THE DIFFERENCE BETWEEN GYFTY, GYFTA AND GYFTS OUTDOOR FIBER OPTICAL CABLE
There are three kinds of non-metallic aerial optical cables.
They are GYFTS, GYFTA and GYFTY outdoor fiber optical cables.
GYFTY is non-metallic and non-armored, GYFTA is a non-metallic reinforced core, aluminum armored optical cable and GYFTS is a non-metallic reinforced core, steel armored optical cable.
GYFTS outdoor fiber optic cable
GYFTS is a widely used type of outdoor stranded loose-tube armored fiber optic cable specifically engineered for communication networks. It is distinguished by its blend of non-metallic structural reinforcement combined with lightweight metallic armoring.
The acronym breakdown reveals its layout:
- GY: Outdoor cable type
- F: Non-metallic central strength member (usually Fiber Reinforced Plastic / FRP)
- T: Filled structure (gel-filled loose tubes protecting the fibers)
- S: Steel tape armor (corrugated steel tape layer)
GYFTA cable
GYFTA cable is an outdoor stranded loose-tube armored fiber optic cable featuring a non-metallic core combined with a lightweight aluminum moisture barrier. It represents a precise middle ground between the all-dielectric GYFTY and the heavy steel-armored GYFTS, trading out steel tape armor for aluminum tape to optimize weight, flexibility, and corrosion resistance.
The alphanumeric code highlights its construction:
- GY: Outdoor cable type
- F: Non-metallic central strength member (Fiber Reinforced Plastic / FRP rod)
- T: Filled structure (waterproof thixotropic jelly inside loose tubes)
- A: Aluminum-polyethylene laminate (APL) moisture barrier armor.
GYFTY cable
GYFTY cable is an all-dielectric, non-armored outdoor stranded loose-tube fiber optic cable. The critical distinction between GYFTY and the GYFTS cable discussed previously is the complete absence of metallic elements or armoring in its construction.
The acronym breakdown maps its entirely non-metallic layout:
- GY: Outdoor cable type
- F: Non-metallic central strength member (Fiber Reinforced Plastic / FRP)
- T: Filled structure (gel-filled loose tubes protecting the fibers)
- Y: Polyethylene (PE) outer sheath
GYFTS vs. GYFTA vs. GYFTY
| Technical Feature | GYFTA Cable | GYFTS Cable | GYFTY Cable |
|---|---|---|---|
| Central Strength Member | Non-metallic (FRP) | Non-metallic (FRP) | Non-metallic (FRP) |
| Armor Material | Aluminum Tape (APL) | Steel Tape (PSP) | None (Non-armored) |
| Primary Advantage | Moisture barrier & Lighter weight | Maximum crush/rodent proofing | 100% Dielectric (EMI Immune) |
| Weight & Bending Radius | Lightest armored option | Heaviest & most rigid | Lightest & most flexible |
| Grounding Needed? | Yes (aluminum is conductive) | Yes (steel is conductive) | No (all-dielectric) |
