What the GYFXTC8Y model identifies
The GYFXTC8Y product page describes an outdoor figure-8 self-supporting fiber optic cable with a central loose tube cable core and an integrated metal messenger support element. The figure-8 profile combines the messenger and optical cable core for aerial pole-route installation.
That description is a starting point, not a complete engineering approval. The final cable selection still depends on the route, fiber requirements, environmental loads, installation method and buyer documentation.
RFQ fields to confirm before quotation
| RFQ field | What to state | Why it matters |
|---|---|---|
| Installation and route | Aerial pole route, attachment method, approximate span or pole spacing, temperature range and whether the route passes near power infrastructure. | Confirms whether a figure-8 metal-messenger design is appropriate for the route. |
| Fiber requirement | Fiber type, fiber count, attenuation limits and any approved fiber or test-document requirement. | The tube layout and optical acceptance requirements depend on the project specification. |
| Messenger and mechanics | Required messenger construction, span inputs, sag allowance, wind and ice assumptions, installation tension and hardware interface. | Do not infer span capability from the model code alone. |
| Cable construction | Central loose tube, water blocking, outer sheath, nominal diameter, minimum bend radius and any project-specific protection. | Creates a defined construction for quotation and later inspection. |
| Drum and delivery | Required drum length and tolerance, quantity, marking, cable-end sealing, packing, destination and delivery terms. | Prevents a technically acceptable cable from becoming a logistics mismatch. |
| Testing and documents | Optical, dimensional, mechanical or environmental test records, inspection plan, compliance statement and deviation schedule. | Defines how the buyer will verify the offered construction. |
GYFXTC8Y buyer checklist
- Write the installation method and route environment before naming the cable.
- State fiber type, fiber count, optical limits and required test evidence.
- Provide pole spacing or span inputs together with sag, wind, ice, temperature and installation-tension assumptions when available.
- Confirm the messenger, sheath, water-blocking, diameter and bend-radius requirements.
- Define drum length, quantity, markings, packaging, destination and document requirements.
- Ask the supplier to list every deviation instead of treating a simple “complies” response as complete.
When to compare ADSS or another Figure-8 cable
Use the ADSS versus Figure-8 aerial selection guide when the route may require no metallic messenger or has power-line exposure. Use the GYC8S versus GYTC8S selection guide when the buyer is comparing other figure-8 constructions and cable-core protection.
The comparison should stay tied to the project route and approved drawing. A generic label such as “aerial cable,” “armored” or “self-supporting” is not enough to establish the correct construction.

Frequently asked questions
What should a GYFXTC8Y RFQ include?
State the aerial route, pole spacing or span inputs, fiber type and count, messenger and sheath requirements, environmental conditions, drum length, quantity, marking, packaging, destination and required test documents.
Does the model name prove a fixed span?
No. Span capability depends on the approved cable design, route geometry, sag, wind and ice assumptions, temperature, installation tension and hardware.
Is GYFXTC8Y all-dielectric?
The product page describes an integrated metal messenger support element. If the project requires no metallic messenger, review an approved ADSS design instead.
Can GYFXTC8Y be used for direct burial?
The product page states that it is not intended for direct burial. State the installation method in the RFQ and select a construction designed for the confirmed route.
Need a GYFXTC8Y cable quotation?
Send the route, fiber requirements, span inputs, quantity, drum length and destination. MapleArashi can review the configuration before quotation.
