The direct-buried fiber optic cables allow underground laying without usage of additional pipes. The cables stand up with added mechanical protection, moisture resistance, and environmental and biological hazards to rodents, termites, and fire. Below is a breakdown of the key categories, product models, features, and application scenarios.
These cables have been uniquely shielded to prevent any rodent and termite bites throughout their buried long-term use.
Key Products
GYFTA53-1: PSP armor + APLD (Aluminum Polyethylene Laminate with Steel Tape)
GYFTA54-1: PSP armor + Glass yarn tape + Nylon outer sheath
Features
Double PE/Nylon sheath for added physical and biological protection
Anti-rodent & termite protection
Stranded loose-tube design with water-blocking elements
Applications
Underground installations in biologically active zones
Telecom networks, where rodent damage risk is high
Adopting all-dielectric construction also diminishes electro-magnetic interference (EMI), and thus make them ideal for burial near power lines and electrified railways.
Key Product
GYFY53: FRP Central Strength Member (CSM) + PSP armor + Double PE sheath
Features
Non-metallic core with dielectric strength members (FRP)
Double-sheathed, moisture and rodent-resistant
Lower electromagnetic conductivity
Applications
Direct burial near electrical infrastructure
Environments requiring non-metallic cable solutions
Their construction allows them to function in situations where temperature is elevated or fire is imminent.
Key Product
GYFZS53: Fire-resistant structure + PSP armor + Double PE sheath
Features
Fire-retardant materials
High thermal and flame resistance
Ideal for safety-critical applications
Applications
Tunnels, subways, or subsea installations
Areas requiring enhanced fire protection
Typical direct-burial cables, durable and with low rodent protection provided.
Key Product
GYTS53: PSP armor + Double PE sheath
Features
Standard mechanical protection
Suitable for common underground applications
Cost-effective option for basic telecom projects
Applications
General underground telecom networks
Stable environments with moderate risk exposure
