GYTA Fiber Optic Cable: Comprehensive Product Specification
Product Overview
The GYTA Fiber Optic Cable is a stranded loose-tube, non-armored outdoor cable designed for reliable high-performance data transmission in diverse environmental conditions. The designation "GYTA" follows Chinese national standards (GB/T), where "G" stands for optical fiber cable, "Y" denotes polyethylene (PE) outer sheath, "T" indicates the cable contains a metallic moisture barrier component, and "A" specifies the aluminum-polyethylene laminate (APL) tape used as the radial moisture barrier .
Construction & Design
The cable's layered "defense-in-depth" architecture ensures exceptional protection against environmental and mechanical threats :
Optical Fibers: Single-mode (G.652D, G.655, G.657A) or multimode fibers (OM1-OM4), available in core counts ranging from 2 to 288 .
Loose Tubes: Fibers are housed in semi-rigid buffer tubes filled with water-blocking thixotropic gel, preventing moisture migration even if the jacket is compromised .
Central Strength Member: A steel wire or FRP (fiberglass) rod runs through the core, providing tensile strength during installation and long-term stability while minimizing microbending loss .
Moisture Barrier: A longitudinally corrugated aluminum-polyethylene laminate (APL) tape is wrapped tightly around the tube bundle, serving as both a radial moisture barrier and rodent protection .
Outer Sheath: A thick, UV-resistant black PE jacket shields against abrasion, chemicals, and temperature extremes (-40°C to +70°C) .

FAQ
Q1: What is the difference between GYTA and GYTS cables?
GYTA uses an aluminum-polyethylene laminate (APL) moisture barrier, making it lighter and more cost-effective for general-purpose outdoor use. GYTS employs corrugated steel tape, offering superior crush resistance and rodent protection for higher-risk environments .
Q2: Is GYTA cable suitable for direct burial?
While GYTA can be directly buried in some cases, it is primarily designed for duct and aerial installation. For heavy direct burial applications requiring enhanced protection, the double-jacketed GYTA53 variant with steel tape armor is recommended .
Q3: What grounding requirements apply to GYTA cable?
GYTA contains metal (aluminum tape) and must be properly grounded at both ends when deployed aerially or near power lines to prevent dangerous voltage induction during lightning strikes or power faults .
Q4: What is the expected service life of GYTA cable?
With proper installation and maintenance, GYTA cable delivers a service life exceeding 30 years, thanks to its robust construction, water-blocking layers, and UV-resistant PE sheath .
Q5: What fiber types are compatible with GYTA cable?
GYTA supports multiple fiber types including single-mode options (G.652D, G.655, G.657A1/A2) and multimode options (OM1, OM2, OM3, OM4) .
Standards Compliance
GYTA cables comply with international and Chinese standards including YD/T 901-2009 and IEC 60794-1, ensuring global interoperability and quality assurance .
