Description

Single-mode or multi-mode fibers are positioned in a high modulus loose tube, which is filled with a water-resistantcompound.
One metal strength member is in the centre of cable, which is covered by PE for some cores cable.
Centre strength member is stranded by loose tubes into compact and circular cable core, which is filled water-blocking material.
PSP is longitudinally applied over the cable core and PE sheath is extruded. (max. 144 cores)

One metal strength member is in the centre of cable, which is covered by PE for some cores cable. Centre strength member is stranded by loose tubes into compact and circular cable core, which is filled water-blocking material.
APL is longitudinally applied over the cable core and PE sheath is extruded. To compare with GYTS, tensile strength of GYTA is weaker, but it weights lighter and better water-blocking performance . (max. 144 cores)

Description

Single-mode or multi-mode fibers are positioned in a high modulus loose tube, which is filled with a water-resistant compound.
One metal strength member is in the centre of cable, which is covered by PE for some cores cable. Centre strength member is stranded by loose tubes into compact and circular cable core, which is filled water-blocking material.
APL is longitudinally applied over the cable core and PE inner sheath is extruded, then PSP wrapped and PE outer sheath. GYTA53 has both good tensile strength and water-blocking ability as GYTS and GTYA. (max. 144 cores)
