Product Description

GYXTY Center Loose Tube Unarmored Optical Cable G652D Product Description
The GYXTY type optical cable places the 250um optical fiber in a loose sleeve made of high modulus plastic, fills the sleeve with waterproof filler, and adds a water-blocking material to the sleeve to make the optical cable watertight. Two parallel fiber-reinforced steel wires are placed at both ends, and the optical cable is covered with a PE sheath.
Product Features of GYXTY Center Loose Tube Unarmored Optical Cable G652D
Good mechanical properties, good high temperature resistance
High-strength loose casing, resistant to hydrolysis
Special casing filler, which plays a key role in protecting optical fibers

Opticlink have a total of 8pieces production lines, include FTTH drop cable, Central loose cable and stranded fiber cable production , modernized dust-free workshops, and high-performance processing equipment. From raw material procurement, to finished product processing, to product quality testing, to packaging and export, we have a full range of production lines. The following are some of the actual photos of the workshop


1. What is the GYXTY fiber optic cable used for?
GYXTY is a lightweight unarmored fiber optic cable with a central loose tube. It's ideal for overhead or duct installations where high mechanical protection is not required.
2. What is the cable structure?
This cable consists of a single central loose tube filled with water-blocking gel and reinforced with two parallel steel wires on both sides for basic tensile strength. It has a polyethylene outer sheath for environmental protection.
3. What fiber types are supported?
The cable supports G.652D and G.655 single-mode fibers, which are widely used in access networks, telecom lines, and FTTx deployments due to their low attenuation and high transmission performance.
4. Is GYXTY suitable for aerial installation?
Yes. Thanks to its light weight and simple structure, GYXTY is suitable for short-span overhead installations, such as pole-to-pole communication in urban or rural networks.
5. What are typical applications of the GYXTY cable?
GYXTY is commonly used in:
Aerial fiber deployments
Conduit or duct installations
FTTH/FTTx access networks
Environments with minimal mechanical stress
