2. Optical Fiber In Cable(ITU-G657A2)
Optical properties of the SM fiber areachieved through a germanium doped silica based core with a pure silicacladding which meets ITU-T G657A2, UV curable acrylate protective coating isapplied over the glass cladding to provide the necessary maximum fiberlifetime.
Geometrical, optical, and mechanicalcharacteristics of fiber in cable as the following table:

3.1 General Design
Optical fibers are housed in loose tubes that are made ofhigh-modulus plastic and filled with waterproof compounds.
FRP is applied as central strength member.
Loose tubes are SZ-stranded around the strength member.
Water blocking yarns are used in and over the cable core toprevent it from water ingress. Polyethylene sheath is applied over the cablecore as the outer sheath.
