The GYTAH58 cable combines a fully stranded armored core with an integrated figure-8 messenger: loose tubes are stranded around a central strength member, wrapped in the 58 protection package and bonded to a steel messenger for self-supporting aerial installation.
The stranded core gives the bending and temperature stability of a GYTA-class build, while the 58 package and messenger push the tensile ratings to 1000/3000 N — the same figures as the heavy GYTA53 buried build, but in a cable that clamps straight onto poles.
GYTAH58 is the heavy option in this site’s figure-8 family: GYXTC8Y and GYTC8S cover light and medium spans, and GYTAH58 covers the aerial routes that also face crush, rodent or abrasion exposure. Bending radii of 15D/30D match the GYTA53 family.
Product Features
Integrated messenger — self-supporting figure-8 installation without a separate support strand.
Stranded core — loose tubes around a central member keep bending and temperature performance stable.
Heavy protection — 1000/3000 N tensile and crush margins for exposed aerial routes.
Rodent and abrasion resistance — the 58 protection package shields the core on difficult spans.
Water blocking — gel-filled tubes and interstices block longitudinal water ingress.
Counts to 96+ — covers aerial backbone sections, not just drop spans.
Typical Applications
Exposed aerial backbone sections between towns; pole lines that combine long spans with rodent or abrasion exposure; river-crossing approaches and railway corridors where a heavy, self-supporting build is specified; and upgrades of existing GYTC8S routes to a higher protection class.
Selection and ordering
Order by fiber count (4-96) and span class. Send the pole line data - span, height, ice and wind zone - so the messenger and core are matched; heavier messengers and double-sheath 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; GYTAH58 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.

GYTAH58 figure-8 stranded armored cable: 4-96 fibers, integrated messenger, 1000/3000 N, 15D/30D for aerial and buried-aggressive routes.
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.
