What is OSP Fiber Optic Cable?

OSP application

1. What is OSP fiber optic cable?

Fiber optic cabling can be divided into OSP and ISP according to the engineering construction. OSP stands for outside plant, and OSP is an outdoor project, and similarly, ISP stands for inside plant and is an indoor project.


2. Types of OSP outside plant

Aerial fiber optic cablelow cost;

Short construction period;

Fewer restrictions on the construction environment

vulnerable to damage;

bad security

Suitable for mountainous, rural, and other areas, generally used for local relay network
Direct buried fiber optic cablenot easy to be damaged; good securityA large amount of engineering; high cost; not easy to expandSuitable for areas with flat terrain, generally used for long-distance backbone networks
Duct fiber optic cableEasy to expand; good securityLimited construction environmentMainly used in cities and other areas with less space
Submarine fiber optic cableSuitable for transoceanic transmission, more secureHuge amount of work; very expensiveInternational communication optical cable across the ocean
Power line aerial fiber optic cableEconomical and fastRestricted by power grid topology; strong electrical environment damage; difficult to expandIt is suitable for the installation of optical cables using existing towers in the power sector

3. OSP outside plant assembly

  • Main engineering materials: optical cables, splice boxes, patch panels, overhead poles, etc.
  • Construction equipment: air compressor, cable blowing machine, welding machine, etc.
  • Test instruments: OTDR, optical power meter, oscilloscope/spectrum analyzer, etc.
  • Maintenance equipment: cable detector, ground resistance tester, GPS, etc.

4. OSP outside plant application scenario

4.1 Duct application scenario

Cement duct: 3 holes, 4 holes, 6 holes


  • High strength
  • Heavy, 0.6m/piece
  • Rough wall, poor sealing

cement duct

PVC duct: PVC duct, PE subduct


  • Lightweight
  • Smooth inner wall
  • 6m/piece

PVC duct

HDPE pipe: HDPE pipe, Silicon-core inside


  • Low friction
  • Good sealing
  • Flexible
  • 2km/roll

HDPE pipe

Tube bundle: Micro pipe, Micro cable


  • Lightweight
  • Smaller diameter

4.2 Aerial application scenario

Aerial fiber optic cable: ADSS cable

ADSS cable features:

  • All Dielectric Self-Supporting
  • Non-metal component
  • Easy installation
  • Long spans
  • Customized available
  • Low cost networks

ADSS Dual Sheath 001

ADSS cabling:

  • Fast, one-step installation with attachment hardware
  • Without interrupting electrical service normally

adss cabling

ADSS cable areas:

  • On pole lines
  • On power lines
  • On street lighting poles
  • From building to building


Aerial fiber optic cable: Figure-8 cable

  • All tension is taken by steel messenger cable.
  • The fiber configuration remains stress-free.
  • Require a lot of care on grounding procedures when installed on pole lines.


Aerial fiber optic cable: OPGW (Optical fiber Ground Wire)

  • Ground wire
  • Optical fiber inside
  • Apply to the high-voltage grid

OPGW cable

4.3 Special barrier handling application scenario

Cross road: Pipe jacking

  • Minimal influence on traffic
  • Consideration of residents and the environment
    cross road-osp

Cross river: Bridge

  • Low cost
  • Easy to implement
    cross river-OSP

Cross river: HDD

  • Horizontal Directional Drilling
