GJXFH-1-2-4B6a1

Cable Description

The optical fiber unit is positioned in the centre. Two FRP are placed at the two sides. Then, the cable is completed with a white or color LSZH sheath.

Application

• Internal FTTH applications horizontal and riser, especially suitable for the last leg in FTTH systems.

Characteristics

• Special low-bend-sensitivity fiber provides high bandwidth and excellent communication transmission property
• Two parallel FRP strength members ensure good performance of crush resistance toprotect the fiber
• Simple structure, light weight and high practicability
• Novel flute design, easily stripand splice, simplify the installation and maintenance

Optical Fiber In Cable(ITU-G.657A1) 

Optical properties of the SM fiber are achieved through a germanium doped silica based core with a pure silica cladding which meets ITU-T G657A1, UV curable acrylate protective coating is applied over the glass cladding to provide the necessary maximum fiber lifetime.

Geometrical and optical mechanical characteristics of fiber in cable as the following table:

Packing

Cables are coiled on wooden or plastic drum. During transportation, right tools should be used to avoid damaging the package and to handle with ease.

Cables should be protected from moisture; kept away from high temperature and fire sparks; protected from over bending and crushing; protected from mechanical stress and damage.

Marking

Unless otherwise specified, the cable sheath marking shall be as follows:

• Color: Black
• Contents: Cable manufacturer or owner, the year of manufacture, the type of cable, length marking
• Interval: 1m

 

Delivery Length  

Standard delivery length is 1km/drum or 2km/drum . Other length available on request.
