The GYTS Outdoor Fiber Optic Cable is a highly versatile and robust cable designed for demanding outdoor environments, including duct installation, direct burial, andaerial deployment when lashed to a messenger wire. Its core structure features optical fibers housed in color-coded, gel-filled loose tubes stranded around a central strength member. These tubes are surrounded by a filling compound for moisture protection. A key defining element is the Corrugated Steel Tape (CST) armor layer longitudinally applied over the cable core. This metallic armor provides exceptional mechanical protection against crushing, gnawing rodents, and other external forces. The cable is completed with a durable black High-Density Polyethylene (HDPE) outer sheath, offering excellent resistance to moisture, UV radiation, abrasion, and a wide range of temperatures. While not self-supporting like ADSS, it excels in duct applications and can be used aerially when properly supported by a separate messenger strand.
Robust CST Armor
Corrugated Steel Tape armor provides superior mechanical protection against crushing, rodent damage, and impact during installation and service life.
Loose Tube Design
Gel-filled buffer tubes protect fibers from stress and environmental factors, allowing for fiber movement and strain relief.
Central Strength Member
Provides tensile strength and resistance to elongation during installation and service.
Water Blocking
Gel filling in tubes and water-swellable tapes/yarns ensure longitudinal and radial water blocking.
Durable HDPE Outer Sheath
Offers excellent protection against UV radiation, moisture ingress, abrasion, chemicals, and extreme temperatures (-40°C to +70°C).
Versatile Installation
Designed for installation in ducts (conduits), direct burial in the ground, and aerial deployment (when lashed/cabled to a separate messenger wire).
High Tensile Strength
Suitable for pulling into ducts and withstanding aerial tension when lashed.
Good Flexibility
Despite armor, maintains sufficient flexibility for handling and installation around bends.
Wide Fiber Count Range
Available in various fiber counts to suit different application needs.
Outdoor Duct Networks
Primary deployment within underground conduits/pipes for metro, backbone, and access networks.
Direct Burial
Installation directly in the ground in trenches for routes without existing duct infrastructure (requires appropriate burial depth/protection).
Aerial Installation (Lashed)
Deployed aerially by being lashed or cabled to a pre-installed high-strength steel messenger wire using lashing wire or binders. Common in areas where duct burial is impractical.
Campus & Industrial Backbones
Connecting buildings via duct or aerial routes.
Inter-City & Long-Haul Links
Protected backbone infrastructure.
Areas with High Rodent Activity
Where CST armor provides essential protection against gnawing damage.
Harsh Outdoor Environments
Rugged construction withstands demanding conditions.
What does "GYTS" stand for?
"GY" typically denotes an Outdoor (Field) Cable. "T" often indicates Filling Compound (for moisture blocking). "S" stands for Steel tape Armor. So, GYTS signifies an Outdoor Loose Tube Cable with Filling Compound and Steel Tape Armor.
What is CST Armor?
CST stands for Corrugated Steel Tape. It's a metallic tape, usually galvanized steel, that is corrugated (formed into a wave-like pattern) and applied longitudinally over the cable core. This corrugation enhances flexibility while providing excellent mechanical protection, especially against crushing and rodent bites.
Can this cable be used for aerial installation?
Yes, BUT crucially, it is NOT self-supporting. For aerial use, the GYTS cable must be lashed or cabled to a separate, dedicated high-strength steel messenger wire. The messenger wire carries the tensile load, while the cable provides the fiber pathway and environmental protection.
Is it suitable for direct burial?
Yes, the robust CST armor and HDPE sheath make GYTS suitable for direct burial applications. Ensure proper burial depth and procedures are followed according to local codes and cable specifications.
