GYFTY-nB1.3 48F G.652.D Anti-Rodent Loose Tube Fiber Optic Cable
GYFTY-nB1.3 48F G.652.D Anti-Rodent Loose Tube Fiber Optic Cable for outdoor plant use at 48F. Confirm model, fiber count and installation method against the source drawing.
Product Summary
GYFTY-nB1.3 is presented in the supplied BWNFiber record as a 48-fiber outdoor loose-tube cable using G.652.D single-mode fiber, an FRP central strength member, glass yarn around the cable core and an HDPE outer sheath. The listed arrangement is 12 fibers per tube, four loose tubes and two fillers, with a nominal 9.8 mm cable diameter.
This is a configuration-validation page, not a general outdoor-cable guide. Before approval, match the quotation, current datasheet and drawing to the exact model suffix, 48F count, G.652.D grade, tube plan, glass-yarn construction and required installation route.
Buyer short answer: Use this record to prepare an RFQ for the stated 48F configuration. Do not treat the words anti-rodent, outdoor, aerial or duct as route approval. Ask BWNFiber to confirm the controlled construction, test conditions, pulling method, support hardware and acceptance documents for the project.

What the Glass-Yarn Construction Does—and Does Not Prove
The supplied cross-section identifies glass yarn outside the stranded cable core. This supports the proposed glass-yarn anti-rodent positioning at the drawing-review level. It does not prove a universal degree of rodent protection, a particular test method, direct-burial suitability, self-supporting aerial performance, UV rating, fire rating or all-dielectric status for every production variant. Those claims require an exact BOM, drawing and applicable test or declaration.
Provisional Mechanical and Environmental Values
The values in this section are transcribed from the supplied V4 record. They are not released specifications because the original controlled source and test basis were not available in the reviewed folder.
| Parameter | Supplied V4 value | Information still required |
|---|---|---|
| Tensile strength | 3,000 N | Short-term/long-term label, method, loaded length, duration, optical limit and report identity |
| Crush resistance | 1,000 N/100 mm | Method, platen geometry, duration, optical/physical acceptance and report identity |
| Minimum bend radius during installation | 20 × cable diameter | Loaded condition, temperature and source revision |
| Minimum bend radius after installation | 10 × cable diameter | Unloaded condition, temperature and source revision |
| Operating temperature | -30 °C to +60 °C | Test/profile basis and exact label |
| Installation temperature | -30 °C to +60 °C | Handling/pulling conditions and exact label |
| Storage temperature | -40 °C to +70 °C | Conditioning/profile basis and exact label |
Mechanical headline values are comparable only when the model, method, specimen, setup, load, duration, optical response and physical acceptance criteria match. For the evidence fields behind tensile, crush and bend values, review BWNFiber’s armored fiber cable mechanical-ratings guide. The guide is a document-review framework; it is not proof that this model passed a test.
Provisional G.652.D Optical Characteristics
The V4 record lists the following optical values. Confirm that the controlled G.652.D fiber certificate and cable datasheet use the same definitions, conditions, units and revision before publication.
| Parameter / condition | Supplied V4 value | Release status |
|---|---|---|
| Mode-field diameter at 1310 nm | 9.2 ± 0.4 µm | TBC — source required |
| Cladding diameter | 125 ± 1 µm | TBC — source required |
| Core/cladding concentricity error | ≤0.6 µm | TBC — source required |
| Cladding non-circularity | ≤1.0% | TBC — source required |
| Cable cut-off wavelength (λcc) | ≤1260 nm | TBC — source required |
| Fiber cut-off wavelength (λc) | 1180–1330 nm | TBC — source required |
| Primary coating diameter, excluding color layer | 245 ± 10 µm | TBC — source required |
| Primary coating diameter, including color layer | 250 ± 15 µm | TBC — source required |
| Coating/cladding concentricity error | ≤12.5 µm | TBC — source required |
| Fiber curl radius | ≥4 m | TBC — source required |
| Attenuation at 1310 nm | ≤0.36 dB/km | TBC — source required |
| Attenuation at 1550 nm | ≤0.21 dB/km | TBC — source required |
| Chromatic dispersion, 1288–1339 nm | ≤3.5 ps/(nm·km) | TBC — source required |
| Chromatic dispersion at 1550 nm | ≤17 ps/(nm·km) | TBC — source required |
| Zero-dispersion wavelength | 1300–1324 nm | TBC — source required |
| Zero-dispersion slope | ≤0.092 ps/(nm²·km) | TBC — source required |
| Macrobending loss, Φ 60 mm, 100 turns at 1550 nm | ≤0.1 dB | TBC — test/source required |
The V4 line Dispersion mode bias: 0.5 ps/km1/2 is withheld from the publishable table because the metric name and unit are unclear. BWNFiber Engineering must identify the intended parameter and restore the controlled wording if applicable.
ITU-T G.652 defines characteristics of single-mode optical fiber and cable; the fiber designation does not approve the finished cable’s route, mechanical limits or installed-link loss budget. Connector and splice losses must be handled separately in link design and acceptance.
Application and Compatibility Boundaries
Duct Installation
For a duct route, confirm duct size and occupancy, pulling length and method, maximum pulling tension, sidewall pressure where applicable, bend path, water-management plan, lubricant compatibility, handhole access and termination or splice locations. The 3,000 N value cannot be used as an installation limit until its condition and test basis are confirmed.
Supported Aerial Installation
The supplied record lists aerial installation, but it does not establish that this cable is ADSS or self-supporting. Confirm messenger/support method, span, sag, wind and ice conditions, pole hardware, clearances, installation tension and the exact approved cable load data before aerial use.
Rodent-Exposure Review
Glass yarn is shown as the anti-rodent element. Project approval still needs the material definition, coverage/construction, required rodent-resistance method or customer criterion, and any route-specific protective measures. Compare this construction with metallic armor only after electrical/grounding constraints, mechanical exposure, route method and test evidence are defined. See BWNFiber’s outdoor cable rodent and water-damage guide for the selection questions; that guide does not certify this model.
Interfaces and Termination
No connectorized interface is identified in the supplied product record. Treat this as bulk cable unless the quotation defines factory termination. Confirm closure, splice tray, gland, duct, support hardware and termination capacity against the 48F count and final cable diameter.
How to Select and Approve This Configuration
- Lock the route. Mark each duct, supported aerial, building-entry and termination segment. Do not approve a single construction for every segment by default.
- Freeze the optical requirement. Confirm G.652.D, wavelengths, distance, equipment interfaces, capacity, reserve fibers and the project loss budget.
- Match one controlled model. Require the quotation, datasheet and drawing to identify GYFTY-nB1.3, 48F, the same suffix and revision.
- Verify the construction. Check the 4-tube/2-filler plan, 12 fibers per tube, FRP central member, glass-yarn layer, HDPE sheath, outside diameter and tolerances.
- Verify route limits. Compare the documented pulling, crush, bend and temperature conditions with the installation design. A larger headline value is not automatically a better match.
- Define acceptance evidence. State required fiber certificate, dimensional inspection, drum test, test methods, report fields, marking, packaging and deviation-control process.
- Release the order only after document approval. Keep the approved datasheet, drawing, quotation, deviation log and purchase specification on the same revision.
How This Product Differs From Adjacent Cable Families
| Adjacent family | Main distinction to verify | Do not assume |
|---|---|---|
| Standard metallic loose-tube cable | Metallic central member and/or laminate may change electrical, grounding and mechanical considerations | That a broad standard loose-tube page describes this FRP/glass-yarn configuration |
| ADSS cable | Self-supporting design is selected against span, sag, wind, ice and hardware requirements | That the word aerial makes GYFTY-nB1.3 an ADSS cable |
| Steel-tape armored/direct-burial cable | Metallic armor can address a different mechanical/rodent requirement and may introduce bonding/grounding considerations | That glass yarn and steel tape provide identical protection or route approval |
| General GYFTY family page | Family pages support discovery and configuration comparison | That one family table proves this exact 48F model and revision |
Use the fiber optic cable selection page for route-level family selection. Use this product page only for the exact 48F configuration after its controlled evidence is approved.

FAQ
Frequently Asked Questions
What exact configuration does this page cover?
It covers the proposed GYFTY-nB1.3 configuration with 48 G.652.D fibers arranged as 12 fibers per tube in four loose tubes, plus two fillers. These fields remain provisional until they are tied to the current controlled datasheet and drawing.
How is rodent protection provided?
The supplied V4 record and cross-section identify glass yarn around the cable core. The material, coverage and applicable rodent-resistance criterion still need controlled product evidence. Do not interpret the anti-rodent label as a guarantee against all rodent damage.
Is this cable metallic-armored?
The supplied construction lists FRP, glass yarn and an HDPE sheath; it does not list steel or aluminum armor. Confirm the full BOM before calling the finished cable all-dielectric or non-metallic, and do not describe glass yarn and metallic tape armor as equivalent.
Can this cable be installed in a duct?
The V4 record lists duct installation. Project approval still requires the duct route, pulling plan, bend path, cable limits, accessories and test/document requirements to match the exact model.
Can this cable be used for aerial installation?
Only after the support method and route loads are approved. The word aerial does not show that the cable is self-supporting or that it meets a particular ADSS span requirement.
What bend limits are listed?
The V4 record lists 20 times the cable diameter during installation and 10 times the cable diameter after installation. The controlled source must confirm the loaded/unloaded conditions, temperature and exact model scope before release.
Are the attenuation values an installed-link loss budget?
No. The listed values are provisional cabled-fiber attenuation limits at 1310 nm and 1550 nm. A link budget must separately include cable length, splices, connectors, passive components, operating wavelength, engineering margin and acceptance method.
What should a buyer request before approving the cable?
Request a revision-controlled datasheet and drawing, fiber certificate, route-specific mechanical evidence, dimensional and drum-test records, marking/packaging details and a written response to every project requirement or deviation.
What information should be included in the quotation request?
State the exact model reference, 48F G.652.D configuration, route and installation method, length per drum, mechanical/environmental criteria, rodent requirement, interfaces, required documents, marking, packaging, quantity and destination.
