4–144F Aerial Duct Fiber Optic Cable

Quick answer: what is this GYTA cable for?

The page covers a metallic-strength-member, loose-tube GYTA cable family for protected outdoor duct routes and, only when engineered with a separate support method, non-self-supporting aerial routes. The published working data includes G.652.D fiber, count-specific cable diameter and weight, optical characteristics, temperature ranges and drum dimensions. Mechanical load limits, the exact aluminum-laminate construction, model/SKU and standards declaration still require a controlled BWNFiber source.

Key features

• Fiber counts: 4F / 6F / 8F / 12F / 24F / 48F / 72F / 96F / 144F.
• Fiber type: G.652.D single-mode fiber.
• Cable design: stranded loose tubes with PBT tube material and tube-filling compound.
• Central strength member: steel wire.
• Water blocking: tube-filling compound and cable-core water-blocking jelly, according to the supplied working table.
• Outer sheath: black HDPE, nominal 1.6 mm thickness in the supplied working table.
• Approximate cable OD: 9.0–14.1 mm across the listed configuration groups.
• Approximate cable weight: 80–185 kg/km across the listed configuration groups.
• Aluminum-laminate layer: TBC — approved construction drawing or BOM required before publication.
• Mechanical and installation limits: TBC — configuration-specific tensile, crush, impact and bend data required.

Construction and material schedule

Configuration table

Keep every value in the same configuration column. Do not combine the OD, weight, tube count or central-member size from different rows.

Engineering gate: the source record is flagged for multi-column alignment review. Confirm the complete 4F/6F/8F/12F/24F mapping and every high-count row against the approved drawing/datasheet before CMS entry.

Optical characteristics

These are cable-fiber characteristics, not a complete installed-link loss budget. Splices, connectors, route length, bends and installation workmanship must be addressed in the project’s separate link design and acceptance plan.

Temperature ranges

Where this cable fits—and where it does not

How to select the correct configuration

1. Define the route. State duct/conduit, supported aerial, transition sections, exposure and access points.
2. Confirm the network role. Identify feeder, distribution, campus/backbone or another controlled role.
3. Select fiber grade and count. The current working page covers G.652.D and the listed 4–144F configurations. Do not substitute another fiber grade without a revised product document.
4. Check pathway fit. Match the configuration-specific OD to duct fill, cable entry, closure and handling space.
5. Approve mechanical limits. Obtain maximum installation/long-term tension, crush, impact and minimum bend radius for the exact build.
6. Define aerial support if applicable. State messenger/support system, span, sag, wind/ice conditions, hardware and design responsibility. Do not treat this cable as ADSS.
7. Lock the drum plan. Confirm total length, length per drum, tolerance, drum dimensions, gross weight and destination constraints.
8. Control the documents. Put the part number, drawing revision, datasheet revision, marking and accepted deviations into the quotation and purchase specification.

Packing and drum planning

The table below is a working source record and must be reconciled with the final quotation. It must not be converted into a universal drum-length promise.

Testing, inspection and document package

The supplied record does not contain an approved test plan or test report. Before a bulk-order release, request the documents that apply to the exact quoted configuration:

• controlled product datasheet and construction drawing;
• fiber and tube color code;
• dimensional and weight tolerances;
• configuration-specific attenuation and optical criteria;
• tensile, crush, impact and bend test method, condition and acceptance limit;
• temperature and water-blocking declaration/test evidence;
• sheath marking and length-marking sample;
• drum, packing and inspection plan;
• agreed sample, first-article or lot records where required.

Factory cable data does not replace installed-link acceptance. The project designer should separately define continuity, splice/connector loss, OTDR or insertion-loss method, wavelengths, directions, launch/receive setup, pass limits and record format for the completed route.

Is this GYTA cable self-supporting?

No self-supporting capability is established by the supplied record. Treat aerial use as non-self-supporting unless BWNFiber engineering supplies a configuration-specific design and approved support/span limits. For a cable that must support its own weight, review an ADSS or engineered messenger/figure-8 product.

Which fiber counts are covered?

The working source covers 4F, 6F, 8F, 12F, 24F, 48F, 72F, 96F and 144F G.652.D configurations. The exact tube count, cable OD, weight and central-member dimensions vary by configuration.

Can this cable be installed in a duct?

Duct/conduit is the primary intended route in this draft, but route approval still requires the exact duct size, pull length, pulling method, maximum pulling tension and minimum bend radius for the selected cable build.

Can it be installed directly in the ground?

Direct-burial suitability is not established by the supplied record. Do not infer burial approval from the word “outdoor,” a metallic strength member or an aluminum layer. Review a declared direct-burial construction and the project’s soil, water, mechanical and rodent conditions.

What is the difference between this cable and ADSS?

ADSS is all-dielectric and self-supporting for an engineered aerial span. This GYTA working design uses a steel central strength member and has no verified self-supporting rating in the supplied record. The installation method and electrical environment must be reviewed separately.

What is the difference between GYTA and GYTA53?

The family names indicate different protective constructions, but the exact layers and approved applications must be taken from each BWNFiber model’s controlled drawing. Do not use a 53-series direct-burial assumption for this GYTA page.

What attenuation values are listed?

The working record lists ≤0.36 dB/km at 1310 nm and ≤0.22 dB/km at 1550 nm for G.652.D fiber. These values require engineering/source confirmation and do not include splice, connector or installation loss.

How do I choose the cable diameter?

Select the fiber count first, then use the matching configuration column. Check the resulting OD against duct fill, entries, clamps/support hardware, closures and the approved bend radius. Do not substitute a tube or strength-member diameter for the overall cable diameter.

What temperature ranges are listed?

The working record lists −40°C to +70°C for operation, −40°C to +70°C for storage/transport, and −20°C to +60°C for installation. Confirm the exact model, test basis and handling document before approval.

What should be included in a quotation request?

Send the route, installation method, fiber grade/count, length, drum plan, mechanical/environmental requirements, cable marking, quantity, destination, schedule and required drawings/test records. A family name alone is not enough for a controlled quotation.

Does factory attenuation data define the installed-link loss budget?

No. Installed-link loss also depends on route length, splices, connectors, bends and workmanship. Define the completed-link test method and pass limit separately.
