GJFJV 1F G.657.B3 3.0mm TPU Distribution Fiber Optic Cable
GJFJV 1F G.657.B3 3.0mm TPU Distribution Fiber Optic Cable for indoor building or equipment-room routes at 1F. Confirm jacket and fiber grade before quoting.

Configuration summary
This supplied BWNFiber record describes a one-fiber cable with G.657.B3 optical fiber, a 0.9 mm PVC tight buffer, aramid-yarn strength members, a TPU outer sheath and a nominal 3.0 mm finished diameter. It is scoped to indoor fiber distribution. Other fiber counts, fiber grades, buffer materials, jacket materials or diameters are separate configurations and must not be inferred from this page.
The product is supplied as bulk cable. No connector, connector polish, pre-termination, equipment compatibility, flame rating, certification, MOQ, price, stock status, lead time or warranty is established by the supplied V4 record.

Supplied cable construction
| Component | Supplied V4 record |
|---|---|
| Optical fiber | 1 × G.657.B3 |
| Tight-buffer size and material | 0.9 mm PVC |
| Strength member | Aramid yarn |
| Outer sheath | TPU |
| Finished cable diameter | 3.0 mm nominal |

The supplied cross-section illustration identifies the outer sheath, aramid yarn, optical fiber and tight buffer. It is a labeled construction illustration, not a product photograph or test record. Confirm that the approved drawing matches the illustrated layer order and materials before publication.
Supplied optical characteristics
| Parameter | Wavelength | Supplied V4 value |
|---|---|---|
| Attenuation | 1310 nm | ≤0.35 dB/km |
| Attenuation | 1550 nm | ≤0.21 dB/km |
| Cable cut-off wavelength | — | ≤1260 nm |
These figures are model-specific claims from the supplied V4 record and require engineering sign-off. They are not a complete installed-link budget and do not include connector, splice, bending, launch or measurement allowances.
Supplied mechanical limits
| Parameter | Condition | Supplied V4 value |
|---|---|---|
| Minimum bend radius | Static | 10D |
| Minimum bend radius | Dynamic | 20D |
| Tensile strength | Long term | 90 N |
| Tensile strength | Short term | 150 N |
| Crush strength | Long term | 100 N/cm |
| Crush strength | Short term | 300 N/cm |
D is the approved finished cable diameter. For a nominal 3.0 mm cable, do not convert 10D or 20D to an installation value until the diameter tolerance and engineering notation are confirmed. G.657.B3 identifies the optical-fiber category; it does not replace the finished cable’s handling limits.
Application and compatibility boundaries
- Use the record only for an indoor distribution route that the approved datasheet covers.
- G.657.B3 is a bend-insensitive single-mode fiber category intended for short-reach access and indoor or near-building applications. It is not automatically equivalent to G.652.D in every fiber attribute.
- Confirm the link design, splicing plan, termination method and active-equipment requirements for the project. This bulk-cable record does not establish connector or transceiver compatibility.
- A TPU material name does not establish a UL plenum, riser, flame, smoke, halogen, UV, water, oil, abrasion or chemical-resistance rating. Every required rating needs model-specific evidence.
- Do not extend the indoor application to outdoor, direct-burial, aerial or wet routes without an approved model document covering those conditions.
- Working, storage, transport and installation temperature ranges are TBC — source required.
How to specify the correct configuration
- Confirm whether the approved model is
GJFJV,GJFJUor another BWNFiber designation. - Confirm 1F G.657.B3 and the required optical values against the current datasheet.
- Confirm the 0.9 mm PVC tight buffer, aramid yarn and TPU outer sheath against the construction drawing.
- Confirm the finished diameter and tolerance, mass, bend, tensile and crush values.
- State the indoor pathway, termination method and any code or material-performance requirement.
- Request the exact approval documents needed for the project before placing a production order.
Difference from related BWNFiber cable records
| Related record | Key difference | Page-role boundary |
|---|---|---|
| GJFJV indoor fiber optic cable family page | Broad GJFJV family and indoor selection intent | The existing family URL should remain the broad owner; this proposed page must own only the approved 1F/G.657.B3/3.0 mm/TPU SKU |
| 1F G.657.B3 3.0 mm round drop cable | Supplied as an LSZH drop-cable record with different mechanics | Do not merge the TPU distribution specification with the LSZH drop-cable specification |
| GJFJV 1F LSZH simplex cable | LSZH jacket and alternative fiber/diameter configuration | Jacket, fiber options and mechanical rows are not interchangeable |
| GJFJV 2–48F LSZH distribution cable | Multi-fiber LSZH distribution family | This page must remain fixed at 1F and TPU |
If BWNFiber cannot verify the model designation and a distinct sales/production SKU, consolidate this material into the existing GJFJV family owner rather than publishing another product URL.
Testing and quality-control documents
No product-specific test method, equipment list, sampling plan, test report or certificate was supplied for this review. Before approval, request the documents that the project actually requires, which may include:
- current signed datasheet and construction drawing;
- fiber declaration for G.657.B3;
- dimensional and mass inspection record;
- attenuation test record with wavelength, method and acceptance limit;
- mechanical test record for the quoted tensile, crush and bend values;
- TPU material declaration and any project-required rating evidence;
- batch identification and final inspection record.
Availability and report format are TBC — source required. Do not promise a document until BWNFiber confirms it.

Frequently asked questions
Which fiber count does this page cover?
It covers one fiber only. A different fiber count is a separate configuration and must be checked against its own datasheet.
Is the correct model GJFJV or GJFJU?
The supplied V4 record says GJFJV, but the stated TPU sheath conflicts with BWNFiber’s current public explanation of the V designation. The official model is therefore TBC and must be confirmed from the approved datasheet and drawing before publication or quotation.
Which fiber grade is specified?
The supplied record lists G.657.B3. ITU-T describes category B fiber as bend-insensitive single-mode fiber intended for short-reach access and indoor or near-building applications. Confirm the complete link and splice requirements; the fiber category alone does not approve the finished cable for a route.
What is the supplied cable diameter?
The V4 record lists 3.0 mm nominal. Diameter tolerance is not supplied and must be confirmed before using the dimension for conduit fill, hardware fit or bend-radius calculations.
What materials are listed in the construction?
The supplied record lists a 0.9 mm PVC tight buffer, aramid-yarn strength members and a TPU outer sheath. Engineering must confirm the layer construction and materials.
Does TPU mean the cable has a US plenum or riser rating?
No. A material name is not a fire or building-code classification. Request the exact model’s applicable listing and test evidence for the installation jurisdiction.
What bend limit should an installer use?
The supplied record lists 10D static and 20D dynamic. Use only the engineering-approved finished-cable limit; do not substitute the optical fiber’s minimum design radius.
Are connectors included?
No connector or pre-termination option is specified in the supplied record. If a finished assembly is required, define both connector ends, polish, length, labeling and test requirements as a separate configuration.
Can this cable be installed outdoors?
Outdoor use is not established. UV, moisture, temperature, support and transition requirements need a model specifically documented for the route.
What should be included in a quotation request?
Include the confirmed model, route, termination method, total length, reel plan, quantity, marking, color, destination and required approval documents or ratings.
