The difference between ADSS fiber optic cable and OPGW fiber optic cable from the perspective of structure.
Structural characteristics of ADSS fiber optic cable
The optical fiber is loosely sheathed in the cladding.
The structure of the cable core is laminated.
The wiring method is SZ wiring.
The outer sheath is protected against galvanic corrosion.
The main load-bearing component is aramid yarn.
Structural characteristics of OPGW fiber optic cable
Optical fiber unit (stainless steel tube. Aluminum coated stainless steel tube).
Metallic monofilament (aluminum clad steel, Aluminum alloy) perimeter reinforcement.
ADSS Optical Cable Performance Characteristics :
Aramid yarn perimeter reinforcement, good anti-bullet performance, the optical fiber is not injured by a shot at a distance of approximately 10 meters.
Metal free, resistant to electromagnetic interference, lightning and strong electromagnetic fields.
Excellent mechanical and environmental properties.
Lightweight, construction facile.
Use of existing towers, which saves line construction costs.
Can be erected electrically, which reduces losses caused by power outages.
Independent of the power line, easy to maintain.
This is a self-supporting cable, there is no need for hanging wires and other auxiliary suspension wires.
The performance characteristics of OPGW fiber optic cable
Full metal material.
Excellent mechanical and environmental performance.
Good compatibility with ground wires, with almost identical mechanical and electrical properties.
Allows fiber optic communication while diverting short circuit currents and directing lightning currents.
What is the difference between ADSS and OPGW fiber optic cable ?
OPGW is an optical fiber placed directly into the transmission ground.
ADSS is a self-supporting fiber optic cable, which is hooked directly to the transmission line.
All-Media Self-Supporting Fiber Optic Cable (ADSS) :
All-media fiber optic cable has excellent characteristics for preventing electromagnetic influence and lightning protection. Light, small outer diameter, use at height is very practical.
ADSS is also a good choice for the telecommunications industry in combating electromagnetic interference and high storm day environment..
In the future, a period of time of research on the ADSS cable to improve the subject is : how to meet the requirements of the premise, minimize the outer diameter of the ADSS cable, reduce cable weight, improve its tension resistance performance.
Aerial Earth Cable (OPGW) :
OPGW has been around for a long time and has been improved and perfected in recent years, using PBT in the fiber optic unit and adding a layer of stainless steel to the exterior of the casing.
In some cases, a layer of thermoplastic is added between the plastic casing and the stainless steel tube.
Stainless steel tubes can be laser welded over lengths of up to tens of kilometers, and the fibers are fully mechanically protected in such a multi-layer protection tube.
OPGW is made directly to the optical fiber in the transmission ground, ADSS is a self-supporting optical cable, optical cable directly suspended on the transmission line.
These two types of optical cable have been widely used in home electrical system, on these two types of optical cable also have special technical provisions.
