ADSS and GYXTC8Y fiber optic cables can support network expansion in Spain because they solve different field problems. ADSS cable works well for aerial spans near power lines, while GYXTC8Y cable is a strong choice for trenched and ducted sections that need armor, crush resistance, and stable optical performance.
On June 30, 2026, we shipped a fresh batch of ADSS and GYXTC8Y fiber optic cable to Spain. This was not a trial order. This was a 300 km order after the client tested our samples against three other suppliers. They needed cable for mixed terrain. Some areas had coastal humidity and salt. Some areas had inland hills and large temperature changes.
Why Did This Spain Project Need Both ADSS and GYXTC8Y Fiber Optic Cable?
A fiber project in Spain can look simple on paper. But the field is never one simple environment. One route may need aerial installation. Another route may need trenching. Another part may run inside ducts. The cable must match the route, not only the budget sheet.
This Spain project needed both ADSS and GYXTC8Y cable because the network route had different installation conditions. ADSS was used for aerial spans where the cable needed to share pole routes near power lines. GYXTC8Y was used for ducted and trenched sections where the cable needed steel tape armor, stable loose tube protection, and stronger crush resistance.
Route Conditions And Cable Selection
| Project section | Field condition | Recommended cable | Main reason |
|---|---|---|---|
| Aerial spans | Pole routes near power lines | ADSS | Non-metallic design and strong tensile support |
| Coastal areas | Humidity and salt exposure | ADSS / GYXTC8Y | The cable structure must match the exact route |
| Inland hills | Temperature changes and wind load | ADSS | Stable aerial performance under changing weather |
| Trenched sections | Soil pressure and handling stress | GYXTC8Y | Steel tape armor gives stronger mechanical protection |
| Ducted sections | Pulling, bending, and long service life | GYXTC8Y | Loose tube and armored structure support stable installation |

How Does ADSS Cable Perform in Aerial Spans Near Power Lines?
Aerial fiber installation needs a cable that can handle tension, wind, UV, and pole-line conditions. The cable may not sit in a calm place. It may face sun, storms, vibration, and sudden load. ADSS cable is designed for that kind of work.
ADSS cable performs well in aerial spans near power lines because it is an all-dielectric self-supporting cable. It does not need a metal messenger wire. It uses strength members such as aramid yarn to carry mechanical load. For this Spain shipment, we used a high-density UV-stabilized polyethylene jacket and an over-engineered aramid yarn design to help keep fiber strain under control during wind or ice load.
ADSS Structure For Aerial Use
| ADSS design point | Why it matters in Spain projects |
|---|---|
| All-dielectric structure | It supports aerial installation near power lines |
| Self-supporting design | It reduces the need for a separate messenger wire |
| Aramid yarn strength member | It helps control tension and fiber strain |
| UV-stabilized PE jacket | It supports long outdoor service life under sunlight |
| Outdoor loose tube structure | It helps protect fibers against field stress |
Spain has many outdoor network routes with strong sunlight. UV exposure can damage a poor jacket over time. The cable may look fine after delivery. But after years of sunlight, a weak jacket can harden, crack, or lose protection.
For this batch, the ADSS jacket used high-density UV-stabilized polyethylene. We use this type of jacket compound because we have long field experience in Chile and Argentina, where UV exposure is also a major outdoor challenge.
Aerial cable is not only about hanging fiber from one pole to another. Wind can create movement. Weather can create sudden load. Long spans can increase tension. Poor tensile design can push stress into the fiber. That may lead to attenuation change or long-term reliability problems.
Why Is GYXTC8Y Cable a Strong Choice for Trenched and Ducted Sections?
Ducted and trenched fiber routes need a different type of protection. The cable may face pulling force, side pressure, soil pressure, and handling stress. Aerial strength is not enough. The cable also needs armor and a stable loose tube design.
GYXTC8Y cable is a strong choice for trenched and ducted sections because it uses a steel tape armored loose tube structure. This structure gives better mechanical protection in underground or duct routes. For this Spain batch, we performed extra crush testing at 4,000 N per 10 cm, and we saw zero attenuation change during the test.
GYXTC8Y Cable Protection
| GYXTC8Y feature | Field value |
|---|---|
| Steel tape armor | Helps protect the cable against crush and external pressure |
| Loose tube structure | Helps keep fibers stable during temperature and mechanical stress |
| Jelly-filled tube | Helps protect fibers from moisture movement |
| Outdoor jacket | Supports long-term use in outside plant routes |
| Duct and trench suitability | Fits sections where aerial ADSS is not the best match |
Crush resistance matters because underground and ducted cable does not always live in a perfect environment. Workers may pull cable through long ducts. Cable drums may be moved many times. Soil pressure may change after installation. A weak cable may pass the factory test but fail after real handling.
For this Spain shipment, we did extra crush testing on the GYXTC8Y cable. The test condition was 4,000 Newtons per 10 cm. The result showed zero attenuation change. This result gave the client more confidence before shipment.
For this batch, the jelly-filled tubes used a compound stable from -30°C to +70°C. This helped the cable support Spain’s mixed outdoor conditions. It also helped protect the fibers from stress caused by temperature changes.
What Factory Tests Did Alteoptic Run Before Shipping the 300 km Cable Order?
Many cable problems do not start in the field. They start when inspection is too light at the factory. A cable can look normal outside, but the fiber may show risk after spooling, temperature change, or mechanical stress. We prefer to find problems before the cable leaves our factory.
Before shipping the 300 km order to Spain, Alteoptic tested every drum with 100% attenuation testing on every fiber at 1310 nm and 1550 nm. We also ran OTDR testing again after spooling. Then we randomly selected ten drums for full temperature cycling from -40°C to +70°C while watching the attenuation curve.
Inspection Steps For This Spain Shipment
| Test item | Test scope | Purpose |
|---|---|---|
| Attenuation test at 1310 nm | Every fiber, every drum | Check optical performance |
| Attenuation test at 1550 nm | Every fiber, every drum | Confirm stable transmission performance |
| OTDR test after spooling | Every drum | Check fiber condition after drum winding |
| Crush testing | GYXTC8Y batch inspection | Confirm armored cable mechanical stability |
| Temperature cycling | Randomly selected ten drums | Check attenuation stability from -40°C to +70°C |
| Final drum inspection | Full batch | Confirm label, packaging, and traceability |
Some suppliers only test fiber before final spooling. We do not think that is enough. Spooling can create bending stress and handling stress. If a cable has a hidden structural issue, it may show after winding.
That is why we tested again after spooling. We wanted to see the real condition of the finished drum, not only the cable before packaging. This step matters when the cable will travel across the ocean and then go straight into a project schedule.
For this Spain order, we randomly pulled ten drums and ran full temperature cycling from -40°C to +70°C. The goal was not to make a nice test report. The goal was to reduce field risk before the cable reached Spain.
How Does Alteoptic Package and Trace Fiber Cable Orders for Ocean Shipping to Europe?
A strong cable still needs strong shipment control. Ocean transit can create vibration, moisture, container movement, and handling risk. If packaging is weak, the cable may arrive with drum damage or unclear documents. That can slow down project receiving.
Alteoptic packaged this Spain cable order with vapor barrier wrap, desiccant packs, flange edge protection, and container loading designed to reduce movement during ocean transit. We also prepared test reports in weatherproof pouches on the drums and sent digital copies before the shipment left. Each batch had traceability from raw PE pellets to final drum serial numbers.
Packaging Details For The Spain Shipment
| Packaging or document item | Why we used it |
|---|---|
| Vapor barrier wrap | Helps protect drums during ocean transit |
| Desiccant packs | Helps reduce moisture risk inside packaging |
| Edge protection on flanges | Helps prevent drum edge damage during handling |
| Controlled container loading | Helps reduce movement during shipping |
| Weatherproof report pouch | Keeps test documents readable on arrival |
| Digital test reports | Helps the client check documents before receiving |
| Drum serial number tracking | Supports batch traceability and audit needs |
Traceability is not only useful when a problem happens. It also helps professional clients manage audits, project records, and supplier quality control. For this shipment, we kept full batch traceability.
We can trace raw PE pellets, preform data, production records, test reports, and final drum serial numbers. If a client needs a file for an audit, we can pull the record quickly. This is important for buyers who manage long-term fiber network assets.
Small shipping details can save a lot of time during receiving. A weatherproof pouch can protect test reports from rain. A clear drum label can help the warehouse team sort cable faster. Digital reports can help the project team review documents before the container arrives.
