Double armor double sheath Outdoor optical cable

 

GYFTA53 optical cable is to put 250 & micro; M optical fiber is sleeved into a loose sleeve made of high modulus material, and the loose sleeve is filled with waterproof compound. The center of the cable core is a non-metallic reinforced core (FRP). For some optical cables with a number of cores, a layer of polyethylene (PE) needs to be extruded from the non-metallic reinforced core. The loose sleeve (and filling rope) is twisted around the central reinforcement core to form a compact and round cable core, and the gap in the cable core is filled with water blocking filler. Plastic-coated aluminum tape (APL) is longitudinally wrapped and then squeezed with a layer of polyethylene inner sheath, and double-sided plastic-coated steel tape (PSP) is longitudinally wrapped and then extruded with polyethylene outer sheath to form a cable.

 


 

Product application

 

•  Piercing

•  Overhead

•  Direct Buried

 

Product characteristics

 

•  Has good mechanical properties and temperature characteristics.
• The loose sleeve material itself has good hydrolysis resistance and high strength
•  The pipe is filled with special ointment to protect the optical fiber critically.
•  Good compression resistance and softness
•  The following measures are adopted to ensure the waterproof performance of optical cables:
  -Single nonmetallic center strengthening core
  -Loose sleeve filled with special waterproof compound
  -Full core filling
  -plastic coated aluminum tape (APL) moisture barrier
  -Double-sided plastic coated steel strip (PSP) improves moisture permeability of optical cables
  -Good water blocking material prevents longitudinal water seepage of optical cables
