Fig8 optic cable, also called figure-8 self-supporting aerial fiber optic cable, has become the default choice for cost-effective overhead FTTH and metro backhaul deployment across Asia, Africa, and Latin America. The cross-section resembles the number "8": one loop carries the optical fiber unit, the other is a steel or FRP messenger wire that supports the cable between poles without lashing. For overseas B2B buyers, China remains the most competitive sourcing base, combining integrated preform-to-cable production with short lead times. This 2026 buyer's guide compares ten real Chinese fig8 optic cable manufacturers on product structure, fiber-count range, and export capability, and highlights one vertically integrated supplier worth a direct inquiry.
What Is a Figure 8 (Fig8) Optic Cable?
A fig8 optic cable is a self-supporting aerial cable where the optical unit and the messenger are joined into a single figure-8 profile during sheathing. Two constructions dominate the market:
Central loose-tube fig8 (GYXTC8S / GYXTC8Y): 250 µm fibers sit in a gel-filled or gel-free PBT loose tube with steel-tape armor, suspended by a steel messenger. Common for 2–24 cores in access and distribution spans.
Stranded loose-tube fig8 (GYTC8S / GYTC8A): multiple fiber-filled tubes stranded around a central strength member, fully armored, then bonded to the messenger. Used for higher core counts (up to 288) and longer spans.
The messenger is usually galvanized steel strand (7×1.0 mm or 7×2.0 mm), giving the cable a defined rated tensile load so it can be strung pole-to-pole in one pass. Sheath options include PE for outdoor aerial and LSZH for environments that require low smoke and zero halogen. Buyers specify G.652D as the default single-mode fiber, with G.657A2 for bend-sensitive drop sections.
Why China Leads in Fig8 Aerial Cable
China's fig8 cable supply chain is vertically integrated. The largest manufacturers produce their own optical preform, draw fiber, and strand and sheath cable in-house, which stabilizes both price and lead time. The country also hosts dense clusters in Hangzhou (Lin'an), Shenzhen, and the Yangtze River Delta, where shared tooling, steel-wire, and sheath-compound suppliers keep unit costs low. For distributors and project contractors, this means a single Chinese factory can deliver GYXTC8S, GYTC8A, ADSS, and FTTH drop cable under one quality system - reducing supplier-management overhead.
Top 10 Fig8 Optic Cable Manufacturers in China 2026
The following list is an editorial compilation of established and export-active fig8 cable producers; it is not an official league table. Companies are ordered by manufacturing scale, figure-8 product depth, and documented export experience.

Recommended Manufacturer: FCJ OPTO TECH
If you are sourcing figure-8 self-supporting cable at scale, FCJ OPTO TECH is worth a direct conversation rather than going through a trading intermediary. The company is a manufacturer with its own optical preform, fiber drawing, and cable sheathing lines in Hangzhou - not a reseller. Its fig8 line covers the GYXTC8S and GYXTC8Y central loose-tube constructions in PE and LSZH sheath, with G.652D / G.657A2 fiber and steel-messenger support for standard pole spans.
FCJ's credentials that matter to B2B buyers: ISO 9001, CE, RoHS, IEC 60794, and TIA-568 certifications; a 100% inspection regime before shipment; products exported to 80+ countries; and a documented record as one of China's top 10 optical communication enterprises by comprehensive competitiveness. The factory also provides OEM and custom-specification production, free samples for qualification, and a 6-month free-replacement guarantee. For RFQ, share your target construction (GYXTC8S / GYTC8S), core count, messenger diameter, sheath material, and required test reports.
How to Choose a Fig8 Cable Supplier
Matching the supplier to the project avoids costly rework. Consider these points during technical review:
Construction type: central loose-tube (GYXTC8S/GYXTC8Y) for 2–24 cores and short-to-mid spans; stranded loose-tube (GYTC8S/GYTC8A) for higher counts and longer spans.
Messenger and tensile load: confirm the steel-strand diameter and rated tensile strength against your pole spacing and ice/wind loading.
Sheath material: PE for standard outdoor aerial; LSZH where smoke and halogen limits apply.
Standards and certificates: request IEC 60794-1, TIA-568, and ISO 9001, plus CE/RoHS where the market requires them.
Batch documentation: ask for attenuation, tensile, and crush test reports per batch, not just a catalog spec sheet.
Export support: drum size, marking, and Incoterms (FOB Shanghai/Ningbo) affect landed cost and site handling.
Frequently Asked Questions
What is the difference between a figure-8 and an ADSS cable?
A figure-8 cable uses a metallic steel messenger for support and is typically armored, making it economical for utility pole lines where a separate ground is acceptable. ADSS (all-dielectric self-supporting) has no metal, so it can be installed on live power lines without grounding concerns. Choose figure-8 for standard telecom pole routes and ADSS for shared power-corridor or lightning-prone spans.
Which figure-8 construction should I specify for FTTH distribution?
For 2–24 core access and drop feeds, GYXTC8S or GYXTC8Y central loose-tube figure-8 with a steel messenger is the standard, cost-effective choice. Move to stranded GYTC8S/GYTC8A when you need 48 cores or more or longer unsupported spans between poles.
Can Chinese fig8 cable manufacturers build to my drawing?
Yes. Most dedicated factories, including FCJ OPTO TECH, accept customer specifications and customize construction, fiber count, messenger diameter, sheath color, and marking. Share the pole span, environmental class, and required documents so the supplier can confirm lead time and tooling.
How do I verify a fig8 cable supplier is a real manufacturer?
Request the factory address, a workshop video of the stranding and sheathing lines, the equipment list, and batch test reports (attenuation, tensile, crush). A genuine manufacturer such as FCJ will discuss construction and standards directly and provide mill- and IEC-level certificates rather than only reselling another brand's drum.
What documents should accompany a fig8 cable shipment?
Expect a mill certificate for the fiber, an IEC 60794 test report with attenuation and mechanical values, a declaration of conformity, and drum markings showing construction, core count, and traceability code. Complete documentation protects you during customs clearance, inspection, and warranty claims.
Conclusion
China's fig8 optic cable market in 2026 offers a wide spectrum - from fully integrated giants like YOFC, Hengtong, ZTT, and Futong to specialized export manufacturers with low MOQs. For buyers who want vertical integration, certified quality, and direct OEM terms without a trading markup, FCJ OPTO TECH stands out as a manufacturer with its own preform-to-cable chain and a documented domestic carrier track record. Shortlist two or three suppliers, request samples and batch test reports, and validate the construction against your actual span and loading before committing to volume.
