4–144F Double-Sheath Direct Buried Fiber Optic Cable

Product summary

BWNFiber’s supplied GYTA53 record covers 4F, 6F, 8F, 12F, 24F, 48F, 72F, 96F and 144F configurations in a double-sheath outdoor cable construction. The record lists PBT loose tubes, tube filling compound, PP fillers, a steel-wire central strength member, water-blocking jelly, an MDPE inner sheath and an HDPE outer sheath.

Use one count group and one optical option in an RFQ. Do not combine values from different rows. The exact model identifier, fiber grade, finished-cable mechanical limits, test conditions and direct-burial approval must be confirmed against the revision-controlled datasheet before a purchase order is released.

Short answer: choose the fiber count from the count-specific table, check the cable diameter and weight against the closure, seal and drum plan, then send the route, length, marking and evidence requirements for a controlled quotation.

Key features from the supplied record

Quick technical specification

Count-specific construction, diameter and weight

Engineering note: the supplied table uses grouped notation for 4/6/8/12F and lists —/- for some central-member PE-layer fields. Confirm the exact row before publishing or quoting.

Common sheath and tube values

Optical options and evidence status

The supplied record includes multimode-style 850/1300 nm values and a G.651 OM300 reference in the count table, but it does not clearly identify one selected fiber grade or define the “before cabling” and “after cabling” conditions. Treat the following as a source-review matrix, not a final cable guarantee.

Do not add attenuation, bandwidth, numerical-aperture, PMD, link-budget or test-result claims until the fiber engineer confirms the source row, unit, method, condition and selected option.

Temperature information

These ranges are transcribed from the supplied record. Confirm they apply to the exact finished-cable model and revision.

How to select the configuration

1. State the required fiber count and the selected fiber grade; do not send a mixed optical table.
2. Match the count row to the approximate diameter, weight, closure port, seal and handling plan.
3. Confirm the route as direct burial, duct, conduit or a transition; “armored” alone does not prove direct-burial approval.
4. Request the finished-cable tensile, crush, bend and test conditions for the selected model.
5. Confirm drum length, reel dimensions, quantity, marking, destination and required inspection records.
6. Approve the model, drawing revision, route interfaces and quotation as one controlled package.

For route selection, see the armored/direct-burial cable selection guide and the direct-burial fiber optic cable overview. These pages own broad route and educational intent; this page should own the exact product/count evidence.

Interfaces, compatibility and application boundary

This is a bulk outdoor cable record. No factory connector, connector polish, gender, polarity or terminated interface is specified in the supplied V4 file. TBC — source required: any termination, closure, gland, bonding, grounding or indoor-transition requirements.

The cable may be considered for a direct-buried or other outdoor route only after the exact model datasheet, route design, environmental limits and project acceptance requirements are matched. A PE/HDPE sheath, a steel member or the GYTA53 name does not by itself approve a building entry, aerial span, fire-rated indoor pathway or local civil installation.

Packing and procurement information

The supplied packing table lists 4,000 m rows for each count, with different reel dimensions for 96F and 144F. Use the count-specific values below for comparison and confirm the controlled packing revision before quotation.

Required information for an RFQ

Send:

• selected fiber count and fiber grade;
• exact model or requested GYTA53 configuration;
• direct-buried, ducted or mixed route, including transitions;
• total cable length, length per drum and quantity;
• cable marking text and delivery destination;
• closure, seal, pulling and metallic-component requirements;
• applicable project standard and required test/inspection documents.

Request the controlled datasheet, construction drawing, deviation list and document revision before releasing a purchase order.

Testing and quality-control process

The supplied V4 file does not provide a complete finished-cable test plan or report. The final page must not claim “100% factory tested,” certification, routine testing, witness testing or a pass result unless a model-specific report and method are available. Add the following only after QA confirmation:

RFQ CTA

Request a controlled GYTA53 datasheet and quotation. Include the selected count, fiber grade, route, total length, drum plan, marking, destination and required evidence. Use BWNFiber Contact Us after the live form and CTA target are verified.

Which fiber counts are listed for this GYTA53 record?

The supplied record lists 4F, 6F, 8F, 12F, 24F, 48F, 72F, 96F and 144F. Select one count row and confirm its construction and optical option before ordering.

Is this cable automatically approved for direct burial?

No. The record is named for direct-buried use, but approval still depends on the exact model, route, soil/loading conditions, mechanical limits, metallic-component treatment and project documents.

What are the sheath materials?

The supplied table lists an MDPE inner sheath and an HDPE outer sheath, both black, with 0.8 mm inner-sheath and 1.8 mm outer-sheath thicknesses. Confirm the values against the controlled drawing.

Does the page specify connectors or a terminated interface?

No. It describes bulk cable. Connector type, polish, gender, polarity and termination hardware are not specified and must not be inferred.

How should I choose between 96F and 144F?

Compare the count-specific diameter, weight, tube allocation and drum dimensions with the closure, pathway, handling and reserve-fiber requirements. Ask for the controlled drawing and finished-cable mechanical table before approval.

What should be included in a quotation request?

State the count and fiber grade, route, total length, drum plan, quantity, marking, destination, closure/transition requirements and required inspection or test documents.

Can I combine the optical values in the table?

No. The source record does not define the fiber-grade and before/after-cabling conditions clearly enough to combine them. Engineering must identify the selected option and test basis.

What is the listed temperature range?

The supplied record lists −40°C to +60°C for operation and storage/transport, and −20°C to +60°C for installation. Confirm these ranges for the selected revision.
