath and installation requirements, then obtain the proposed seller’s current drawing and acceptance criteria.
Jiangsu Nanfang Communication Technology Co., Ltd.

An optical-cable illustration from Nanfang’s group product catalogue.
Website: Nanfang group English website.
The group website displays stock code 1617.HK and names Jiangsu Nanfang Communication Technology Co., Ltd. among its companies. The group website is therefore a useful route to the operating company, but holding-company figures should not be presented as that cable factory’s own figures.
For finished-cable sourcing, start with the optical-cable product catalogue, not the homepage’s wider infrastructure imagery. Preserve Jiangsu Nanfang Communication Technology Co., Ltd. as the operating-company name on the supplier record, and request its current construction datasheets, proposed manufacturing site and test records.
Potel Cable Group Co., Ltd. (Putian Hanfei)

English detail from Potel Cable Group’s optical-communication homepage banner.
Website: Potel Cable Group English website.
Potel’s English website separates optical fibres, finished optical cables, optical connectivity, data cables and copper connectivity. For a finished optical-cable order, use the cable category and request the construction drawing, delivered length, packaging and batch test requirements. A fibre-production or connectivity product page is not a substitute for the specified cable.
Keep Potel Cable Group Co., Ltd. (Putian Hanfei) matched to the registered entity on the quotation. Similar renderings such as “Potevio”, “Putian” and “Potel” should not be merged without checking the legal name and the manufacturing responsibility for the order.
Comparing Suppliers for a 2026 Cable Order

YOFC interim reporting period: six months ended 30 June 2026.
Keep the Report Period With the Claim
Compare business scope and reporting period before comparing financial or workforce figures. The first seven rows summarise first-half 2026 disclosures. For Tongguang Group, Nanfang and Potel, obtain documents for the exact supplier entity before making a numerical comparison.
| Reporting entity | Evidence period | Relevant disclosed scope and buyer boundary |
|---|---|---|
| YOFC | Six months ended 30 June 2026 | Preforms, fibres, fibre cables and optical components; group scope is not a single factory |
| Hengtong Optic-Electric | 1 January–30 June 2026 | Optical-communications chain within communications and energy businesses; not the entire Hengtong Group |
| ഫൈബർഹോം | 1 January–30 June 2026 | Fibre/cable activities within a wider ICT business; confirm the cable-producing entity |
| ZTT | 1 January–30 June 2026 | Optical-communications products within broader communications/energy activities; verify the relevant site |
| നിത്യത | 1 January–30 June 2026 | Optical fibre/cable and related products within a broader listed-company portfolio |
| ടോംഗ്ഡിംഗ് | 1 January–30 June 2026 | Optical/electrical communications and security; not optical cable alone |
| SDGI | 1 January–30 June 2026 | Cable business alongside other operations; identify the responsible operating entity |
| Tongguang Group | Entity-specific documents required | Establish the exact group, contracting entity and manufacturing site before attaching listed-company data |
| Jiangsu Nanfang Communication Technology | Entity-specific documents required | Preserve the exact operating-company name; do not substitute a holding-company dataset |
| Potel Cable Group (Putian Hanfei) | Entity-specific documents required | Match Chinese and registered English entity names; do not infer capacity or certification |
Check the Supplier for the Actual Order
Use the profiles as a starting point, then check the evidence at the proposed order date:
- Match the legal names on the quotation, contract and supplier documents, and identify the actual manufacturing site.
- Request the latest applicable disclosure and current product documentation. Record both the document date and the underlying reporting period.
- Obtain a dated quotation for the specified construction, quantity, testing, delivery and warranty scope. An interim report does not establish present capacity or lead time.
- For Tongguang, Nanfang and Potel, obtain documents for the legal entity on the offer rather than filling gaps with another company’s figures.
Specify the Cable Before Comparing Offers
Start with the installation environment, fibre specification and count, cable construction, sheath, delivered length and packaging. A supplier-list entry does not establish that the quoted cable fits the project. The jelly-filled versus dry-core fibre cable comparison helps separate water-blocking options that must be stated in the enquiry.
Ask each candidate for evidence for the actual order:
- The legal supplier name, manufacturing site and responsibility for any subcontracted production.
- A current datasheet and drawing for the quoted construction, including agreed fibre and material requirements.
- Sample or qualification records linked to that construction, rather than an unrelated product or generic certificate.
- Test methods, acceptance limits and batch records to accompany delivery. The fibre optic cable testing guide separates the test task from a generic “tested” claim.
- Written quantity, delivery, payment, warranty and claims-handling terms for the exact contracting entity.
These are procurement checks, not claims that the companies above have already passed them. Price and capacity comparisons require current offers with the same construction and delivery scope. This guide does not assign star ratings or guarantee the cheapest or most reliable supplier.
Separate Finished-Cable Sourcing From Machinery Procurement
If the project is to build or expand a cable factory, a finished-cable manufacturer list is not an equipment configuration. The fibre optic cable production-line overview maps cable families to process routes and equipment considerations.
HONGKAI Cable Machinery is the publishing and machinery-supply/project-integration brand for this guide, not the manufacturer of the companies’ cables listed above. No partnership, agency appointment or authorization is implied by inclusion. Keep the finished-cable supplier, actual manufacturer, equipment provider and contracting party distinct in each project record.
