Submarine Fiber Optic Cable

Overview of submarine fiber optic cable

Submarine optical cable refers to a kind of optical fiber cable laid in deep-sea or shallow sea, or in the seabed of river channel, which is used for optical signal and network signal transmission and connection.

Classification of submarine fiber optic cable

According to the application scope of submarine optical cables, it can be mainly divided into submarine single armour (SA) fiber cable, submarine double armour (DA) fiber cable, submarine single armour light (SAL) fiber cable, submarine light-weight protected (LWP) fiber cable, submarine light-weight (LW) fiber cable, submarine light-weight armour (LWA) fiber cable and their respective characteristics are as follows:

  •  Submarine light-weight optical cable (LW): generally suitable for deployment, construction and recycling in areas with a water depth of more than 1000 meters and at least 8000 meters deep.
  • Submarine light-weight protected optical cable (LWP): Generally suitable for deployment, construction and recycling in areas with a water depth of more than 1000 meters and at least 8000 meters deep, but it has certain anti-wear and anti-fish bite capabilities.
  • Submarine light-weight armour optical cable (LWA): Generally applicable to the deployment, burial, construction and recycling in areas with a water depth of 20 meters or more and at least 1500 meters deep. If it is not buried but only laid on the seabed, it can be applied It is deployed, constructed and recycled in areas reaching a water depth of 2000 meters.
  • Submarine single armour optical cable (SA): generally suitable for deployment, burial, construction and recycling in areas with a water depth of more than 20 meters and at least 1500 meters deep.
  • Submarine double armour optical cable (DA): generally suitable for deployment, burial, construction and recycling in areas reaching a depth of 500 meters, and provides the protection required within this depth, and should have a certain weight to prevent tides waves from moving submarine cables.

Optical cable type

Typical applicable environment

Features

(LW) Submarine light-weight optical cable

1000m-8000m water depth, good and stable sandy seabed

Lightly protected, the center is a loose tube structure, surrounded by metal reinforced steel wires, and the outermost layer of medium density polyethylene sheath structure

(LWP) Submarine light-weight protected optical cable

1000m-8000m water depth, rough seabed, moderately abrasive environments or environments that may be bitten by marine food

Compared with subsea light optical cable, it adds metal tape and a second layer of polyethylene sheath to increase abrasion resistance and hydrogen sulfide corrosion resistance

(LWA) Submarine light-weight armour optical cable

20m-1500m water depth, rocky terrain, moderate tugboat hazardous area, suitable for 2000m water depth when not buried

Add light armored steel wire than submarine light fiber optic cable

(SA) Submarine single armour optical cable

20m-1500m water depth, complex rocky terrain, high-risk tugboat hazard area

Adds a layer of heavy-duty armored steel wire over submarine light-duty cables

(DA) Submarine double armour optical cable

0m-500m water depth, complex rocky terrain, high-risk tugboat hazard areas and high-wear areas

Adds two layers of heavy-duty armored steel wire to subsea light-duty cables
