OEM GYTA53 Outdoor Fiber Optic Cable , Double Steel Aluminium Armored Fiber Cable

Factory Double Steel Aluminium Armored Underground Fiber Optic Cable 24 48 96 144 Cores Optical Fiber Cable GYTA53

In the GYTA53 cable, single-mode/multimode fibers are positioned in the loose tubes, the tubes are filled with water blocking filling compound. Tubes and fillers are stranded around the strength member into a circular cable core. An Aluminum Polyethylene Laminate(APL) is applied around the core.

Cable structure

The optical fibres are housed in loose tubes that are made of high-modulus plastic and filled with tube filling compound. The tubes and fillers are stranded around the central strength member to form a cable core.The cable core is armored with aluminum tape,then an inner PE sheath is extruded.The inner sheath is armored with corrugated steel tape,finally an outer PE sheath is extruded.

Fiber core number and fiber type:

The number of fiber cores can be selected from 2 to 288. There are the following optical fiber options:

1,Single mode optical fiber G.652.D(or G.652.B) ,G.655;

2,Multi mode optical fiber 50/125μm or 62.5/125μm,OM1 OM2 OM3 OM4 optional.

You can choose to use hybrid fiber according to the actual situation, such as the hybrid use of G.652.D

and G.655 fiber.
