Types Of Outdoor Fiber Optic Cable (Classified By Laying Method)

Aerial Optical Cable
1.Overview Aerial optical cable is outdoor fiber cable installed on utility poles. It features easy installation and cost-effectiveness, widely used for network construction.
2.Main Types Lashing Type Matched with steel strand messenger wire and cable hooks. Low cost, common model: GYTC8S GYXTC8S,Figure-8 Self-supporting Cable Built-in load-bearing structure, no extra messenger wire needed, neat layout for community and roadside lines. ADSS All-dielectric Self-supporting Cable Non-metallic structure, good lightning insulation, suitable for high-voltage power lines and long-span laying.
3.Advantages No trenching required, fast construction speed Low project investment Easy inspection, troubleshooting and maintenance Suitable for various terrains
4.Application Scenarios Rural broadband, township main lines, community access, road monitoring, campus private network, emergency communication lines.
5.Construction Notes Fix hooks evenly, keep cables straight Complete lightning protection and grounding work Reserve sufficient surplus cable for later splicing and maintenance.

Duct Optical Cable
1.Overview Pipe optical cable is laid inside underground communication pipes. It has strong protection and is widely used in urban main communication networks.
2.Common Models GYXTW, GYTS, anti-rodent armored pipe cable .
3.Advantages Buried underground, unaffected by bad weather Good anti-damage, anti-rodent and anti-theft performance Long service life, stable signal transmission Neat layout, no space occupation .
4.Application Urban main communication lines, community underground network, enterprise dedicated lines, large park backbone network.
5.Construction Features Lay cables into pre-buried pipes Reserve extra cable in manholes for splicing Avoid cable extrusion and abrasion Easy capacity expansion .
6.Disadvantages Higher pipeline construction cost, longer construction period, harder fault inspection than aerial cable.

Direct Buried Optical Cable
1.Overview Direct buried optical cable is buried directly into soil without pre-laid pipes, featuring highest protection and excellent stability.
2.Common Types GYTA53, GYTS53 double armored cable .
3.Advantages Fully underground, free from harsh weather Double steel armor, anti-pressure, anti-rodent, anti-damage Excellent moisture-proof and corrosion resistance Safe concealed layout, ultra-long service life .
4.Application Long-distance trunk lines, field communication, highway & railway lines, suburban backbone networks .
5.Construction Notes Dig standard cable trench for direct burial Lay fine soil at bottom for protection Mark cable route clearly Reserve enough slack cable at joints and bends .
6. Disadvantages High construction workload, higher cost, difficult fault detection and maintenance.
