GJYXFCH 2F G.657.A2 FRP LSZH Figure-8 FTTH Drop Fiber Optic Cable

Product Value Summary

This page covers one order configuration: a GJYXFCH Figure-8 FTTH drop cable with two G.657.A2 single-mode fibers. The current internal record describes an LSZH sheath, two GFRP reinforcement elements and a separate steel messenger. These component details require final confirmation against the controlled cross-section drawing before release.

Buyer summary: Use this page to identify the exact 2F construction and prepare an RFQ. Do not transfer dimensions, load limits, bend limits, packing or test results from another GJYXFCH model. For an aerial route, send the span, support hardware, wind/site conditions and building-entry details for engineering review.

Interfaces and End Options

No connector or polish option is established by the supplied V4 text. Quote the cable as unterminated only if BWNFiber confirms that end condition. If pre-terminated ends are required, state the connector family, polish, end A/end B, pulling protection and test limits as a separate approved configuration.

Fiber and Configuration Boundary

G.657.A2 is a bend-loss-insensitive single-mode fiber category used in access and other networks where reduced macrobending loss is required. It does not by itself establish the finished cable’s installation bend radius, tensile load, crush resistance, span, jacket approval or environmental rating. The controlled cable datasheet must provide those finished-product limits.

Compatibility and Application Conditions

The proposed use is an FTTH subscriber drop requiring a compact Figure-8 construction. Before approval, confirm:

the complete route from distribution point to premises entry;
aerial span, sag, wind/site conditions, support hardware and attachment points;
indoor/outdoor transition and local pathway requirements;
fiber grade and compatibility with the installed optical network;
finished-cable mechanical, bend and temperature limits;
sheath rating evidence required by the project.

This draft does not establish direct-burial, duct, rodent-resistant, waterproof, all-dielectric or universal indoor approval.

Use BWNFiber’s fiber optic cable installation guidance for general handling context, but release the route only against this model’s approved datasheet and project conditions.

How to Select the Correct Configuration

Confirm the owner model: GJYXFCH, 2F, G.657.A2.
Confirm the route: aerial, wall, entry and indoor transition details.
Approve the component map: two GFRP reinforcement elements plus the separate messenger.
Approve model limits: dimensions, weight, tensile, crush, bend and temperature.
Define the ends: unterminated or the exact pre-terminated interface.
Define the order: total length, length per drum, quantity, marking and documents.

Differences from Related Products

Related BWNFiber page	Difference to confirm	When to review it
FTTH GJYXFCH 1F – FRP	1F configuration and potentially different support construction	When one fiber is sufficient or a non-identical messenger system is required
FTTH Indoor/Outdoor Round 2F G.657.A2 PE Cable	Round PE construction rather than this Figure-8 LSZH configuration	When route, sheath or cross-section requirements differ
FTTH Drop Cable category	Broad family selection across indoor, outdoor, aerial and protected routes	When the correct construction is not yet known

Do not copy values between these pages. Each model’s controlled datasheet governs.

Testing and Quality-Control Requirements

The supplied V4 contains partial torsion and temperature-cycle rows, but their source-table alignment has not been approved. Before publication or order release, request an engineer-approved test matrix containing:

finished-cable test name and current referenced method;
sample length, load/fixture, cycles and environmental conditions;
wavelength and acceptance criterion;
before/after result and report identifier;
model/configuration covered by the report.

TBC — source required: production test scope, test frequency, equipment, limits and report availability.

Packaging and Procurement

Packing is quotation-specific in this draft. V4 contains a 1 km/drum table and pallet values, but its own review note says the packing prose and count-specific table must be reconciled. do not use for order release a universal drum length or pallet quantity until BWNFiber approves one packing matrix for this exact configuration.

FAQ

Frequently Asked Questions

What does this GJYXFCH page cover?

It is the offline merge draft for BWNFiber’s existing 2-fiber GJYXFCH product URL. The proposed configuration uses G.657.A2 single-mode fiber in a Figure-8 drop-cable construction. Final component and performance values require engineering approval.

Are the GFRP elements and steel messenger the same component?

No. The current internal record describes two GFRP reinforcement elements around the optical unit and a separate steel messenger for support. BWNFiber must confirm this layout against the controlled cross-section drawing before release.

Does G.657.A2 define the finished cable bend radius?

No. G.657.A2 describes the optical fiber category and macrobending performance. The finished cable’s installation and service bend limits must come from the model-specific cable datasheet.

Can this cable be used for any aerial span?

No universal span is established in the supplied evidence. Send the span, sag, wind/site conditions, hardware and attachment details for review against the approved finished-cable load limits.

Does LSZH prove that the cable meets every indoor fire requirement?

No. LSZH identifies a material behavior category, not every project-specific fire, smoke or pathway classification. Request the exact test standard and classification required by the project.

Is this cable direct-burial or duct rated?

Not from the current evidence. This draft does not claim direct-burial, duct, waterproof, armored or rodent-resistant approval.

Is the cable supplied with connectors?

The supplied V4 text does not establish an end condition. State unterminated or the exact connector and polish requirement in the RFQ, and obtain a configuration-specific confirmation.

Which dimensions should be used for approval?

The internal record lists 2.0 ± 0.1 mm × 5.0 ± 0.2 mm, pending confirmation against the controlled drawing. Do not reuse dimensions from another GJYXFCH model.

What packing length is available?

Packing is TBC. State the required length per drum or roll in the RFQ; BWNFiber must confirm the exact packing matrix for this configuration.

What documents should a buyer request?

Request the controlled datasheet, cross-section drawing, model-specific test matrix/report, packing specification and any project-required compliance evidence. Check that each document identifies the same configuration and revision.

What information is required for a quotation?

Provide the exact model/configuration, route, span and hardware where applicable, total length, length per drum, quantity, end condition, marking, required documents and delivery destination.
