The GCYFY air-blown micro optical cable uses non-metallic strength members without armor: 250 µm fibers sit in jelly-filled loose tubes stranded around a non-metallic central member inside a small, lightweight, low-friction sheath.
Installation is by blowing: micro ducts are pulled or blown into existing protective pipes, then the micro cable is blown into the micro ducts. This overcomes the limits of conventional duct installation, improves duct utilization and lets capacity grow in stages — blow additional cable as traffic grows instead of pulling one large cable up front.
GCYFY is aimed at congested metro ducts where destructive excavation is impossible, and at backbone, metro and access rings where staged upgrades matter. Because the cable is all-dielectric there is no grounding requirement, and low-friction design supports blowing distances of 1200 m and beyond.
Product Features
Air-blown installation — blown into pre-installed micro ducts; no pulling tension on the fibers.
Staged capacity — blow in more cable as traffic grows, reducing upfront investment.
Future upgrades — micro cable can be blown out and replaced without touching the duct infrastructure.
All-dielectric — no grounding required; low-friction sheath enables long blowing distances.
Duct utilization — makes full use of existing protective pipes in congested metro ducts.
Branching on demand — outer tube and micro ducts can be cut anywhere without affecting other cables.
Typical Applications
Metro and backbone duct upgrades in congested city centers; staged capacity rollouts where traffic grows year by year; data-center campus links between buildings through existing conduit; and any route where blowing avoids excavation permits and road closures.
Selection and ordering
Order by fiber count (24-288), micro duct size and blowing plan. Send the duct map, route length and bend schedule so we can size the micro ducts and quote blower time; OM3/OM4 and G.657 fiber options are available on request.
Packaging, delivery and support
Cables are supplied on standard wooden reels (2530, 4056 or 610 types) with embossed meter marks every meter and desiccant-packed ends; GCYFY reel lengths follow the quotation and can be split to match splice-point spacing. Every reel ships with a factory test report covering attenuation, OTDR traces and geometric checks. As a Dongguan factory with 20,000+ m2 of production space we support OEM and ODM branding, neutral packaging, third-party inspection before loading, and consolidation with the patch cords, splitters and ODF hardware on this site in one container. Sample lengths are available for qualification, and our engineers review pulling plans, splice schedules and closure layouts free of charge before dispatch. Typical lead time is two to three weeks for standard builds and four to five weeks for span-engineered or OEM-branded orders, with photos and loading records sent before every container leaves the factory.

GCYFY air-blown micro cable: 24-288 fibers blown into micro ducts, all-dielectric, 4.5-9.3 mm, blowing distances over 1200 m for metro upgrades.
Yes. Huifiber supplies cable under the buyer's own brand as well as under the Huifiber brand. Fibre count, jacket material, jacket print, drum marking, drum length, packaging and datasheet layout can all be produced to the customer's requirement, and the engineering team can work from a customer specification or adapt an existing construction to a new route requirement.
Every production batch is tested before it leaves the plant in Dongguan. Attenuation and geometry are measured on OTDR and optical bench equipment, and mechanical performance is verified against the datasheet for the construction. A factory test report is issued with each shipment, so an incoming inspection can be checked against the same numbers.
Send the fibre count and fibre type, the jacket material or fire rating, the route length or span and the drum length you need, the destination port or country, and any certification or test-report requirement. With those details the sales engineer can confirm the construction and return a quotation with an indicative lead time.
