FIBCONET supplies bare optical fiber through deep inventory and authorized distribution partnerships with China’s four leading fiber makers — YOFC, ZTT, Hengtong and Fiberhome. Hengtong holds our largest stock position, and we also maintain cooperation with Far East and other tier-one suppliers.
For spot orders we can release approximately 100,000 cores every two weeks. Annual contracts above one million cores are welcome and priced on brand-linked futures basis. Every roll ships with an OTDR test report and factory inspection video; our Ningbo warehouse accepts on-site inspection at any time.
Beyond standard telecom bare fiber, FIBCONET manufactures drone fiber optic spools — internal-winding, external-winding, Kevlar-reinforced and underwater versions — used by FPV and industrial drone builders worldwide for tethered communication payload lines.

|---|---|---|---|
| Internal-Winding (glued) ABS housing, shaftless design |
nce 60 km per spool | 120 km/h average, 150 km/h peak | Aggressive flight profiles, long-range missions > 30 km, high anti-break requirement |
| External-Winding (glue-free) Fixed-shaft ABS spool |
nce 60 km per spool | Steady low-speed payout | Budget-sensitive bulk deployment, short-range low-speed missions |
| Kevlar-Reinforced Spool Kevlar composite yarn + cold-modified PVC jacket |
nce 30 km per spool, cable down to 0.3 hli txoj kab uas hla | 100–120 km/h regular, 170 km/h peak | Racing drones, high-speed pass-through scenarios, cold-climate operation |
| Underwater Spool Fiber + tight buffer + aramid yarn + PVC tsho, aluminium housing |

Underwater spools feature a proprietary pressure-equalization vent that balances internal and external water pressure, preventing housing deformation at depth. Aramid yarn reinforcement delivers 200 N tensile strength, protecting against marine life impact and pressure-driven fiber breakage.
Bare optical fiber is the raw waveguide — core + cladding + acrylate coating — before it becomes a finished optical cable. It ships on 50.4 km standard reels, Nrog 40.8 km, 60.4 km thiab km 100 km reel lengths available on request. If your process can accept non-standard reel lengths in the 20–40 km range, we can offer a more cost-efficient stock structure priced up to 20% lower.

| Zoo tshaj rau | Long-haul backbone, straight runs | FTTH, poob cable, drone reels, tight housings | Extreme bending, invisible cable, high-density DCI |
G.654.E has a larger effective area than G.652.D, which lowers non-linear impairment on high-capacity coherent transmission links. It is the fiber of choice for terrestrial 400G / 800G backbone links and terrestrial extensions of submarine networks. Tensile strength is 60 N txheem. Our current G.654.E output is around 100,000 km per month across authorized brands.

A note on our supply model. FIBCONET is an authorized distributor for the four leading Chinese fiber makers (YOFC, ZTT, Hengtong, Fiberhome), not a bare-fiber preform manufacturer. Our in-house manufacturing capability focuses on optical cables, PLC splitters, and drone fiber spools. This structure gives you branded fiber quality with the pricing leverage of consolidated purchasing.
Our Ningbo warehouse consolidates spot stock from YOFC, ZTT, Hengtong and Fiberhome, with Hengtong as the largest single position. This lets us quote spot on nearly any mainstream single-mode or multimode grade without waiting for factory production cycles.
Drone spools are manufactured in-house on dedicated lines. Monthly capacity for the popular 20 km external-winding spool reaches kwv yees 7,000 chav nyob. Long-range internal-winding spools use a proprietary two-component adhesive system that cures immediately after fiber termination — eliminating the 24-hour rest period and the layer-adhesion issues common with ordinary adhesives.
For standard 50.4 km reels we optimize palletized shipping for air freight:
Drone spools xa hauv lub thawv tiv thaiv ib leeg; Cov lej thawv txawv raws li qhov loj ntawm spool thiab tau lees paub thaum txiav txim.
FIBCONET muaj kev paub ntau nrog DDP cov lus mus rau Europe (Poland, Bulgaria, Germany thiab lwm qhov chaw EU). Peb tus nqi thauj khoom sib tw; Hu rau cov muag khoom kom tau txais nqi nce av rau koj chaw nres nkoj mus txog.
