Product Description

Outdoor Stranded Loose Tube Corrugated Steel Tape Armored UG Duct Fiber Optic Cable Single PE Sheath 2-288 Core GYFTS/ GYTS

Single Jacket Steel Tape Armored Optical Fiber Cable is specifically designed for outdoor duct (pipe) laying scenarios (e.g., buried underground pipelines, municipal utility tunnels) and integrates mechanical protection, environmental resistance, and stable signal transmission. This kind of cable also can be used for Non-self-supporting Aerial laying which needs additional messenger support.

Cable Structure:

The 2-288 fibers are positioned in loose tubes made of high modulus plastic (PBT) and filled with gel. Tubes (and fillers) are stranded around the central strength member (FRP or Steel Wire) to form the cable core. Then an Corrugated Steel Tape (CST) is armored longitudinally around the cable core, which is filled with water blocking compound. Finally a PE or LSZH jacket is extruded.

Characteristics:

(1) Good mechanical and thermal performance
(2) Hydrolysis resistant loose tube
(3) Fiber gel ensures critical protection of fiber
(4) Specially designed stranded compact structure eliminating contraction of tubes
(5) Rugged, durable PE jacket protects against UV radiation, fungus etc.
(6) Crush resistance and flexibility
(7) Water-blocking measures :
- Loose tube gel-filled 
- 100% cable filling compound
- APL or CST moisture barrier

(8) Wide temperature range: usually from - 40 °C to 70 °C. This allows it to be used in various climatic conditions, from cold regions to hot and humid environments, ensuring the stability and reliability of optical signal transmission.

Applications:

GYTA/ GYTS Cable is widely used in outdoor duct-based communication networks, with core application scenarios including:
(1) Telecom Backbone & Access Networks
Deployed in municipal communication ducts to connect central offices (COs), base stations, and access points (e.g., 5G macro base station backhauls, FTTx (Fiber-to-the-x) trunk lines).
(2) Smart City Infrastructure
Used in ducts for smart grid communication (e.g., connecting substation control systems), intelligent transportation (e.g., traffic signal transmission), and IoT sensor networks (e.g., environmental monitoring sensors).
(3) Industrial & Enterprise Networks
Applied in factory duct systems to transmit data between production lines, control centers, and cloud servers (e.g., automotive factories, logistics warehouses)—the aluminum armor resists industrial dust and minor chemical splashes.
(4) Rural & Suburban Communication
Laid in underground ducts to extend optical networks to rural areas, avoiding damage from harsh outdoor conditions (e.g., wind, rain) and reducing maintenance costs compared to aerial cables.
