Description

The HZL 24 Core Round Fiber Optic Cable (كيبل ضوئي قطري) is an outdoor armored single mode fiber optic cable designed for telecommunications, ISP networks, backbone connections, and fiber infrastructure installations.
This specific cable uses G.652D single mode fiber with a GYXTW-24B1 construction and is supplied on a 1000-meter / 1KM drum. The actual reel is identified as HZL-T5879-24C and has an outside diameter of 8.0 mm.
The HezrraLink GYXTW construction uses a protected loose-tube design with steel reinforcement and armor for outdoor network applications. The manufacturer's general G.652D specification gives maximum attenuation of ≤0.35 dB/km at 1310nm and ≤0.21 dB/km at 1550nm.
