GJPFJH 12F / 24F G.652.D LSZH Tight-Buffered Distribution Fiber Optic Cable

GJPFJH

Product Value Summary

The BWNFiber GJPFJH page covers two source-listed indoor distribution cable configurations: 12 fibers or 24 fibers, G.652.D single-mode fiber, 0.9 mm tight buffers, aramid-yarn strength members, and an LSZH outer sheath. Use the tables below to keep the selected fiber count tied to its cable diameter and weight, then send the route, length plan, quantity, marking and document requirements for quotation review.

Quick Answer for Buyers

Choose the 12F row when twelve fibers meet the working, reserve and termination-capacity plan; choose the 24F row when the approved design requires twenty-four fibers. Do not combine the 12F diameter or weight with the 24F count. The model code, fiber grade and LSZH material description do not by themselves prove a US plenum/riser listing, flame rating, outdoor suitability or project approval.

Configuration Snapshot

Configuration-control note: The figures above are retained from the supplied BWNFiber V4 record. The cited source files and exact source-row report were not included with this task, so Product/Quality Engineering must verify every row against the controlled datasheet before publication or quotation.

Key Features

• Two source-listed fiber counts: 12F and 24F.
• G.652.D single-mode fiber.
• 0.9 mm tight-buffered fibers.
• Aramid-yarn strength members.
• LSZH outer sheath.
• Count-specific diameter and weight values kept in separate rows.
• Installation and installed bend limits stated separately.

Cable Construction

Construction Boundary

This is a tight-buffered distribution construction, not a loose-tube cable and not a breakout cable with separately jacketed subunits. The 0.9 mm fibers can simplify indoor termination planning, but the connector, preparation method, panel hardware and approved termination procedure must still be specified. Do not infer water blocking, a ripcord, armor, UV resistance, rodent resistance, outdoor use, plenum listing or riser listing from the family name.

Temperature and Macrobending Fields

How to Select the Correct Configuration

1. Define the indoor route. State backbone, riser, horizontal pathway, telecom room, tray, conduit or cabinet sections and identify any indoor/outdoor transition.
2. Calculate the fiber count. Include working fibers, duplex pairs, redundancy, reserve and the capacity of panels or splice trays.
3. Select one controlled row. Choose either 12F / 6 mm / 37 kg/km or 24F / 8.3 mm / 61 kg/km. Do not mix fields between rows.
4. Check handling limits. Apply the selected diameter to the 20D installation and 10D installed bend rules after engineering confirms them.
5. Confirm the project rating. “LSZH” is a material description, not proof of a US plenum/riser listing or a named IEC/UL flame, smoke or halogen result.
6. Approve the termination plan. State direct termination, splicing or pre-termination, including panel capacity, connector/pigtail type, labels and test acceptance.
7. Approve the evidence pack. Request the current datasheet, drawing, material declaration and configuration-specific test or rating evidence required by the project.

Application Conditions

Candidate Uses

• Indoor building backbone routes.
• Riser, tray or conduit routes when the exact project rating and pathway requirements are approved.
• Telecom and equipment-room distribution.
• Indoor links that require 12F or 24F G.652.D single-mode cable and a compact tight-buffered structure.

Not Established by the Current Record

• Outdoor, aerial, direct-burial or wet-location use.
• Plenum, riser, CPR or any named fire classification.
• UV, water-blocking, rodent-resistant or armored performance.
• Connector compatibility or a finished connectorized assembly.
• Compliance with a named IEC, UL, NFPA, TIA, Telcordia or ISO/IEC cable standard.

These fields are TBC — source required and must not be inferred from competitor pages or the watermarked reference image.

Difference from Related Cable Types

The upper-level selection intent belongs to the indoor fiber cable selection page. This page should remain focused on the exact GJPFJH 12F/24F configuration.

Testing and Quality-Control Requirements

The supplied record lists optical, dimensional and mechanical values but does not include the underlying test reports, methods or release status. Before quotation approval or publication, request and verify:

• Current controlled datasheet and construction drawing with revision number.
• Fiber-grade declaration for G.652.D.
• Count-specific diameter and mass tolerances.
• Tensile, crush and bend test method, specimen and pass criteria.
• Installation, operation and storage temperature test basis.
• Attenuation measurement method and per-reel or batch record, if offered.
• Exact LSZH/fire/smoke/halogen test evidence required by the project.
• Cable marking, length tolerance, reel/drum record and final inspection release.

Do not claim “100% tested,” a named certification, a per-reel test report or compliance with a specific standard until BWNFiber supplies the evidence.

Packaging and Procurement Information

The following commercial fields were not supplied and remain TBC — source required:

• Standard reel or drum length.
• Maximum manufacturing length.
• Length tolerance.
• Reel/drum dimensions and gross weight.
• Minimum order quantity.
• Price, currency and Incoterms.
• Sample policy.
• Lead time.
• Warranty.
• Cable printing and packaging options.

Datasheet, Drawing and Test-Report Area

Is this a 12-fiber cable or a 24-fiber cable?

This page covers two source-listed configurations. Select one: 12F with a listed 6 mm diameter and 37 kg/km weight, or 24F with a listed 8.3 mm diameter and 61 kg/km weight. Product/Quality Engineering must verify the controlled rows before release.

Is GJPFJH a tight-buffered or loose-tube cable?

The supplied record identifies 0.9 mm tight-buffered fibers with aramid yarn and one outer sheath. It should not be described as a loose-tube cable.

Does the cable use G.652.D single-mode fiber?

Yes, G.652.D is the source-listed fiber category. ITU-T G.652 describes single-mode optical fiber and cable characteristics, but BWNFiber must still provide the model-specific fiber declaration and release evidence.

Does an LSZH sheath mean the cable is plenum- or riser-rated in the United States?

No. LSZH identifies material behavior; it does not by itself establish an NEC/UL plenum or riser listing. Confirm the exact building requirement and request evidence for the selected model.

Can this cable be installed outdoors?

Outdoor suitability is not established by the supplied record. Moisture, UV, water blocking, temperature and route approval require configuration-specific evidence. Treat this draft as indoor-only until BWNFiber confirms otherwise.

What bend limits are listed?

The internal draft lists 20 times the cable diameter during installation and 10 times the cable diameter after installation. Keep these conditions separate and verify them against the controlled datasheet.

What tensile and crush values are listed?

The draft lists 600/200 N short-/long-term tensile and 1000/200 N/100 mm short-/long-term crush for both counts. The test method and notation must be confirmed before publication or specification approval.

Are the attenuation values a complete link-loss budget?

No. The listed maximum values—0.36 dB/km at 1310 nm and 0.21 dB/km at 1550 nm—are fiber/cable fields. A link budget also accounts for installed length, splices, connectors and design margin.

What is needed to choose between 12F and 24F?

Count working fibers, duplex pairs, redundancy and reserve, then confirm that the pathway, panel and splice capacity can accept the selected diameter and fiber count. Do not choose by price alone.

What documents should a buyer request before approval?

Request the current datasheet, construction drawing, G.652.D declaration, dimension and mechanical limits, temperature range, required fire/smoke/halogen evidence, cable marking and the applicable optical or mechanical test records.

What information should be included in the quotation request?

State 12F or 24F, the indoor route, project rating, total length, length per reel or drum, quantity, destination, marking, termination plan and required approval documents.
