Quick Product Summary
This proposed BWNFiber product page covers a loose-tube, single-mode duct cable in 24-fiber and 48-fiber configurations. The working family designation is GYFY. Before ordering, the buyer and BWNFiber should confirm the selected fiber count, approved construction drawing, finished-cable dimensions, mechanical limits, installation method, reel schedule and required acceptance documents.
Current approval status: The 24F/48F variant mapping and numeric specification table require BWNFiber engineering approval. Do not use this draft as a released datasheet.
Primary action: Send the route and configuration inputs listed below to request a reviewed datasheet and quotation.
F and 48F Configuration Matrix
| Selection field | 24F option | 48F option | Approval status |
|---|---|---|---|
| Fiber count | 24 fibers | 48 fibers | 24F/48F family scope requires final approval |
| Fiber category | G.652.D single-mode, TBC | G.652.D single-mode, TBC | Approved source required |
| Cable family | GYFY, TBC | GYFY, TBC | Sellable model/SKU required |
| Loose-tube map | TBC — source required | TBC — source required | Engineering drawing required |
| Central strength member | FRP, TBC | FRP, TBC | Confirm for each variant |
| Water-blocking system | TBC — source required | TBC — source required | Define tube filling and core blocking separately |
| Outer sheath | Black PE, TBC | Black PE, TBC | Confirm grade and applicable environmental properties |
| Overall diameter | TBC — source required | TBC — source required | Do not reuse one shared value without approval |
| Approximate cable weight | TBC — source required | TBC — source required | Confirm tolerance for each variant |
| Standard reel length | TBC — source required | TBC — source required | Confirm allowed tolerance and drum size |
Do not combine one variant’s tube map, diameter or packing data with the other variant. The approved quotation and datasheet should identify one complete configuration.
Cable Construction
The supplied BWNFiber draft and schematic indicate a stranded loose-tube design with a central strength member, water-blocking elements, a ripcord and an outer sheath. The source draft identifies PBT loose tubes, an FRP central strength member and a PE outer sheath; these material statements must be checked against the approved 24F and 48F drawing before release.
Draft caption: Watermarked construction schematic supplied with the source package. Use it as a visual reference only; it is not an approved dimensional drawing or test record.
Technical Specifications
| Parameter | Approved value |
|---|---|
| Fiber count | 24F / 48F — variant scope pending final approval |
| Fiber type | G.652.D single-mode — TBC, source required |
| Cable designation / SKU | TBC — BWNFiber must assign or approve |
| Tube count and fibers per tube | TBC — approved 24F/48F map required |
| Cable diameter and tolerance | TBC — source required for each variant |
| Cable weight and tolerance | TBC — source required for each variant |
| Attenuation by wavelength | TBC — approved optical table and test method required |
| Chromatic-dispersion values | TBC — approved fiber specification required |
| Short- and long-term tensile load | TBC — source required |
| Short- and long-term crush resistance | TBC — source required |
| Minimum bend radius, loaded/unloaded | TBC — source required |
| Installation / operating / storage temperature | TBC — source required |
| Applicable standards and test methods | TBC — do not claim compliance without scope evidence |
The cable-fiber attenuation values, once approved, do not represent a complete installed-link budget. Connectors, splices, route length, repair allowance and test method must be handled separately in the project design and acceptance plan.
Duct Route Compatibility and Selection Conditions
Use this product page only for an approved duct-route configuration. Before selection, provide:
- Whether the route will use pulling, blowing/jetting or another approved method.
- Duct and innerduct dimensions, route length, bends, chambers and entry constraints.
- Required fiber count and fiber specification.
- Maximum reel length and site handling limits.
- Required finished-cable tensile, crush, bend and temperature limits.
- Local jacket, fire, environmental and documentation requirements.
The product name alone does not establish direct-burial, self-supporting aerial, indoor fire-rating, rodent-resistance, UV-resistance or air-blowing suitability. Add those claims only when the exact configuration has supporting evidence.
How to Select the Correct Configuration
- Confirm the route. Separate duct sections from aerial, direct-burial and indoor transitions.
- Choose the fiber count. Select 24F or 48F based on the approved network design and spare-fiber policy.
- Approve the fiber and construction. Confirm the G.652.D requirement, tube map, strength system, water-blocking design and sheath.
- Check the finished cable against the route. Use the approved diameter, pulling load, bend radius and temperature limits—not generic fiber rules.
- Approve the reel schedule and marking. Confirm total length, length per reel, tolerance, drum dimensions and cable legend.
- Define acceptance evidence. State which datasheet, drawing, test report or inspection record must accompany the quotation, sample or production lot.
Differences from Related Cable Families
| Related page/family | Main difference | Ownership rule |
|---|---|---|
| BWNFiber fiber-optic-cable category | Broad route and family selection | Category owns generic selection; this page owns one approved 24F/48F configuration |
| Standard Loose Tube No-armored Cable | Current live page describes several loose-tube families with a metallic central strength member | Do not imply interchangeability with the proposed FRP-based GYFY build |
| BWNFiber GYFTZ page | Existing dielectric loose-tube product/family | Engineering must define GYFY versus GYFTZ before either page makes comparison claims |
| P169 all-dry duct cable draft | Wider count range and all-dry positioning | P175 must prove a different water-blocking/construction role or be merged |
| Armored / Direct Burial Cable | Mechanical/environmental route family | Do not position this duct cable as direct-burial cable without an approved build |
| ADSS outdoor cable | Self-supporting aerial route family | Do not use aerial-span language on this page |
Testing, Documents and Approval Boundaries
Ask BWNFiber to identify which documents are available for the exact quoted variant:
- Approved product datasheet
- Construction drawing with tube/fiber map
- Cable-marking sample
- Reel/drum schedule
- Applicable type-test or routine-test list
- Lot-specific inspection or test record, if offered
- Packaging and shipping-mark details
No test method, result, standard compliance or certification is promised in this draft. A sample or first-article approval does not automatically approve every later production lot; define the production acceptance evidence in the purchase order or quality agreement.

Request a Reviewed Configuration and Quotation
Send BWNFiber your selected fiber count, duct route, placement method, total length, reel schedule, required limits, marking and document list. Ask for a configuration-matched datasheet and quotation before approving the product for a project.
Primary CTA: Request the approved 24F/48F configuration and quotation
Secondary CTA: Ask which drawing and test/inspection records are available for the quoted variant
