GYTA53 24-144F Double-Sheath Armored Outdoor Fiber Optic Cable

GYTA53

Product value summary

Use this page to prepare and validate an inquiry for a BWNFiber GYTA53 cable in the 24–144-fiber range. Confirm one count-specific construction, optical-fiber option, cable diameter, mechanical limit set, route declaration and drum plan before quotation or approval. A family name alone is not enough to release a purchase order.

Current evidence status: the model and working 24–144F scope come from a supplied BWNFiber draft. The controlled datasheet, construction drawing and test records were not supplied with this review. Technical values remain TBC — source required until approved by BWNFiber engineering.

Primary CTA: Send the route drawing, required fiber count, fiber specification, total length, drum-length plan, delivery destination and required submittal documents for a model-level review.

Short answer: what should a buyer confirm for GYTA53?

Confirm the exact part number and drawing revision first. Then match the selected fiber count to the approved tube plan, cable diameter, weight, tensile and crush limits, bend radius, temperature range, declared installation method and document set. Do not combine values from different count rows or assume that a generic armored-cable description approves this model for a specific route.

Working configuration — confirmation required

How should the GYTA53 construction be documented?

Publish one ordered cross-section for each approved variant. The construction drawing should identify the fiber, loose tube, filling or dry water-blocking materials, central strength member, core wrap, moisture barrier, inner sheath, armor and outer sheath in sequence. If steel and aluminum laminates are both used, name their exact positions rather than describing both as interchangeable “armor.”

Required drawing record: TBC — source required

Count-specific technical specifications

do not use for order release one mixed table unless each row is tied to an approved part number or count group.

Optical-fiber options and characteristics

Specify one optical-fiber grade per quoted configuration. The working draft listed G.652.D and several multimode descriptions, but it did not include a controlled option code or verified matrix. BWNFiber should publish only the grades available for this model and tie attenuation or other optical values to the approved fiber specification and measurement conditions.

Is this exact model approved for direct burial, duct or aerial use?

TBC — source required. The selected part number must state its permitted installation method and conditions. “Outdoor,” “armored” and “double sheath” describe attributes; they do not independently approve a cable for direct burial, duct pulling, aerial self-support or indoor routing.

For direct-burial projects, the current ITU-T L.101 recommendation addresses single-mode optical-fiber cables used in directly buried telecommunications applications and points to mechanical, environmental and test requirements. IEC 60794-3:2022 covers outdoor optical-cable requirements, including duct and directly buried applications. A standards reference is context, not proof that this BWNFiber model complies.

How to select the correct configuration

1. Identify every route segment. Separate direct burial, duct, conduit, aerial and building-entry sections.
2. Approve one model identity. Record the GYTA53 part number, datasheet revision and construction-drawing revision.
3. Select the fiber plan. State the fiber grade, count, working fibers, reserve, splice and termination capacity.
4. Match mechanical limits to installation. Compare approved tensile, crush, bend, impact and temperature limits with the pull plan and long-term route conditions.
5. Check interfaces. Match the cable OD and tolerance to duct fill, seals, glands, closures, clamps, entries and handling equipment.
6. Resolve metallic components. Obtain the project-approved grounding, bonding, isolation, lightning and termination approach.
7. Approve the drum plan. State total length, length per drum, route sequence, reel access, splice locations and length tolerance.
8. Close the evidence package. Approve the drawing, datasheet, deviation list, required test records, packing/marking and acceptance plan before PO release.

Testing and quality-control documentation

do not use for order release “factory tested,” a test method, a limit or a result unless the exact scope and record are available for this model. For the RFQ or submittal, state which records the buyer requires, such as:

• model-specific construction and dimensional inspection;
• optical-fiber/cable attenuation record at the agreed wavelengths;
• project-required mechanical or environmental test evidence;
• drum/length, marking and packing inspection;
• cable-end sealing and receiving inspection records;
• installed-link acceptance plan.

Installed-link insertion-loss testing and OTDR serve different purposes. FOA guidance treats insertion-loss testing against the loss budget as the primary acceptance measurement; OTDR is useful for event location, splice analysis and troubleshooting. The project owner must define the actual test wavelengths, directions, limits, trace format and sign-off responsibility.

RFQ CTA

Request a GYTA53 model and submittal review

Send BWNFiber:

• fiber grade and count;
• route drawing and installation method by segment;
• total length and required length per drum;
• duct, closure, gland and entry constraints;
• mechanical, temperature and environmental requirements;
• required standards, tests and document language;
• marking, packing, quantity and destination.

BWNFiber should return a model match, deviations, missing-evidence list and controlled quotation assumptions. Availability, sample length, MOQ, price, lead time and warranty remain subject to written confirmation.

What information is required for a GYTA53 quotation?

Provide the exact model or candidate model, fiber grade, fiber count, route and installation method, total length, length per drum, delivery destination, marking/packing requirements and the technical documents or tests required by the purchase specification.

Can values from different fiber-count rows be combined?

No. Use the diameter, weight, tube plan and mechanical limits that belong to the selected count and approved part number. If a row or condition is unclear, keep it open rather than substituting a value from another configuration.

Does an armored cable name prove direct-burial eligibility?

No. Armor describes a construction feature. Direct-burial eligibility must be declared for the exact model and reviewed against the route, local civil design and project specification.

What should the construction drawing show?

It should show the ordered layer sequence and identify the loose tubes, water-blocking materials, strength member, moisture barrier, inner sheath, armor and outer sheath for the quoted variant.

Why must cable diameter be confirmed by fiber count?

Cable diameter affects duct fill, pulling hardware, closure and gland compatibility, sealing and handling. Use the approved diameter and tolerance for the selected configuration.

How should metallic cable components be handled?

The project engineer should approve the grounding, bonding, isolation, lightning and termination method for the route and local requirements. The product page should identify metallic components but should not prescribe a universal field method.

Which standards may be relevant to a buried outdoor cable review?

ITU-T L.101 provides directly buried single-mode cable context, and IEC 60794-3 covers outdoor optical cables. The applicable edition, detailed requirements and model compliance must be stated in the purchase specification and supported by product evidence.

Is an OTDR trace enough for acceptance?

Not by itself. The acceptance plan should define insertion-loss testing against the approved loss budget and specify when OTDR traces are also required for event location, splice assessment or troubleshooting.

Can PE and LSZH be treated as interchangeable jackets?

No. Material names and fire/smoke ratings answer different route questions. Publish only the exact sheath compound and any tested rating documented for the quoted model.

What must be approved before releasing the purchase order?

Approve the part number, datasheet/drawing revision, count-specific specifications, route eligibility, interfaces, drum plan, deviations, required test records, packing/marking and commercial assumptions.
